This happen if no pulseaudio card profile is selected.

[hellmind]

Also im having crash if I use pulseaudio, , it seems mic cant be used with pulse.
I can select it but afte some tx It crash

SOUNDIO works "fine", but on rx i notice some weird noises

[daneenjah]

I'm having the same issue as well, ended up selling my ANON 7000 because of it.

[hellmind]

This is a problem about pulseaudio and buffer overflow. I must learn how to use those libs to discover where exactly is the bug. I think the problems is that buffer size isn't calculated correctly using every current variables as sample rate.

I have found the reason for this crash. When the mic is enabled, both data coming from the ANAN built-in mic port and from pulseaudio are processed. This of course is not only wrong, it also leads to a race condition, since processing protocol 2 data and processing audio data happens in the same thread. Thus, when process_mic_data is being run simultaneously in both threads, it can happen that one thread fills the buffer up, and before it can reset the buffer, the other thread adds to it overwriting the data.

I'll propose a fix.

BTW, to find the problem, I used clang as a compiler, and -fsanitize=address as build option. This pointed me to process_mic_data as the function overflowing its buffer. The rest was deduction.
