Description

Created attachment 120880 .asoundrc used to enable the ALSA a52 plugin (only alsa conf used)

So I enabled the ALSA a52 plugin with the attached .asoundrc. PulseAudio starts fine and set up profile for it automatically. However, when I switch to the profile, Pulse throws an error and core dumped: E: [alsa-sink-a52:0] alsa-sink.c: Assertion 'frames > 0' failed at modules/alsa/alsa-sink.c:627, function mmap_write(). Aborting.
