Hijacking ? Interesting word, but I think it applies to what I want to do...

In Windows, I was able to play an audio source, or even a DVD, and "hijack" the audio track to save as a WAV file. I have tried, and failed, to be able to do this in Linux/Knoppix.

First the background...
Knoppix HD Installed v 3.3
Sound card...
***** Input coming from an external stereo system.
***** Output going to both speakers on monitor, and an external stereo system.

All inputs and outputs have been tested, they worked as expected in Windows, and both the in, and outs, have been tested one-at-a-time, in Knoppix/Linux.

What I want to do:
I want to play a DVD, usually XINE, or play a CD, or cassette tape, from either stereo system, or from the internal computer device -=- and record (hijack) the audio to be saved within the computer system. Using the computer CDROM (audio) I usually use XMMS.

I tried XINE and Audacity - XINE worked fine playing, but Audacity yelled about the fact that the audio was locked by another source, and would not allow play, or record, within itself.

In Windows, I agree you can't play two sources at one time, only one source can have control of a output -=- but, Nothing had control of the RECORD side, and in Windows, I could get a audio program to "tap" the record side. It appears, with Audacity, this isn't the case. It wants both control of the Play, but also the Record.

Has anyone had any luck getting audio sources recorded while playing a source???

Thanks in advance...

BTW - My (side/hobby) business is providing AUDIO transcribing to CDROM - usually, customers provide a source on cassette tape (analog), and I take that source, as per customer requirements, and master a CDROM (digital) for them - complete with Liner notes, and labeling. If I can't get Knoppix/Linux to accept input and output from all sources, and still allow recording, I think my (personal) business is going to go under here. Thanks
