When I try to use my new USB TV tuner (Pinnacle PCTV USB2 PAL) on Fedora 14 (log messages: in the end) with this: mplayer -tv driver=v4l2:input=0:width=768:height=576:device=/dev/video2:norm=5:chanlist=europe-west:freq=224.25 tv:// I hear nothing, but I c good pictures... When I use this command simultaneously: parec --device=alsa_input.hw_1 > bla.raw I get correct audio with strong noise: http://www.wgboome.de./bla.wav (it is from input=1 for copyright reasons... so there is silence plus noise) according to "amixer -c1" (card 0 is the audio device on the mainboard and is handled by pulseaudio) the PCTV audio device has mono audio: Simple mixer control 'Line',0 Capabilities: cvolume cvolume-joined cswitch cswitch-joined penum Capture channels: Mono Limits: Capture 0 - 16 Mono: Capture 8 [50%] [0.00dB] [on] but arecord wants "-c2"... someone on linux media mailing list thinks, that somehow YUV data might get into the audio stream... Why is that? Thx.
