Hi.

I have been struggling to record my soundcard's output in KDE4.

This is not distro specific as I have the same issue in Fedora, Arch, Pclinuxos..

This is also not any specific app it is all of them (I have tried)...

It used to work fine on all KDE3 distros...

In the KDE mixer I have the following options for input source
- Mic
- Front Mic
- Line
- CD

= none of these record soundcard.

As an example I am trying to record in Audacity - It doesn't matter what option I choose as the recording device - all I get is nothing or static.
The options I have are
- Default
- spdif
- HDA Nvidia :ACL888 Analog (hw0,0)
- HDA Nvidia :ACL888 Digital (hw0,1)
- HDA Nvidia :ACL888 Analog (hw0,2)

I am just trying to record my soundcard's output, not mic / line in - I have muted mic and linein - same.

Anyone got any ideas how to sort this out?

cheers

There are sound cards providing a "Mix" capture hardware device, but the HDA cards don't (like most other modern sound interfaces). The only option is to use software: jackd and jack enabled applications (audacity can use jack), or the alsa module snd-aloop.

Thank you for your advice.

Your mention of snd-aloop lead me in the right direction.

This article sums up what I had to do
