line-out of my tv tuner card in the line-in of my onboard via soundcard, i can hear audio while
watching tv, and capture also used to work, but i haven'tt used it iin a while and now it does not
work, here is some info about my sound conf:

i don't know how to get it working, also I would like to know how my sounds devices and my tv
tuner card are called in the form of '/dev/XYZ' i know my tvcad (the video part) is on /dev/video0
so much is for sure, i also know that mostly sound is on /dev/dsp, but this is not for sure on my
system is there a command which gives me a list of my devices int he form of '/dev/XYZ' so i will
know for sure? and how the hell do i get to capture the sound from my tv tuner, i don't care if i
have to capture it directly from the bt878 or from the line in of one of my soundcards, i have
treid lots of things without success, i have also tried this
