I have the same (onboard + hdmi + webcam) and it seemed like the order was random every time I rebooted, and I had to reconfigure all my things that use sound. Fixing the order to be the same every time helped to solve that problem. For mplayer you can force the output to use the proper device in your mplayer.conf Use alsamixer to enable/disable the inputs depending on when you are using them. Maybe your microphone is recording and played back when you watch TV, causing the bad sounds... it's only a guess. :) For testing it might be easier to use aplay and arecord (from media-sound/alsa-utils) since they give you a more explicit choice of ALSA devices. For example "aplay -l" will list your playback devices, "arecord -l" will list the input devices. Then you can experiment with them and alsamixer until you find which one works. The alsa-info script will give you all the info about your sound hardware. Probably more info than you care about knowing. :) Good luck, Paul
