[Pkg-alsa-devel] Bug#517675: alsa-base: alsa won't work properly with snd-usb-audio after upgrade to lenny

[Johannes Wiedersich]

Package: alsa-base
Version: 1.0.17.dfsg-4
Severity: important

Following an upgrade to lenny, my 'terratec phase 26 usb' sound card is no longer fully supported by debian. 
This card features a switch to change the bit level and frequency of the card. On etch it works fine with all 
settings, on lenny only with the lowest quality setting of 16/48. 

Setting the card, eg. to 24/48 leads to the following segmentation fault: 

$ aplay -l

Segmentation fault

The card will work on 16/48, but it is little use having a high quality sound card, if only the lowest quality 
is supported. The card is reported to work fine with alsa's upstream code. 

Cheers, 
Johannes
