Red Hat Bugzilla – Bug 848810
Driver Failures with Terratec Phase 26
Last modified: 2012-08-29 15:19:27 EDT
Description of problem:
The Soundcard crashes every few hours and creates only noise on the outputs.
Also the Sound has many distrotions.
Version-Release number of selected component (if applicable):
The soundcard works more or less normally, but with distortions, but from time to time, when there is no music playing, the Soundcard-driver crashes and the soundcard creates noise with full level.
After disconnect the soundcard, reconnect and kill pulseaudio, the soundcard works normally, but with distortions, again.
The failure appeared around Mai in Fedora 16 and is also after upgrading to 17 still there.
dmesg-Output: disconnecting and connecting again:

Thanks for filing an issue. It's not obvious from the dmesg output or from some searching on the web that this sound card is indeed using firmware provided by the alsa-firmware package. What firmware is it using?
At this stage, there is not really enough information to help and since I don't have the hardware in question, I also can't attempt to reproduce it.
Please be aware that problems with sound can be caused by many different
software components within a Fedora system (including ALSA kernel modules,
PulseAudio, desktop volume controls, individual applications, firmware and more) and tracking down the problem closer would help to have a chance of getting it solved.
