Hey guys I downloaded the realtek audio drivers from crashctrl for my surface pro and they seemed to work wonders on fixing my microphone background noise, however, it disables the touch cover's key press sound. They say on their website that it will probably require some .dll files to be modified or something major to fix it but I have no idea where to start. Wonder if any of you guys have any idea on a fix or if someone could look into it. These drivers are great for fixing audio issues but this one bug that disables the keypress sounds on my touch cover sucks. Thanks!

I just got the LG Quantum and I tried to unlock it using MFG. Since then, I can't hear any sound on when I make/receive calls unless I put it on speaker mode or plug in a headset!
Does anyone know how to fix it???
Semi Solution
I'm not sure if this will ever get noticed, but I think I probably need to start about here since I'm having very nearly the identical problem (and I can't post in the forum that I felt was more applicable since I'm a lurker/noob).
I can actually fix it by opening appmfg (dial ##634# password appmfg#*#) and then I go into ELT Mode / Manual Mode / Audio Loopback then just exiting, and that starts the audio working properly again, but this doesn't persist through reboots, so I'm hoping to fix that.
If I go to Engineer Menu / Device Test / Sound Test / Audio Call Tool, I can play around in there with RX Voice CAL, RX Device Volume CAL, RX Stream CAL and Subsystem CAL. In RX Voice I can change the settings and they stay while on that screen but revert if I go out and back into the tool (for all Device Types). RX Device Volume keeps the settings but not through a reboot I think, and it doesn't seem like changing them changes the actually sound output anyway. Same for RX Stream Volume. But Subsystem won't change any settings though it lets you try. I'm not sure if this is where I should even be playing around to fix this problem, but in the appmfg its the only place I've found to mess with audio settings.
I'm hoping that its a registry change that occurs when I use audio loopback to reactivate my hardware speakers and that I can apply that tweak permanently, but I'm not familiar with messing with WP7 registry. How should I try to investigate that? I theoretically unlocked my device, I've been thinking about sideloading a registry tool but I haven't just yet, I'd like to see what folks think about the problem in general. I did try going back to 7.0 but it was no different than 7.5 for my audio. The other weird thing is that sometimes it will make notification noises all by itself, but it won't play music through the speakers or anything like that. This is a just for fun phone so it doesn't have a SIM, and I can't, like, return it or anything.
It seems like WP7 has a lot of audio glitches like this, I've found a number of similar threads with no solution for mine or to improve mine.

Anyway, if this gets noticed it'd be great if someone knows a better fix.
sound issue
i too am having a no handset audio issue. in test loopback modes all speakers work. the headset just isnt relinquishing sound to the handset, i was hoping someone out there knows the registry enough to tweak the sound options or make a super simple app that will let me select the speaker since the software maybe having an issue.
Hi, I recently installed CM10 v.0.9.2 on my Lenovo Thinkpad Tablet. Everything seems to work well, however the audio seems very high-pitched (not enough bass) and the maximum volume was not as high as I would like it to be. Two questions:
1. How does this mod handle audio (what audio drivers are used, ALSA, or other)?
2. Is ALSA installed? I noticed there was a directory /system/usr/share/alsa containing a configuration file, alsa.conf. If not, what is the best way to install it?
Thanks!
I have also noticed that the audio volume attenuates significantly when 'maximum' is reached using the volume button. However, if I back it off or make adjustments via the software settings, then it appears to improve (although not quite as well as I hope).
I would also appreciate some info and fix...
Audio drivers appear to be nvmm, Nvidia proprietary drivers.
Hi,
The sound from media and phone calls work only through headphones (phone calls will also work when tapping the speakerphone icon during a call). I've done a lot of Googling and it seems to be a known issue without a real fix (aside from installing an app called Soundabout). Does anyone know about this issue or what can be done? I have to believe there is a fix for this without a 3rd party app.
In addition, I recently installed Beanstalk and for some reason, the sound worked normally. After my first reboot, though, media and phone call sound only came from the headphones again. I did try formatting and re-installing, but it didn't help.
I know all of the hardware works, so there must be some kind of software fix. Any hard core Android developers willing to take this on?? Or anyone else know of a real fix?
TIA
Could be something in the headphone socket shorting it (e.g. moisture) try cleaning it out with Isopropyl alcohol. It might need to be replaced.

