Description Jan Willies 2009-07-01 09:20:02 UTC
Description of problem: Whenever I switch the sound from internal soundcard to the usb-card, there's just noise coming out of the speakers. Internal works fine though. I'm using the digital output (SPDIF)


Version-Release number of selected component (if applicable): 0.9.15-14.fc11


How reproducible: always


Steps to Reproduce:
1. attach USB-card
2. play music
3. switch from internal to usb-card
  
Actual results: loud noise 


Expected results: music


Additional info: It worked well with F10. 
The output of alsa-info can be found here: http://www.alsa-project.org/db/?f=947470708990d306b5c804c95cc690226c9fb96e
Also, sometimes there's lots of "ALSA sound/usb/usbaudio.c:354: frame 0 active: -71" in /var/log/messages when attaching the usb-soundcard.

what happens if you play audio through aplay?

aplay -f CD -D spdif:xxxx < /dev/urandom

(where xxx is the card index/name)

does that work?

Comment 2 Jan Willies 2009-07-05 12:53:03 UTC
magically works now. there's some initial noise though, while switching, but the card plays after a few secs fine.

thanks for the fast response, please close this ticket
