[Pkg-alsa-devel] Bug#912921: libasound2-plugins: Crashes pulseaudio

[Thomas Luzat]

Similar experience her, starting with 1.1.7-1. Downgrading to 1.1.6-1 helps.

My device is a Steinberg UR22 mkII. The pulseaudio log ends with:

I: [pulseaudio] alsa-util.c: Device iec958:4 doesn't support sample format
s16le, changed to s32le.
I: [pulseaudio] (alsa-lib)control.c: Invalid CTL iec958:4
I: [pulseaudio] alsa-util.c: Unable to attach to mixer iec958:4: No such
file or directory
I: [pulseaudio] alsa-util.c: Successfully attached to mixer 'hw:4'
I: [pulseaudio] alsa-util.c: Device front:4 doesn't support sample format
s16le, changed to s32le.
I: [pulseaudio] alsa-util.c: Device iec958:4 doesn't support sample format
s16le, changed to s32le.
I: [pulseaudio] (alsa-lib)pcm_a52.c: Cannot get slave hw_params

And a "pulseaudio" backtrace after the segmentation fault gives a
consistent:
