UPDATE: Title changed to PARTLY SOLVED, because some users report this procedure is not working for them.
!WARNING! Before you enter the service menu and you go to experiment with one of these settings, keep in mind that some settings will NOT reset after a reboot or reflash and you can bring your phone in a state that it will not work as you expect.
KEEP YOUR HANDS OF THE SERVICE MENU IF YOU DO NOT KNOW WHAT YOU ARE DOING!
At least I solved my phone audio problems as described below....
Exact problem: I paired my SGS2 with a Parrot MKi9200 car kit. Music is perfect, phonebook is synced, voice dialing perfect, calling number in display, DTMF tones and other calling notifications are well.....but no audio during phone call...I could not hear anything and the caller couldn't hear me neither......
After 7 days googling, analyzing, headaches, to less sleeping hours ( )....I finaly found the solution this afternoon...
.... It is (of course) a very simple solution....but due to lack of service mode documentation I had to find out how this works exactly.
I found out that the Bluetooth audio level to my earpiece (Jabra BT500v) could easily be adjusted AND it actually stays the way I adjusted it after a power down (including removing battery).
The next step was to look for the Bluetooth audio level on my car kit. This was not the same (Bluetooth) setting p).
Well, a long story short.... here we go...
These are the steps I did to solve the phone call audio problem:
First of all REBOOT your phone so most (not all) values in service mode will be set to default value.
Second adjust the correct volume for a Bluetooth earpiece:
1. Go into service mode by the known code *#*#197328640#*#*
2. Select [5] AUDIO
3. Select [1] NB (VOICE CALL)
4. Select [4] BLUETOOTH
5. Select [1] Volume
6. Select [5] Sidetone: ..... (Could be any value, don't care about this value)
7. Select "MENU" - "Key input" and type 8000 and hit OK
8. Select [6] Rx Gain: ..... (Could be any value, don't care about this value)
9. Select "MENU" - "Key input" and type 0 and hit OK
10. Select [7] Tx Gain: ..... (Could be any value, don't care about this value)
11. Select "MENU" - "Key input" and type 0 and hit OK
12. Hit "MENU" and "Back" after each other until you are left out of the service mode
This will write the values into the audio chip.
I can confirm that because I tested it with reloading (and wiping) another ROM and the sound stayed exactly the same.
Third adjust the correct volume for a car kit like the Parrot MKi9200:
1. Go into service mode by the known code *#*#197328640#*#*
2. Select [5] AUDIO
3. Select [1] NB (VOICE CALL)
4. Select [4] BLUETOOTH(NREC OFF)
5. Select [1] Volume
6. Select [5] Sidetone: ..... (Could be any value, don't care about this value)
7. Select "MENU" - "Key input" and type 8000 and hit OK
8. Select [6] Rx Gain: ..... (Could be any value, don't care about this value)
9. Select "MENU" - "Key input" and type 0 and hit OK
10. Select [7] Tx Gain: ..... (Could be any value, don't care about this value)
11. Select "MENU" - "Key input" and type 0 and hit OK
12. Hit "MENU" and "Back" after each other until you are left out of the service mode
This will write the values into the audio chip.
NOTE: It is very important to go out of the servicemode by MENU and Back. This is the only way the values are written. I checked this in the log file of my SGS2. (By Android System Info app).
I can confirm the writing to the audio chip because I tested it with reloading (and wiping) another ROM and the Bluetooth audio phone volumes stayed exactly the same.
The other volume values are restored after a reboot (I checked a few of them), so that is easy.
Well, give it a try and let me and other users know the results.
UPDATE 04-09-2011:
Important notes about I2S values ("Sidetone", "RX Gain" and "TX Gain") in ALL audio menus:
- They are ONLY used for audio levels during phone calls. They will NOT change the volume when you listen to music or recording audio.
- They are ONLY saved by pressing "MENU" and "Back" until you have left the servicemode. My advice is to change them group by group, not all together.
- They are WRITTEN into the Audio Codec module. Rebooting, flashing other ROM's, wipe caches, wipe data, the secret code for factory reset WILL NOT RESET these values.
So when you messed around with these values and your audio during a phone call isn't working anymore (or the levels are too soft or too loud) you have to go into servicemode and put the values back into the Audio Codec module.
If you want to convince yourself of not resetting these values after reboot then try this:
- Set the levels ("Sidetone", "RX Gain" and "TX Gain") for the SPEAKER on 1000 (yeah, very high, gives a very loud annoying tone) as described above.
- Make a call to any number and put the speaker on..... beware of the loud noise then.
