Folks,
I am experiencing low mic volume output after installing cm-10.1-20130411-EXPERIMENTAL-p5110-M3 on a Samsung Galaxy Tab p5113. The application we are testing is video and in this case the mic volume is really low. This is a tablet to tablet skype like video session. Here the other end perceived very low Audio coming from the Tab with the CM-10.1-20130411-EXPERIMENTAL-p5110-M3. Stock ROM mic levels were fine. I read through a bunch of the forum and saw some folks noting this issue with other older CM builds.
Is there any file/value that I can modify at the OS level to manipulate the Volume output of the Mic?
Any other ROM's that you might recommend that handle mic volume/Audio/Video better than the ROM mentioned above?
Thanks in advance.

Aplha Widget
Just a follow up, This may help someone..
I was able to install the Alpha Widget app and it has a mic gain control function. Does anyone know what this gain control actually manipulates within the Android OS/Kernel? It would be great to manually manipulate this mic gain at OS / CLI level.
Thanks in advance.

I've been looking at playback volume issues. I notice that the Android maximum volume on the gen8 is lower than the maximum alsa-supported volume. So one can boost the maximum playback volume a bit by using alsa mixers.
I have a little script that does that, but it uses a modified version of amixer from the alsa-tools package. Unfortunately, I haven't yet found a way to build amixer outside of the giant gen8 buildroots package, which means that due to GPL issues the only way I can redistribute is by including the giant gen8 buildroots. That's annoying. If anybody has a better solution, that would be welcome.
trust me, you don;t want to boost the volume due to the speaker of gen8 is very weak and fragile, even the default maximum volume could break it without much time. I RMA once due to play music at maximum volume, and a lot of other people experience the same thing.
How about the headphones? Can one play through them at max volume? The archos ones seem very quiet.

True. But a software solution is preferred.
I might just tweak my little hack so it boosts only headphone volume, not internal speaker volume.
A smarter procedure would be to do digital range compression within alsa, and boost the apparent volume without actually boosting the maximum sound output. There are alsa filters for that, but I don't know how easy it is to insert an alsa filter.

Sure, but because of the GPL issues mentioned in my original post, it might not be helpful to you unless you've got the Archos Gen8 build environment installed.
I've already looked around at various options for boosting the volume on the phone, and I've run into issues at every point:
I've seen people reply to these threads saying that it's the headphones at fault: My headphones are fine. I'm comparing volume to an HTC Desire, and the SGS2 is distinctly lacking. And yes; I have plugged my headphones in fully
Another common reply seems to be that MIUI volume is higher than Stock so there is no issue. There is an issue: it's quieter than an HTC Desire!
Using *#197328640# to access Service Menu -- I'm running MIUI and therefore do not have the stock dialer, so codes don't seem to work. I could flash the stock ROM, do the code, fix the volume, but apparently the setting is lost after reboot -- so flashing MIUI after that is certainly going ot lose any settings.
I had a go with a couple of apps off the market, with low expectations, and they didn't work either.
I'm rooted (of course) and reasonably tech-savvy so I'm quite comfortable with a Linux system and ADB, quite happy to hack and patch. Is there any (permanent) fix I can apply to increase the volume? I'd prefer something fairly elegant, like applying the Service Menu options manually (somehow) at boot.
Have you tried Voodoo Louder?
Great tip, I wonder how I didn't find a reference to Voodoo before... I just bought the app and it seems to be working as expected!
Thanks a lot I'll test it through the day!
try the fix that in my signature then if u like to use voodoo louder u ear will blown lol
^^
+10000000000000 this ;-) Have been using Yahyoh's fix for a while now, have tried Voodoo Louder but this little app increases volume much more & also gives a "fuller"/less hollow sound.
Thanks for this info yahyoh, it's quite interesting that it's using
Code:
# alsa_amixer sset Headphone 31
I had a quick look (via BTEP) and found the names of the devices:
Master
Headphone
Speaker
Side Tone (NB. my previous research suggests playing with this will create echos in phonecalls -- so probably don't play with it!)
There are a bunch of others; I got the list via
Code:
# alsa_amixer | grep '^Simple mixer'
I am slightly wary of this solution, however, since it sounds like it keeps executing these "sset" commands on a regular basis (every second or so) and it doesn't seem like that elegant a solution. I'll stick with Voodoo for now, and if it isn't enough, I'll revisit this modification of the ALSA settings.
I'll pay special attention to the warmth of the sound, too, as I've installed the CyanogenMod DSP Manager, so thanks for the tip MistahBungle

Does that fix work on MIUI ROMs?

