    sudden death of sound drivers


    I've been using FC6 on a P4 machine happily for some time now. I have *never* had any problems with the audio previously. Yesterday I turned off the computer. When I powered it back up, I attempted to use Amarok to listen to some music. It gave me the following error:

    xine was unable to initialize any audio drivers.

    This has never happend before. I checked to see if mythTV had sound. It didn't either. So for no apparent reason I have no sound. I tried googling the Amarok error, but didn't come up with anything helpful. Also, the ususal entry, intel<someotherstuff> is missing from kmix. At this point I'm not even sure how to troubleshoot this. ANY help is appreciated. Some outputs follow:

    relevent #lspci -v output:

    Red face Have you launching alsamixer?

    I am not really the strongest linux user so I may not be able to help you all that much but here goes; have you tried launching "alsamixer" <cr> in Bash? Once you do; you should be presented with a bunch of sound settings that can be toggled though with your arrow keys. The sound levels can also be adjusted with up or down arrow keys. Once your finished; hit the "escape" key and save your new settings by typing "alsactl store" <cr>. This is the most simple way to troubleshoot the problem. I really hope this helps! Good luck.

    solved

    Yea, In my incredible wisdom, I must have accidentally changed the IRQ the sound card was using in the system BIOS. I don't know how or why I would have done that, but changing the IRQ fix ed the problem. I'm my own worst enemy.