- You can try to play some music, and you will notice that the music is ok through the speaker, so this setting has no effect on playing music.
- Now switch of the phone and remove the battery
- After 5 minutes put the battery back and switch on the phone.
- make a call again and put the call on the speaker.... very loud noisy tone again.
- OOPS now you messed up your settings in servicemode....
- NO WORRY... put back value 0x35 and your speaker is working again.
(You can also try to reflash or wipe your phone, but believe me these settings do not reset to default).
UPDATE 05-09-2011:
Some notes on setting and reviewing values:
- All values set at "Sidetone", "RX Gain" and "TX Gain" settings will NOT show up again if you re-enter servicemode and check them. Actually you will see other (mostly much larger) values.
- If you made a phone call and used a specific device, for instance the speaker, and you re-enter the servicemode afterwards, the value will always show up as 0xffff.
Important: If you re-enter the servicemode and enter a specific device to check the "Sidetone", "RX Gain" and "TX Gain" settings, do not leave the servicemode by multiple 'MENU" and "Back". This will reprogram the Audio Codec with incorrect values. If you still want to look in this menu, then always enter the correct value for these 3 settings before leaving servicemode. If you leave servicemode by END or hard Back key, then nothing happens to these settings.
UPDATE 10-09-2011:
Devices: It seems that only one device can be set by the servicemode menu. The other devices will be set to some (unknown) values. (johho, Thanx for reporting this).
Echo during call: If I enter another value for sidetone (8000), then the echo is completely gone on my BT car kit and (almost) gone on the phone itself. If I enter 0 for sidetone, then there is a loud echo.
Levels: I now enter 0 for each device. This works for all devices I use (BT earpiece, BT car kit, Phone and wired earphone).
UPDATE 11-09-2011:
Sidetone and echo: sidetone is the effect of sound that is picked up by the telephone's microphone and feedback into the earpiece. If the value is to high, you will hear an echo due too the combination of the sidetone level and latency. Here you will find more interesting info about sidetone and echo: http://www.voip-info.org/wiki/view/Echo+and+Sidetone
Final solution working for me: I adjusted each device separately and now I got every device (wired earphone, handset, speaker, BT earpiece and BT car kit) working properly. All levels are OK and there is almost no echo anymore.
Because the BT car device resets to some defaults at which the car kit doesn't work anymore I adjust this device BLUETOOTH(NREC OFF) last.
I set 0x0 for TX and RX gain and 0x8000 for sidetone for all devices.
I adjusted the devices separately following this particular order:
[1] HANDSET
[2] HEADSET
[3] SPEAKER
[4] BLUETOOTH
[7] HANDSET(2MIC)
[6] HEADSET(3P5PI)
[5] BLUETOOTH(NREC OFF)
I am afraid that actually problem is more serious that we expected
1. I able to set those values in single audio device, but they reset to some stupid "defaults" as soon as I try to set the same item in another device. For example I have tried to set value for HEADSET(3P5PI) and then to regular HEADSET (or SPEAKER - no matter) and HEADSET(3P5PI) values reset to some defaults. With this defaults I don't hear anyone in my headphones.
2. Unable to change values for HANDSET(2MIC). No matter what I put there no changes in HANDSET calls. I able to adjust HANDSET settings (call with noise cancellation off), but as side effect #1, they will reset to defaults as soon as I put something for other devices. Looks like service menu has a bug and time to go to service (of course don't say anything about service menu).
BTW. this menu actually implemented as part of modem code. So it could behave differently on different modems. averjans, what modem are you using?
Hi vyurin,
Please look at my update on my previous post.
I'm using Lite'ning ROM PDA:XXKH3, PHONE:XXKH3, CSC:XAKH3
The modem is software is it? The hardware is the same for all SGS2's I guess?
It's a bit strange how the values are programmed by the servicemode. I think this software actually programs some registers into the Audio Codec which will retain after boot, flash and/or wipe data. I'm also quite sure that these values are read-only, because they never show up if I re-enter the settings.
Yes, I am talking about software. I also think so that we are directly programming some write-only registers (not sure now about audio chip, probably some output from modem part). But issues described in my post above make it impossible to properly program it. Do you able to confirm the same behavior during programming?
Btw, presence of background noise on high gains may indicate that output from modem is analog. I don't think that digital output could have a noise.
Btw2, In my case values will be saved as soon as I enter them, even if I leave service menu by home key, or Menu or End or Hard back key.
Could you attach headphones (one without microphone) and try to make a call? I afraid you will not hear anything, since by setting up bluetooth values, other one will reset to default. In this case making call using handset you probably can notice some background noise (noticeable in quite environment only) as well.
