Description quentin.denis 2014-08-01 07:41:02 UTC

Hi all,

My USB soundcard (Bose companion 5) works well on my running system. However, as soon as I suspend my system and resume, pulseaudio will not recognize my card. Even if I unplug and replug.

Executing "$ /usr/bin/pasuspender /bin/true" will not help. The only workaround is to kill the pulseaudio process and let it autorestart (which unfortunate will break my audio/video players running).

How can I make sure my USB sound remains properly alive after suspend?

Regards,
Quentin

without more evidence, I'd suspect your kernel/device-driver (not handling suspending) before pulseaudio

How do you suggest to get more evidence?

My system recognized the device when I (re)plug it:

The only issue is pulseaudio not connecting the device (pavucontrol even does not show it in the configuration tab).

do the sound car suspend and resume without pulseaudio ?

perform suspend and resume while playing your USB directly through alsa hw device

aplay -D hw:CARD=Bose  any.wav

This may also be a duplicate of bug 54029 - hard to tell without any logs.
