Hi Guys,
I'm new here. I have extensively search this forum to find an answer to my problem.
I have a re-branded phone, myPhone a919i from the Philippines or the Micromax A116.
All my audio, is producing a "screeching" sound; like "kshhhhhhhhhhhhhhhhhh". I can't play properly all media that requires sound.
I have also read that this might be due to voltage supply of my speaker and headset port.
Here's a very odd diagnosis.
1. When listening to any media with sound, it produces a screeching sound.
2. When listening to any media even with headset or loudspeaker, it produces a screeching sound.
3. When using loudspeaker in a call, it also does that.
4. I can't hear my friend on the other side when not on speaker.
5. When using loudspeaker while on RADIO FM, it screeches.
5. But when I'm listening to FM radio using headset, everything's normal.
So basically, to listen peacefully amidst of chaos, Radio FM is my friend.
Stuffs I tried:
1. Restore my backup from TWRP before this happened. -> Same thing.
2. Restore to Factory Settings. -> Same thing.
3. Tried 3 Custom ROM's -> Successful Flashing but sound screeches.
4. Voltage Control downloaded via Google Play -> Set the Governor to "ondemand" and WOAH it return to normal. But the happiness is short-lived. It goes back "randomly" to its screeching habit.
It's getting frustrating because I can't exactly pin-point the cause of this issue. But I still pray it's software, because on Radio FM, everything works fine when using headset. I don't know though if experts here would agree to me. I need your expert advice.
Can anybody lend me a hand?
Custom ROMs I've tried:
- YONIP v3.5
- YONIP v5
- StarkHD 4.2.1
Thank you in advance.

Just recently bought the iPhono mini BT450Rx to use with my SX66 with WM2003SE. Cannot make all features work at the same time. Here's the story. The mp3 players I'm using are WMPlayer and TCPMP
Installed Broadcom stack 3900 I got "hands-free" and "High Quality Audoi" working, but play/pause/stop/Prex/Next buttons on right earphone wouldn't work. Volume buttons do work.
Here I'd like to notice, that I also have Motorola HT820 BT stereo and its perfectly working with this stack with all buttons, receiving calls and so on. The only problem with HT820 I found so far: if I'm listening mp3 and there's an incoming call and I've answered it without pausing mp3 player, then, after end of the phone call I have to disconnect and reconnect BT Audio device in BT Manager. However, if I put mp3 player on pause and pick up the call, then I can just continue listening.
I tried to change the BT driver and found the one from HP for HP BT stereo, (which I also tried initially, but because it doesn't have "hands-free", I returned it and bought Motorola). It was downloaded from HP site, dont have link right now, but the exe filename is SP3003.EXE. The driver's version was 1.6.0700
Having installed this one I got stereo AND buttons working with mp3 player, but "hand-free" stopped working, probably because the driver is intended for the stereo headphones only, not the "hands-free".
Making some researches I realized, that the part that controlls buttons is sitting in the \windows\BTCeAvIf.dll file. So I extracted this file from HP 1.6.0700 driver, reinstalled Broadcom 1.0.3900 stack and replaced the file above. After all this manipulations, I got hansfree working, able to make calls BUT only to the moment when I connect Audio profile. At this moment I can listen mp3s, control, mp3 player with buttons on the iPhono mini, but cannot talk on the phone. However, if I disconnect "HQ Audio" profile in BT manager, the headset profile gets activated again.
This is pretty annoying, knowing, that HT820 works pretty well without all this tweaks.
Can anybody tell me whether I'm doing anything wrong, or if there's better drivers for iPhono, because I coudn't find another solution so far.
One of the good things with iPhono is it has 4 buttons in mp3 player mode play/stop/next/prev vs HT820 with play/next/prev.
The only thing, I cannot quite understand, since the stop button is also power/(make)answer the call button, how this device is going to determine whether I want to stop music or pick up the phone for making or answering call.
Hi there, I read your thread with a lot of interest cause i have the same problems as you. I purchased the BT450Rx too and had them paired with a Prophet, and I'm the same problems. Actualy, FF/REw works for me in WMP10, but not Pkay/Pause & Stop. Did you have any luck making them work?

I'd actually resolved some issues earlier, wth the exception that I was using TCPMP player instead of WMP and still could not answer the phone while listening to the music.
I was able to use all buttons but on some MP3 files, very misteriously they wouldn't work.
Unfortunately my phone got hardreset because of a deep freeze I coudn't take it out from, so I'm gonna need to reinstall BT again and tweak it again to make headphones work.
I actually love them, and have been using them most of the time, about 4 hours every weekday just for music and audiobooks, despite they suck as a phone headset
Anyone else have issues using DSP Manager at high volumes? The issue happens when using the phone speaker or headphone jack (didn't test bluetooth) and setting volume to ~85% or higher. The resulting sound is a lot of high pitch squealing that I imagine would be similar to what you would hear with a decoder issue.
To replicate the issue:
1) Launch DSP Manager, choose Headset (if you choose headset, I wouldn't put your headphones on for this test...or if you're running a line out to a stereo receiver, turn your volume all the way down) or Phone Speaker and disable all effects or select Menu, Reset.
2) Play any mp3 or streaming audio (ie Slacker, Pandora), adjust the volume to be within 1-4 clicks of max.
3) Go back to DSP Manager, enable Equalizer, and then adjust the low frequency slider (leftmost slider) to be above 0.
4) At this point, the sound issue should be noticeable if you're experiencing the same issue I am.
If someone can please test this and confirm they have the same issue I would appreciate it. I didn't find any other reports of this issue, but if it's a known problem, can someone please point me in the right direction to resolve the issue? I've tried this on 4 different ROMs (I think they may all be Cyanogen based) and I have the same problem with all of them.
Thanks in advance for any input.
Sorry man I couldn't replicate it on Nonsensikal 8.8. Used Pandora, set volume to within 2 clicks of max, and set <100 hz to .2 .4 and .6. Didn't get any kind of squealing. This was on phone speaker. I have had weird DSP issues in the past though. Just didn't care enough to try it on all the froyo roms.
Sent from my nonsensikal froyo using XDA App

