[PEBCAK] GSI sound voice distortion high pitched (chipmunk) - Treble-Enabled Device Questions and Answers

Voices are distorted on video communication messenger apps like Element or Session.
Disregard, I had tried every permutation of the phh qualcomm tweak checkboxes EXCEPT checking ALL of them and rebooting. This exterminates the chipmunks.

I had the same problem with a Xiaomi Redmi Note 10.
Some GSI worked, some didn't.
The problem disappeared after I did a factory reset (reflash) from computer.

Do you use a kind of VoIP app? If so, try "Use alternate audio policy" in "Phh Treble Settings". I think your current "/vendor/etc/audio_policy_configuration.xml" lacks "AUDIO_OUTPUT_FLAG_DIRECT" flag at the "voip_rx" mixer part.

[Q] Leedroid DSPManager not working with A2DP

Hi,
I recently finally took the rooting plunge and installed Leedroid 2.3d, mostly for A2SD and DSPManager.
I cannot get DSPManger to work with my Motorola S305 A2DP headphones - turning effects on makes no difference at all. I have tried rebooting, restarting the HeadsetManager service and force stopping and restarting DSPManager.
I checked logcat while connecting the headset and the line "Bluetooth plugged: " + bluetoothAudio as specified in the DSPManager source in cyanogenmod is not there. At the begginning of the log I see a bunch of unhandled exceptions to do with DSPManager 'leaking' IntentReceivers, which could be related as it is supposed to be listening for BluetoothDevice.ACTION_ACL_CONNECTED, especially since it seems to create a bunch of BroadcastReceivers at start.
Will anything break if I try to compile the latest version from cyanogenmod github directly?
Ok, after some experimenting trying to get the cleanest logcat I could I've managed to make it work .
It seems it doesn't work until the service is restarted after an effect is enabled. It also doesn't work when all effects are disabled and then one is enabled until the service is restarted. It must be a bug of some kind with the bluetooth system as this doesn't happen with wired headphones.
DSPManager is awesome, especially the Virtual Room! It even works for Dolby Surround/Pro Logic encoded movies (only really noticeable for Room/Large Room/Stage)! . I always thought that was what Dolby Mobile did for the Desire but never could get it to work. I think the effect is at least as good as DTS SurroundSensation UltraPC Headphone (who came up with that name?), and certainly better than the Headphone Virtualization built in to Windows.

Notification sounds - audio cutting out

I'm on the latest stock firmware. Whenever I get a notification, the currently playing audio cuts out and takes about 10 seconds to return. It happens with AIMP (which I use because it has a eq / preamp) and the SoundCloud app. It's pretty frustrating and I've resorted to switching on Do Not Disturb, but that's not an ideal solution.
(Side note - audio on android is a pain. I've tried Viper4android on 2 different phones with multiple firmwares and the driver fails to install. I just want a preamp / eq that works system wide, so I'm not tied to a specific audio player.)

Android Q V4A not processing with bluetooth

When I use V4A (2.7.1 form XDA Labs) with USB it works fine (also in speaker mode), but when I switch to use it with bluetooth it's not processing. Audio format is supported and status is normal.
I tried the "fixes" that solves the issues with USB but non of them worked:
Disable and enable "Master limit" in V4A, than stop music and start.​Force close V4A app, open it and start music.​Tried to pay music with Poweramp instead of YouTube but still nothing.
I also had this issue with the Beta 6 and now with the official release.
So does anyone know why it's not processing and how can I make it work?
Mines working.
Do you have the audio modification library in magisk, and is it enabled? If it is, disable it and reboot.

Thank you

Android DSP question.

Ever since I started using android, my choice for a DSP unit was Noozxoide EIZO-rewire™ PRO. Apparently, since the last update, the software is no longer usable. Lowering the volume only inserts a crappy stuttering sound. Since that app is old (but gold) and not updated, It seems it's finally time to move on. So, what are your takes on DSPs on Android Pie?
I need a module that does not require root or other methods of tampering with the system.
I need a module with profiles for each and every sound output (internal, jack and wireless).
I need it to auto-start on boot and work in the background without needing to set it up, or start it every time I want to use the music player or other media software.
The app mentioned above did everything I needed.
Thank you!
I'm afraid, there are no other rootless solutions for Android 8+. At least I don't know of any working one.

I tried the basic debugging solution... Idk what happened during the update but here goes my log:
>test game - volume slider working
>test youtube - volume slider working
>test sony music - volume slider creates audio glitching
>test google music - volume slider creates audio glitching
>force stop audio engine
>test sony music - volume slider creates audio glitching
>test google music - volume slider working
>force stop sony music
>test sony music - volume slider working
>reboot
>volume slider working globally
So that old but gold engine is still up for the task... Problem fixed,
UPDATE 2: problem occurring after system-wide back-up using the google back-up option. It seems it tampers with the normal operation of the integrated audio API. So, after a full back-up, a reboot and/or force restart of the DSP engine is needed. Also, sometimes after a reboot, the system is not operational again, then, the only fix is force stopping and restarting the process for the audio processor.
Will still keep an eye on the thread, maybe there are rootless solutions that could still work...
UPDATE 3. The problems persisted so I tried to access the Noozxoide EIZO-rewire™ PRO control panel from the music app (Sony Music Port - lastest version) and surprise, there was a new basic equalizer there that I never installed. It seems that Xiaomi pushed a new equalizer system to our phones that was interfering with my processor. I checked the system apps and found a new MusicFX app there. I disabled it and it seems everything is now working as intended.
The point is that for the past few days I tried to find an app that could replace EIZO, and no luck. There is no rootless system audio processor available, except those crappy riced apps from the store. So, if you want to get the most out of your audio, the solution was now found. This rootless mod almost gives you the sound quality you'll get from an iPhone 6s (mono speaker) and great sound from headphones/wireless devices.

Problem with sound on apps that transfer sound from PC

This is my first ever thread so I hope I'm doing this right. I've been using PixelExperience 12 (specifically PixelExperience_Plus_ginkgo-12.1-20220517-1915-OFFICIAL) and I have noticed an issue when using some apps (AudioRelay, SoundWire, moonlight game streaming) that transfer sound from PC. The problem is that the sound is hollow and slightly shifted to the right earpiece. Here are the steps to replicate my issue:
1. AudioRelay - Default settings will have the issue. Selecting "AudioTrack" and disabling "request low latency" fixes it.
2. SoundWire - Setting the "audio buffer size" in settings to 32k or lower will automatically switch to "native audio" in "android native audio" setting which causes the problem to happen. Switching back to "standard audio" fixes it.
3. Moonlight - The issue is always present and there is no way to around it.
I am just making an assumption here but this seems like a problem with low latency audio or something. I've also tried other android 12 ROMs like arrowOS and pixelOS and they have the same issue. Does anyone else have this problem?
