Unsolved important bugs​

As I figured out, we are discussing about two bugs, both related with call sound. So let's clarify and seperate this things and give them names. I did systemtic testing on last build (may 2023) with gapps and installed with TWRP patch for remove mixer reiryuki / AOSP-soundfx-Remover as sugested @vlad9210

I grabbed log files with help of this tutorial. Sorry but I can't get the last_kmsg, any instruction will be welcome, specific for galaxy s8 please. Exact step by step guide how to save kmsg.

Added are also bug reports from android developer options menu. All provided logs/bug reports are captured right after bug happen.

bug 1: No call sound, you not hear other person​

I have not found the mechanism, what triggers this bug. I would say for now, it appers randomly, you never know when.

Soundfx Remover didn't help me at all. I installed patch with TWRP and then I carried out testing. My bluetooth handset was included.

So when this bug hits you, there is no sound in active call. From beginning on no sound during call. I tried swiching between phone/loudspeker/bloetooth handset. It's always the same - no sound. I noticed white noise in bluetooth handset, so this indicates that something regarding sound is happening in background otherwise will be complete silence (without noise).

You can play offline music, hear online radio, everything. All this can I normally hear in my bluetooth handset, but when I make a call or answer an incomming call, music player pause (just normal behavior) but in active call is no sound (only white noise in my bluettoth handset). After hang up music play on as were nothing wrong.

This is NOT sequence that trigers the bug. I just want to show that affect only calling.

As I tested on previous monts' builds, doesn't matter if you have rom with gapps or without them. The same is if you use stock dialer or google dialer.

2 Bug: Volume adjusting and mute not working in active call​

I extend this testing with bluetooth handset on may 2023 build. This time with removed mixer (reiryuki / AOSP-soundfx-Remover ).

This bug is extremely easy to reproduce! Every time you put call on speaker trigers this bug (no bluetooth handset connected). Or if you have connected bluetooth handset also trigers this bug.

Once you triger this bug (put call on speaker or connect bluetooth handset), you loose volume controll and mute function desn't work anymore. Reboot heal this.

Mute doesn't work on speaker, ear phone or bluetooth handset.

Volume adjust doesn't work on speaker, ear phone. For curiosity I tested on wired headphone and is the same. Suprisingly on bluetooth handsed I'm allways able to change volume.

Apart from donations, how else can I help? Or anyone else to contribute, that bug fix arrive in reasonable time? Consider that I'm not anykind of programmer, but I'm seeking for solution - bug fix! For me are both very important, and prevent me from daily usage of galaxy s8 phone.

I think it's time when developer @Ivan_Meler can step in. Danke voraus!