Thanks for the advice. I actually purchased and installed a brand new headphone jack, but the problem remains. Could it be a short on the motherboard?? I can dump log or bug files from my phone, but where would I go to have someone look and understand what the issue might be?
Thanks
I have been having a serious issue with my head unit ever since I got it. Well, actually, not me, but everyone who I talk to on my phone with it over bluetooth, in particular when my DVR is recording the dashcam. When the built-in DVR is recording the dashcam, it keeps making a loud buzz sound every 5 seconds to the receiving end of the call. That is, I don't hear it, but anyone I'm talking to on the other end of the call does. It is very loud and irritating, to such a degree that I have to turn off the DVR every time I'm in a call. Obviously, this shouldn't happen. Additionally, I find the same thing happens when making a call with Skype installed on the radio, which wouldn't be using bluetooth at that point, so it seems somehow either the dashcam itself (it is not the DVR software, I tried another software that did the same thing) or a hardware issue is creating noise on the line-in or mic in the sound system that goes out to the other end of the call. I've tried support from the "manufacturer", but they aren't much use and I don't intend to send the unit back to China and wait to get it back for 4 or 5 months. I suspect it isn't likely to be the dashcam, so for some reason there seems to be feedback on the USB line to the sound module.
So, I'd appreciate any ideas here. I've also tried numerous other DVR apps, but it seems that pretty much none of them function correctly with the USB dashcam that came with the radio. I don't know if it's an issue with the specific camera or that it's a USB interface for the camera. So, I'd appreciate any experience anyone can offer to resolve this.
Other than these issues, I've got it working the way I want. I installed a cooling fan on the PX5 CPU. I need to put a capacitor in parallel with it still as I think it's causing the LCD to flicker slightly. It came with Android 8, so I installed Android 9 on it. Upgraded the MCU. I also replaced the plain WIFI antenna wire with a plugin port so I can connect a better wifi antenna. I found an app that allows me to force a normal reboot instead of the pseudo-reboot it does with the power button because Android sometimes needs an actual real reboot.
There are some really annoying quirks about the radio too that if anyone knows how to change I'd be very grateful. For one, the Accessibility Services keep getting disabled when the radio is shutdown with the car. It seems to be a memory function built into the device as it doesn't happen with a real normal reboot. Also, the wifi sometimes gets shut off, I assume for the same reason. And the lack of security really really bugs me.
That's not an issue it's a feature I guess they didn't want to dedicate a PCB layer to route analog signals I even wonder if they have a dedicated layer for power. Anyway the problem is they run analog lines next to/under digital lines and no ground plane to isolate the 2. There is a mic mod thread that addresses those issues if you're interested.
Maybe just installing an external mic would be sufficient if your HU already has a connector for it. As for your other issue, check the factory settings menu there should be a setting to restore the unit to previous state on reboot. Sorry I can't remember the exact name of it.

I have an external mic. It doesn't help. Thanks for pointing me in the direction of the mic mod. It's probably what I've been looking for. As for the factory settings, I don't seem to have an option to restore the unit previous state in my factory settings.
Hi all,
I'm writing here in the hope of getting some better understanding of how microphones works, and maybe some hints on how to fix the problem I'm currently banging my head on.
I'm porting the Xiami Redmi Note 7 Pro to Ubuntu Touch, and I'm facing an issue with the audio recorder from the microphone: the top microphone works perfectly, whereas the lower one (the one used for phone calls) records a lot of background noise, in addition to the voice. I've spend several days trying to debug the issue, trying different stuff both with the kernel and with the mixer_paths.xml configuration, but every time when I thought I fixed the problem, after some reboots the issue was back.
I believe that the noise that the microphone is picking up is coming from the internal device circuitry: the noise changes depending on whether the screen is on or off, and it also changes when, for example, I'm scrolling a page. I think I do not hear this sounds when the device is running LineageOS, but I didn't try it extensively, so I might be wrong.
So, my questions are these:
if these sounds are indeed coming from the circuitry, how is the microphone supposed to deal with them? Is this what the noise cancellation is meant for?
Is there a generic way to enable/configure it?
And why is the upper microphone not capturing these sounds?
Can you recommend me some documentation to learn more about this issue (especially how it's dealt with in Linux or Android)?
Any help will be appreciated For complete reference, I believe that the audio SoC on the Snapdragon 675 is made up with the TI TAS2563 and with the Qualcomm Aqstic wcd937x.
