I don't hear sound when I use ffmpeg. I hear sound if I use moTV (or one of the other above mantioned programs). The mixer settings are always the same: Mixer vol is currently set to 78:78 Mixer pcm is currently set to 88:88 Mixer speaker is currently set to 88:88 Mixer line is currently set to 82:82 Mixer mic is currently set to 92:92 Mixer cd is currently set to 90:90 Mixer rec is currently set to 81:81 Mixer ogain is currently set to 78:78 Mixer line1 is currently set to 90:90 Mixer phin is currently set to 90:90 Mixer phout is currently set to 84:84 Recording source: line Now I disconnected the audio output of the tv card from the input of the sound card and plugged the output of hifi cd player there instead. Now ffmpeg records sound (not from tv ofcourse but from the cd player). That tells me that the mixér settings are ok but the tv card does not send sound then I use ffmpeg (or nuppelvideo). -- Bye Frank