That's not gone well for me. I've gone from having quiet audio to no audio over bluetooth earpiece and the bluetooth in my car.
kcaz, Did you exactly follow my procedure? You should always hear something. If the values are too high, then you will hear nothing because the gain is much too high.
Be sure you program each value (BLUETOOTH and BLUETOOTH(NREC OFF) separate.
Procedure in short:
- Enter servicemode
- Go to BLUETOOTH audio setting
- Enter the 3 values
- Leave servicemode by multiple MENU and Back touch keys
Then program next value (BLUETOOTH(NREC OFF)
If it still doesn't work, check the other volume settings, they shoul be default after reboot.
I tried this a lot of times with different values and it always worked for me.
I assume you have a SGS2. What type of earpiece and car kit do you use?
I hope I can help you with this. I know it is an annoying problem and it must be solved...
Got it. I had programmed BLUETOOTH but didn't touch BLUETOOTH(NREC OFF).
I just went through the same procedure but did one after the other before testing. Works fine now, and it's a little louder.
Ok, great!.
If you want it louder, just put 0x32 in BLUETOOTH(NREC OFF).
If you follow the procedure correct, you can put higher or lower values until you are satisfied. If you go too high, it wil give a loud high tone or you hear nothing.
Cheers...
Hi Averjans,
Could you please check following scenario:
1. Set some high values for Speaker.
2. Then set high values for Handset(2MIC).
Make a call using Speaker. Do you still hear those high values?
My point that:
1. I able to set values only for one of devices, rest of them get some default values.
2. Unable to set any values for HANDSET(2MIC). They just doesn't work.
Hi vyurin,
I did some tests and indeed the speaker values reset to something default. Even when I set values for the speaker, the Bluetooth car kit doesn't work anymore because these values are also set to some default values which are too high for my car kit.
I'm going to find out more about this, but that can take a while.
Advise: adjust only the values for the device you need to work. I noticed that the phone itself (speaker, handset) always resets to defaults which will work. So when I set my values for the Bluetooth car kit, BLUETOOTH (NREC OFF), I have all necessary devices working.
I guess the servicemode is buggy OR we don't know how it works exactly.
When a device has been used and you go into service mode, the shown values are always set to 0xffff. This will ONLY be shown the first time you start servicemode after the call and enter directly the correct device. If you select a not-used device other values will be shown and you will not find the 0xffff values anymore. You have to make another call to set the 0xffff values again for the used device.
Maybe this can help you to find the correct device you should adjust.

..same here, I can only enter the values for one device..
I have problems with BT Headset AND Headphone.. With both i hear nothing.
When i enter the "32" value for bluetooth, the Headset works again!!! , but when I enter the "32" on headsed values after this, the BT Headset doesn't work anymore.. the "normal" cable headset doesnt work too, no mater which values I enter.
So it seems that i can only "fix" BT device..
Can you give me the exact procedure and keys you type in. Mayb I can see some new issues that can explain why its working for me, but not for you.
Tell me also the ROM version you are using (type *#1234# in the phone dialer). I have noticed that the servicemode app has changed since the first ROMs available.

Now reentering service mode and do exactly the same as before with "Headset"..
now bluetooth Headset doesnt work anymore...(nor Headset! )
hope this can help solve the iussue?
Btw, Service menu is the part of modem.bin. ServiceModeApp is just front-end. I just flashed KE4 modem and service menu a tittle bit different. But problem with programming Audio still exist. And seems to me it store this information in some NV memory, not in audio chipset. According to audio chipset datasheet I think it doesn't know anything about different type of in/out.
vyurin, Thanks for this info. Can you send me the datasheet of the audio chip? I couldn't find on the internet. I assume it is the YMU823 from Yamaha?
Do you know if the source of the modem part is also open souce? I was looking for this and can't find it. Thanks in advance.
download.yamaha.com/file/46319
Unfortunately there are no information about registers available.
About modem sources - no luck to find them. Probably it is simplest way to solve the issue.
About I2S(0,1,2) - it signal bus for Audio/Video devices for inter-exchange (as I read). Our processor has 3 of them.
i'm really really sad about this.. tryed to change volume on BT, Headset and Speaker, now my device is totally scrumbled.. I geto only one of the things working again by entering 32 as key value, the others doesnt work until i enter the same there, but than the other one which worked bevore stops working..
There muste be another way to reenter the correct values, specially while only this three settings (Gain) seems to make such problems. The other (dezimal) values are saved and stored correctly no matter what i enter as value.
