Well that's one problem resolved. Any idea which soundcard it is playing

F8 comes with alsa driver 1.0.16, and as you have 1.0.18rc3, you obviously 
have no problems in upgrading the alsa driver. It may be worth upgrading to 
the latest snapshot of the alsa driver. Link below.

The codec above is for the onboard soundcard

The one above appears to be something to do with a sound component on the 
onboard graphics card, that also uses snd-hda-intel, and is to do with sound 
on HDMI.

Having only one soundcard (the onboard hda intel one), no doubt explains why I 
don't have the Multiselector click bar. I'll have to get hold of a cheap 
soundcard to add as a second card to this machine, and see if the 
Multiselector click bar turns up in Kmix. If nothing else it may be usefull 
in helping folks out that have more than one soundcard like you have.

The intel card isn't going to do what the audigy 2 one can. The audigy2 
(emu10k1) is capable of dealing with multiple audio streams, although Alsa's 
Dmix works around some of these problems so that you can play more than one 
app at the same time on non audigy (emu10k1) cards.

A while back I remember you saying that you were using skype with the onboard 
card, and the audigy card for other audio apps, and it was working fine. This 
I assume was on another PC. I may be wrong, but don't think the hda intel 
card on it's own is going to do this.

The question is. Can you now get access to both cards, so that you can select 
one or the other when using an audio app.
