I have pulseaudio 1:0.9.14-0ubuntu20.1 installed, and I still
experience PA problems. Whenever there is high CPU load (compiling
something, ...), My music stops, I hear only crackling noises and I see
these messages:
D: alsa-util.c: snd_pcm_avail_update() returned a value that is exceptionally
large: 4611686018037680368 bytes (139430435728 ms) Most likely this is a Linux
bug. Please report this issue to the ALSA developers.