I hope i'll get this working again, because atm my GS2 isn't really good to use without any comfort of headset or Bluetooth Headset
There must be any way to reset the entered values.. on GS1 it seems to work because this device has a reset switch in Service Menu
EDIT: newest crop after flashing diffrent Modems to test if this makes some diffrence: i hear a kind of echo even while using just the phone to phone.. So i hear my own voice a few ms after i spoke.. (Modem KH3)
i'd better never changed a thing in that damm buggy service mode..
johho, I heard echo after attempt to put something into sidetone field. Echo gone after reboot.
..ok i tested a lot the last hours..
its definitively that i can only change one device.
If I change the values on Bluetooth, the Speakerphone doesnt work anymore but bluetooth does. Even after reboot, reflashing etc.
If i now change Speakerphone, this works but bluetooth doesnt anymore.
Same with Headphone.
No matter what procedure I try this it the fact on my device.. Don't know why..
So it seems that my Audio Settings are totally scrumbled and im not able to set it back to working values for all connected devices..
BTW whats the diffrence between a) bluetooth and b) bluetooth (NREC OFF) and between c) headset and d) headset(3P5PI) ?
I found out that my BT Headset only works with changing the Values on Bluetooth(NREC OFF)
johho,
what I know is that headset applies to headset with microphone, headset(3P5PI) without microphone.
I experience the same problems - able to set only one device.
Hi,
I've been having consistent problems with volume, specifically being too low, and especially while connected to a bluetooth headset. I also noticed some odd, and likely related, behavior with the volume in general.
Here's how I see it: Start some music playing. Go to Menu > Settings > Sound > Volume and scrub the Media volume slider back and forth from 100% to 0% and back (and repeat).
On my Atrix, the max sound gets consistently lower each pass until it's silent, even at 100% setting. I think this is part of the issue with the media volume. As I adjust it up and down it loses some peak volume each time. I can bring it back up with a lot of tinkering (mostly through the OS volume controls and in PlayerPro), but I have not found the formula to deal with this in a normal way.
Has anyone else seen this, or can suggest a way to prevent or restore these volume anomalies? Running GB and rooted. Thanks!
I haven't seen this specific issue, but if you think the Atrix has volume problems, go try to use the Infuse without voodoo sound.
Are you saying I should try an Infuse ROM? I'm not sure what you're instructing me to do. Sorry for the extra clarification needed.
No, I'm just saying that your issues could be worse. The Infuse is another phone. Disregard my post if it confuses you.
I use PlayerPro also and have no issues over BT. I start my music playing, turn media volume up full via the volume up button, then control volume level after that with my headset.
I never go into the volume in settings, as it is greyed out for me. I am set on silent and vibrate always as I spend a lot of time in meetings.
My issue is not with PlayerPro or even BT (though it is more noticeable with it), the problem is that the audio gets progressively lower as I raise/lower the volume. PlayerPro does have some volume settings, which is why I mentioned it here.
I found an app called Volume+ that works fine with my rooted Atrix. It boosts the bluetooth audio. I still have the problems I listed above, but this one app may enough to get me over the hump.
I still would like to know what causes the strange volume behavior I'm experiencing above.
Does anyone here make calls using a headset? For some reason on my SGS2 the volume (and this is just for calls, music and media are fine) even at maximum is almost unlistenable. I just cant hear the other person.
Anyone know of a solution?
Ralph
anyone?
I have searched and found loads of threads saying "use the search function " but nothing that answers the issues. Probably a failing on my part I am sure!
Do you have the same issue during VOIP like skype?
Sent from my Nexus S using XDA App
Yeahm Music/Video/Podcasts are fine itr is just call volume through headphones. Having said that the maximum call volume even without heaphones is a little low for my tastes but through a headset is just to quiet to hear.
If you try skype or gtalk and you got big difference its due to the audiochip. Music and other apps got other internal settings inside the audiochip. Thats why I was curious if you got the same trouble with skype.
DONT touch any settings in the hidden service menu until samsung got a proper fix for it. The menu wont work properly with the audiochip of the i9100 and could f*** your device completly.
The audiochip will not be able to reset correctly even on hardreset or reflashing new fw.
Sent from my Nexus S using XDA App
The call volume through the headset on the S2 is notoriously quiet, the following will help increase the volume through the headset.
note: Use the menu key->Key input to enter values
1. Open the dialler
2. Dial *#*#197328640#*#*
3. Navigate through the following menus:
(5) Audio
(1) Voice call
(2) Headset
(1) Volume
(1) SRC Speech RX Volume
4. Enter 5100. This sets the maximum level (5) to the maximum volume (100).
5. Use the menu key, and select back six times to navigate back to the dialler.
The headset volume setting is now set to the maximum when the volume toggle switch is set to the maximum.
