Ok. With my sound problem I did this and it had no effect. The only way I can get sound to come out is directly via the output jack on the flyvideo card and only by starting the radio program up?? I made a further observation: 1. Starting xawtv (flyvideo3000) under gnome window manager there is no sound 2. Starting xawtv (flyvideo3000) under straight X (# X & export DISPLAY=localhost:0.0; sleep 2; xawtv) there is no sound. 2. Starting the radio turns on the sound (out of the audio jack) 3. Changing the channel turns the sound back off 4. Switching to command line session (CTRL-ALT-F1) leaves sound on, but switching back to GUI (CTRL-ALT-F7) turns sound off. This is all sound coming directly out of the FlyVideo audio jack. 5. insmod saa7314 card=3 (for flyvideo2000 when I have flyvideo3000) turns the sound on immediately in the same fashion as starting "radio" but starting xawtv returns static and untunable channels. --Geoff
