Problem with sound cannot record


I have got suse 11.1 running on an AMD system (triple core). The sound card is internal, the chipset is supposed to be realtek “high definition audio”. In KMIX it shows “HDA ATI SB”.

I would like to record the sound that is played. On my laptop this was easy, I just had to click on a switch “output mix” or “loop back” or so and I could record the PCM sound that was played.

Now I don’t find any solution anymore. I can capture sound from mic, line and aux (whatever this is) and not from the output itself.

Any hints how to work around this ?