Yeah it will; MIUI is AOSP, as is CyanogenMod (which MIUI is based upon).

Apologies - I'm stupid today - bloody toothache
Yea the volume is way to low. I would love a fix. No programs
There is no fix without a program. That little app of Yahyoh's doesn't work with ICS, Voodoo Louder will give you up to 6dB extra volume with headphones/headset.
Does this increase system volume also?
would like to know this as well
the sgs2 just becomes picker with headphones - you gotta go with low impedance models. something like < 20ohms
truly a handheld, fantastic ..... very very fast ... comparing it with s2 I have to say which is better.! One big problem; headphone volume is very low, the speaker is perfect. Can anyone help me, thanks
Huawei P1 Low Volume
I felt the same with you, the volume should be louder. Anyone has a solution?
I have the same issue. Even I usually listen to the music via BT headset,in the car I connect P1 with the car radio through 3,5mm jack and output definitely needs to be louder. If there is no way,how to fix it in ,then we have to wait for the new firmware I guess.

Use Volume+ (NEEDS ROOT)

Ascend P1 low volume solution
This is a trick I figured out on my Huawei U8100 to boost volume that also works on the Ascend P1 (U9200). The effect is not huge but I guarantee you it works. This works explosively huge on the U8100, but Huawei seems to have "fixed" it partly on their new phones.
- Turn off/quit all music players, then start the FM radio.
- Click the "power" button to activate the FM tuner, then use the volume buttons to turn the volume *all the way down*. Not kidding.
- Press the home button and start your music player as usual. Adjust volume to maximum (the FM volume is maintained separately, so the tuner will remain quiet).
You can go back to the FM app and turn it on/off to see the effect. The difference is small on Ascend P1 but gives audio more punch and quality. The FM app will remember its volume setting when you start it next time. Running the FM app can also fix the problem of audio cutting out or quality going bad if you're not using the stock 4-contact headset.
In combination with this I use the latest version of Volume+ (I downloaded free version from the developer's web site). This version of Volume+ does *not* need root. Don't crank it too high because this can cause distortion. Use the EQ for best results, see image for my settings.
This app uses the Android EQ API available since Android 2.3. The Ascend P1 unfortunately has known problems with stereo imaging, which is the reason a bit of Stereo Widening in Volume+ helps.
Georg
PS: The FM app has a widget which makes it quicker to access to turn on/off. Lately I'm using a bit more gentle EQ, no bass boost, stereo widening = 1 for a more natural sound.
It works!
This seems crazy but it works, it´s not much more spl but it´s definetly better, anyway i bought a Fiio E3 Headphone Amp for 10 bucks in adittion to this trick and a litte bit of EQ my Ascend P1 it´s quite good

Thanks Urmet77... your fix is for rooted devices, I rooted my device yesterday and applied your audio configuration fixes, definitely works great. It is the definitive fix for the low volume problem, but requires knowledge of rooting, linux shell, and superuser commands. The best non-root solution is still my post above.
Good thing with Ascend P1 is that you do not need to replace your phone's ROM to achieve root. In other words, you just do enough of the rooting sequence to acheive su privileges, but can stop before flashing a new recovery ROM or firmware. I also did not lose any user data or settings, although you are still strongly advised to back up.
Some pointers for those interested, keep in mind it's possible to permanently disable (brick) your phone. You are solely responsible for any mishaps.
- Rooting guide: www . androidiani . com/forum/modding-huawei-ascend-p1/279692-guida-huawei-ascend-p1-u9200-aio.html
- You'll need both ADB and fastboot drivers from the Android SDK (step 2 under "First of all").
- Test Fastboot drivers using 'fastboot devices'. My Huawei showed up as "?", this is ok.
- Links to get Clockworkmod and SU_Busybox_Package.zip are in the second post of the rooting guide.
- I had trouble using volume keys to boot into fastboot/bootloader mode, had to use the ADB command "adb reboot bootloader".
- Do just steps 1 - 9 under "How to Root".
- Then you can apply Urmet77's volume fix: www . modaco . com/topic/361718-fix-low-earphone-volume-fix-for-huawei-p1-p9200-stock-ics-403
For the last step you'll need to know how to transfer files to and from your computer to the system partition, activate su, remount /system read-write, set/restore any required file/dir permissions. Remember a wrong command can brick your phone. I reduced the volume settings somewhat by editing the .conf files to be sure distortion is minimized, my settings in all 6 .conf files under [Music] ... <headset>:
Headset Playback Volume=12
DL1 Media Playback Volume=113
This is still plenty loud, thanks Urmet77. I still use Volume+ to add a bit of EQ and stereo widening, many EQ apps on Google Play do the same thing.
Now a shameless plug... I use this phone to develop my audio apps "SoundWire" (live audio transmission / wireless headphones) and Music VU (rapidly updating level meter and spectrum widgets for any music player). Look them up on Google Play.
Georg
Headset Playback Volume=12
DL1 Media Playback Volume=113
My default is 18 and 115 but it depends on earphones i dont have any disortion and u are welcome for the fix
Has the issue been fixed in official update?
Hi there,
I'm considering buying the phone, and I was just guessing, since the original posts are quite old, whether the issue has been solved in any of the official firmware updates released so far.
Thanks in advance.
Nice, now to figure out how to do it on a U9508 ^^

