Hi.
I am quiet desperate...
'cause every HOWTO I found so far:
...unfortunatly covers only recording using btaudio / OSS!
...but as I heard that the OSS-sound-drivers (DEPRICATED) will be removed in
one of the next kernel releases, I am trying to use the new snd_bt87x /
saa7134_alsa ALSA-modules!
The /etc/asound.conf is "a book with seven seals" to me.
And the (for me) cryptical error messages from alsa (via mencoder) are not very
helpfull to me too.
Thats why any help would be VERY VERY apreciated!!!
...or if someone knows someone / or / a website that might help me on this...
Okey, here is my situation/problems:
///KERNEL///

( why: mencoder uses /dev/dsp to record from, but this belongs to my soundcard.
Ok the cinergy-tv-card (/dev/video1) has the audio-out-cable in the line-in of
my sound-card! AND it only worx, if I set the "record"-source/capture-source to
"Line" (e.g. via aumix) - nicely I don't hear the sound even if it recors, if I
put the sound-level to 0 within aumix for "line" even though the sound gets
recorded!)
