Hi Nik,

This might be wrong, trying to remember from several years ago :(

Try one (or all) of these:

- Start KMix
- Left click on the KMix speaker icon in the task bar
- Click Select Master Chanel
- Set Current Mixer = [PulseAudio] or [the sound card you want]

If you chose PulseAudio then configure it:

- Open Pulse Audio Volume Control
- In Output Devises "Set as Fallback" (check icon) the sound card you want to 
use
- then when an app ignores that, start the app* and
- - in Playback select the sound card

* Apps only show up in Playback when they are running, such a pita...

Hopefully that'll give you enough direction to solve what you need?

Best,
Michael
