I have a Asus Xonar Essence ST soundboard (Chip: AV200) I can choose between these analog outputs: stereo, headphones and front panel headphones. Sometimes from this list stereo disappears... So the headphones are enabled by default because stereo is not avaible. By restarting the computer everything returns ok. It does it since Fedora 14. 2.6.38.8-32.fc15.x86_64
I forgot to write that I use alsamixer to choose between these analog outputs
Sorry but this doesn't sound like a problem with alsa-tools. alsa-tools contains some specific tools for dealing with specialist sound cards only. 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 and more) and you may find it easier to get some informal help to track down the problem before filing bugs (if necessary), so that you can file them against the right component and the appropriate person can help. Help resources are listed here: http://fedoraproject.org/en/get-help If you still believe that your problem is with alsa-tools, please re-open this bug with further details. Alternatively, if you identify the software causing the problem, you could change the Component accordingly and re-open it.
