Capture PCM output of apulse about apulse

Got it working.

I noticed if I use sleep or usleep to prevent high cpu mainloop cycles, firefox stops processing more data which will result in empty callbacks too.

I managed to filter out normal underruns, but I need to find a way to clock/sleep inside the mainloop to keep the cpu usage low without thread blocking firefox internal buffer fill code.

So normal sleep or usleep functions do not work, because they prevent loading new data on firefox side.

Update 1:
So I found out, that the pa_threaded_mainloop gets locked and unlocked.
While we are inside "data_available_for_stream", the thread is locked as far I can see.
If the thread is locked and a sleep gets called, the sleep gets executed in the parent thread (which is firefox audio processing thread) instead of the current thread.
If I comment out all lock/unlock logic, sleep does work and firefox does always provide data.

But its a bad idea to disable all locking and unlocking logic, can someone tell me how I can sleep inside data_available_for_stream() while the thread is locked without sleeping in the firefox audio thread? I just want to sleep inside the mainloop thread.