Note: When the phone is reset or powered off, the firmware will reset these settings back to the default, so you will have to go through this procedure again.
Hope it helps!
WARNING CAUTION!!!!!!!!!!!
Don't touch that menu if you don't want to risk anything.
Read about it here:
http://forum.xda-developers.com/showthread.php?t=1248729
That menu is for older devices with another audiochip not for the Yamaha chip thats in the Galaxy S2 device.
I have my phone at samsung Service center a second time due to big trouble with this menu!!
This menu only works like intended on older devices!!!
DO NOT TOUCH UNTIL PROPER FIX IS OUT!!!!!
Hi there does anyone know how to assign a app to use a different volume level? The problem i have is i use the pumpkin DAB+ app (i have attached to post) to listen to the radio and use tom-tom for navigation but the DAB app volume is much louder that the tom-tom volume so even when set to mute DAB when instructions are played it is too quiet to hear the instructions.
i have tried playing with the volumes in factory setting but it looks as if the DAB and tom-tom volumes are both affected by the system volume, if i lower the radio volume in factor menu and listen to the red radio app and use tom-tom then the instruction are much louder.
so my question is they a way to make the DAB app use the red radio app volume level.
Thanks in advance
You can go in the factory settings menu and change up the volume on 'system' to something like 15 (I tried 20 today and it almost made me jump out of the car when the directions came on!)
OK, back on this thread, which I know I posted a response to. But I didn't quite read the OP right.
I have the same issue that my GPS voice when radio is on is pretty quiet (even with the volume turned up), but when on DVD/streaming it is very loud. Is there a way to make them more equivalent.
Any ideas?
Hi , I have the same issue. When playing music over a music player such as poweramp , dvd or whatever the gps , either sygic or navigon, is perfect. As soon as I use the radio the gps volume is very quiet in both navigation apps. Im using the latest Malaysk ROM.
Thanks
Have you tried head unit system/gps/switching-mixing control ?
Sorry for not updating after my last post, what I have done is in the factory settings menu turned the radio right down (to 1 or 2), DVD down a bit (to 4 I think), system up to about 13 and the volumes are much better mixed. Its only a bit loud when doing Music from USB now so I'm getting there. Basically you need to turn some volumes down, and others up in the factory settings to get something to work for you.
Here's the fix if you have been struggling with this issue

Set the volume levels of correction for each full-time applications. When you switch to the application volume will be increased by the correction value, and at the exit reduced. So I solved the problem of the insufficient level of application volume "Music" in comparison with "Radio";

I have a RoadNavi S160 (Android) installed as a head unit in my car, stock speakers + undearseat subwoofer ( Connected to the rear speakers ). I have flashed the unit with rooted Kotix ROM which has a preinstalled V4A.
I've managed to get it to work with PowerAmp, but thats where it ends...
1. Which settings shoulld i be working with? (headset? speaker? bluetooth? USB? - or all of them? )
I have tried to play around with them, but i am totally lost! - only the speaker tab makes a difference to the sound.
2. The IRS files don't seem to make any difference to the sound ( I can change them, and driver status shows as processing )
3. With the equlizer only(no IRS) the speakers sound either too flat or too distorted
I am not after a highest quality audio, but would like to hear a nice punchy bass and decent vocals ( without cracking speakers! )
Thank you all
Can you use PowerAMP (the app itself?)
If yes! Well Poweramp uses something called "DirectMusicControl" so it will only use PowerAmp no matter what you set in Viper4Android!
Go to settings --> Audio --> Enhanced Settings (in my case the last point on Audio) --> First Entry is the "DirectVolumeControl"
Klick the box so it's unticked and play some music with poweramp while you open up Viper and set everything to your liking!
WARNING: Maybe you should reset ViperSettings to default if possible not that you blow away speakers
Thanks for the reply!
I have already managed to get those two to work together and since posting my initial question I've figured out the way to use the IRS's ( turns out I copied a folder full of files into the kernel, instead of extracting just the files into the existing kernel folder ).
But I must say that I am struggling to get it working as well as it probably can.
The settings within the "headset" tab seem to have no effect whatsoever, and only the settings from the "speaker" tab seem to make a difference.
Having said that, no matter what IRS I use, it just sounds wrong ( too quite, too loud, not enough bass or too much bass )
Thinking about it - is there a way to default v4a to set parameters within the headset tab instead of the speaker?
This would enable me to have a greater controll ( and possibly sort my issues ) over bass, clarity etc.?
Thanks