I have the same exact problem. I cant even move anything without it going crazy. im running CELBFROYO 2.9
Thanks for your feedback guys, I'm going to try out Nonsensikal 8.8, will report back later.
Edit: I tried Nonsensikal 8.8 and still had the audio issues. Did a little research and I thought maybe I was experiencing "clipping". I don't consider myself an audiophile so I wasn't really sure if this was an accurate diagnosis of my issue. This lead me down the path to try out the Mixzing app since it has a built in EQ. Since the Mixzing EQ only functions on audio thru the Mixzing player, it's not an end-all solution since I find myself pulling up Slacker when I want a change of pace from the mp3s I have on my SD card, and the Mixzing EQ does not function for streaming music.
Anyway, I found the EQ in Mixzing to be quite helpful as it appears to actually detect when clipping is occurring and notifies you by change the EQ bands to red. The clipping I experienced thru Mixzing is not comparable to what I hear when using DSPManager. The Mixzing clipping results in the audio cutting out for a given frequency range - for example when clipping occurs when a bass drum is playing, you don't hear the full range of sound of the bass drum, the low frequency is cut off. What's also noteworthy here is that thru Mixzing, I was able to rectify the clipping issue by simply re-adjusting the sliders to their previous positions and the sound output was corrected. Whereas with DSPManager, resetting the sliders didn't fully resolve the audio issue, I was still able to discern a high pitch whine especially during quiet portions of a song until either the song ended, or I disabled the EQ. If this were related to a clipping issue, I presume the squealing I hear would go away when I reset the sliders to their previous positions, since the squealing persists, I think it's probably a decoder issue.
Something else I learned here, perhaps already evident to other users, is that for each frequency band you adjust in Mixzing, it requires additional processor resources. This might explain why the Eris (not sure if this plagues other phones) struggles here. And on that note, I was using my Eris to test the waters and help me determine if it's worth rooting and dropping a custom ROM on my Incredible. Since this sounds like it can potentially be a resource issue, and I haven't found other users on different phones experiencing this issue, I guess I'll take the plunge and try a custom ROM on my Incredible.
Issue started when flashing Passion (ICS) v5, but I have since ODIN 'ed back to stock, still broken. rooted and flashed CM7, still broken. My notification audio still works. My speaker phone during calls still works. My earpiece during calls does not work, and media audio will not play over speaker, earpiece, or bluetooth. Any help or guidance would be greatly appreciated.
Bringing back thread form the dead. I am having the same issue with my Vibrant. I bought the phone used and everything was working but now it all went out just like the OP. My earpiece does not work during calls but the speakerphone does work. Also, when using the phone for media, i.e. Youtube, the speaker does not put out any sound but during a phone call after I have turned on speakerphone Youtube media works over speakerphone. The audible touch tones and haptic feedback work during phone calls and sometimes during normal use. Notification sounds work all the time. The phone is running Eclair 2.1. I have tried resetting the phone to factory software and still no luck. Yesterday I opened the phone up and used an air can to blow out dust and it started to work but it went out again today. I am just looking to find out if this is a software issue or firmware issue? Thanks for the time and advice.
install "toggle headset2",and set the widget,you can control audio output manually
The earphone speaker is not longer working, i can use only headphones or loudspeaker.
External speaker is not working for media: music, games, youtube etc, But for ringtones and notifications it works fine.
I already tried to wipe the phone, was using custom ROM with stock kernel. I tried to run tests from service menu, bu all i can heas is... silence.
Wiping - didn't help.
Returning to 100% stock - didn't help.
Is there any way to track down the issue?
2 audio related Bugs I've noticed:
[Locked Bootloader, customised Nordic, full wipe clean install.]
1)
I use speaker phone on call a lot.
I'm noticing a much lower level of sound on speaker phone in call.
Even general audio playback is lower (tested certain YouTube tracks I listen to regularly, the levels are much lower then in LP.)
2)
When on a call. Again on speaker phone..... And playing YouTube or Music via the music app. The person on the other end of the call can here the playback?!?!?
Neither of these things happened on LP
Can anyone confirm?
You should let the phone settle for one day. I had this issue on both LP and MM on the first day of usage. The volume greatly increased the next day...it is some sort of calibration that the phone does.
Thankfully you were right.
Wahoo.
