Hello,

I would like to record Radio (TV is not very important) directly from
the TV-Card without passing the Sound through my Soundcard first.
Normally (with PCI-Soundcards) have have to connect Analog Audio OUT of
the TV-Card with a cable to Analog IN of your soundcard and additionally
the mixer settings of my soundcard have to be right to hear anything at all.

Which TV-Card is supported by ALSA to do this?
Or:
Where can I find information about which cards are supported to do this
by ALSA?

It would be great if it is a hybrid card that supports FM- as well als
DVB-T.

At present I own an WinTV PCI Card (PAL - B/G - I 61344 REV D421) and
direct Audio Recording doesn't work with ALSA:

In the meantime a record for my WinTV PCI-Card is shown at
/proc/asound/cards but trying to access /dev/snd/pcmC1D1c with sox

sox -V -r 48000 -w -t alsa /dev/snd/pcmC1D1c -t cdr test.wav

gives this error:

ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM /dev/snd/pcmC1D1c
sox: Failed reading /dev/snd/pcmC1D1c: cannot open audio device
