Jozsa, You could try the mixer setting. I had to set mine to 2 to get it working. My modules.conf for the saa7134 is pre-install saa7134 modprobe -k tuner;modprobe -k tda9887 post-remove saa7134 modprobe -r tuner;modprobe -r tda9887 options saa7134 card=2 mixer_nr=2 Cheers, Barrie Hi, I'm glad it's not only me suffering with the flyvideo3k's sound problem. I'd like to mention an additional piece of info which *might* help debugging the problem. It's kinda voodoo right again, but is reproducable. I still don't get any sound when using from xawtv, but I do get proper sound from the tvcard following the steps: 1. modprobe saa7134 card=2 2. start xawtv, and exit 3. rmmod saa7134 4. modprobe saa7134 card=3 (yep, i know that's for flyvideo2k) At this point I hear the sound of the last tuned tv channel, but as soon as I start xawtv, the sound is gone right again. I were unable to get any sound while xawtv is running, nor with loading the saa7134 driver with the right settings for my card (card=2).. I'd do anything (ok, almost anything ;) to help track down this problem. If any developer could jump in debugging the problem, please mail me some instructions to try out on my config, I'll answer ASAP with the results. Best regards, Christopher Jozsa ps. my config is: gentoo linux, kernel 2.4.19 patched with gentoo stuff, v4l2 and saa7134 0.1.10 (i've tried the 3 previous driver versions as well) ps2. xawtv, sound from flyvideo3k still works on my old debian box without a hitch(!), so I guess the cabeling and mixer settings are correct
