When I try to use my new USB TV tuner (Pinnacle PCTV USB2 PAL) on Fedora 14 (log
messages: in the end)
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...
