Public bug reported:
Binary package hint: linux-image-2.6.22-14-rt
I have a Terratec Phase 26 USB soundcard, which worked fine under feisty
and edgy. WIth the updated to Gutsy I experience a crash whenever an
application tries to play sound with this soundcard.
One example:
1. I open gnome-sound-properties
2. select USB-Audio
3. click on test
Result: immediate Segmentation fault
I could reproduce this using the same sound card on a friend's notebook
(an IBM modell, I have got a Samsung X-10). Tested it with this kernel
2.6.22-14-rt #1 SMP PREEMPT RT Mon Oct 15 01:05:51 GMT 2007 i686
GNU/Linux, as well als the non -rt one.
I am not fully sure if this is related, but dmesg outputs this:
