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: ..