Hi.
Did any body find any method for fixing the headset low-volume bug in P1 LTE (U9202-L) in similar way ? I would appreciate any help.
Thanks

When.i.plug a.audio.jack.the audio level is reduce.
Do you know how.to.incresase the parameters without install a.new.rom, kernel, and without a S3 rooted ?
Thanks
Sent from my GT-I9100
Only with the look? Very easy question!!!
here's the solution
1. do you have a i9300 or i9100?
2. this is not where questions go, hit "report" and ask for it to be moved.
It is a safe function. It is for not damage your ears. If you listen the audio with the original earphones or a similiar earphones, there isn't be a problem, if you use a bigger earphones. You could listen the audio more low because, those bigger earphones needs more power. I don't know if I explain me.
Boeffla sound tweaks .

I have a i9100 rooted. And i use voodoo.louder apk.
For the.i9300 (used for my job) it's cant be rooted and i'm looking for how i can change the setup of the phone.
I know that make a protection. but i want to change it.
I'm going to ask for change this post sections.
Thanks
Try this:

There are some options for rooted users but the app does not need root to work.
Works on speaker, headset and bluetooth. It gives you an option of a simple EQ or a
very easy volume boost and allows you to set how much amplification you want.
I am using it right now in my I9300 with custom rom so it should work for you. It is not
however compatible with most other sound mods such as Acid which you should not have
anyway since you are not rooted.
You could try this. Lets you specify media volume when something is inserted into the jack

I solved myproblem.
Hi, I bought this device to replace a recently deceased Zune HD 64, but I'm finding the audio output really, really poor. It's so quiet.
At the moment I'm running the stock ROM 2.2.2, but I'm looking to improve this as using PowerAmp and it's Replay Gain setting just makes everything sound awful. The best solution I've found is to turn off EQ/Tone/Limit in Poweramp and disable Replay Gain
Is there some way to improve this? Installing a certain ROM for example? Is Direct Volume Control available on other ROMs and does it make any difference at all?
Not sure whether to install another ROM/Root the device as I'm looking for suitable performance & battery life.
Thanks for any replies/help received.

Other than that, disable "Direct Volume Control" in Poweramp. As a result, the maximum volume will stay the same, but the output of the voulme bar will be remarkably more gradual before the maximum is reached. Also, turning the EQ off might help if you want to listen to your music on a "flat" setting, though my advice is to switch to "loud": if distorsion occurs, lower the preamp bar.
I own another Samsung device, but if you browse through the forum I'm sure you can find custom roms containing audio tweaks.

Really? That's odd. When I was just using PowerAmp alone on my 4.0 it made everything sound great (I turned off limit), and yes DVC does make quite the difference. However, my solution is to use http://forum.xda-developers.com/showthread.php?t=2191223 Viper4Android. You can easily increase the audio output without losing sound quality. However, you need to update your Android OS to at least version 2.3. If you have the Galaxy Player 4.0. You can root it, install a custom kernel and install Voodoo Sound https://play.google.com/store/apps/details?id=org.projectvoodoo.controlapp&hl=en which also can increase the audio output on the player.
