I prefer xine, as I've had better luck with it accepting whatever media I 
throw at it.  However, modern Kaffeine doesn't use Xine, it uses Phonon.  My 
local Phonon uses Xine.

I'm fine with not using Kaffeine, but I would like to continue using Phonon.  
Dragon would be fine if it would let me queue up an entire season of M*A*S*H, 
for example.

No.  It's not installed.  Jack is, and that gives me a new Phonon device, but 
it is set to low preference.

Yes.  Kaffeine itself is not muted, and dragging the volume slider changes 
nothing.

Xine.

I can try that, but I don't think this is an Phonon issue.  I think it is a 
Kaffeine issue.  Dragon player uses Phonon and sound works perfectly in it.

I've never gotten those messages, except for when I removed Audio hardware.  
That hasn't happened recently.

Already did that.  When I was testing / prioritizing devices I was on the 
"Games" role.  After I got that working, I applied it to all the other audio 
output roles.

I have a high-end sound card that does hardware mixing so /dev/dsp (for 
example) can be opened up to 32 times concurrently.  However, Kaffeine uses 
Phonon now (very few settings to change in my Kaffeine) so I wouldn't expect 
that to be a problem.  Even if Phonon doesn't hide such issues, I'm already 
set up for mixing; Amarok, Dragon, and event-triggered sounds can all play at 
once, though it makes quite a cacophony.

I'm not at the computer in question, but I'll try another Phonon back-end when 
I get back to it and report back at that time.

Thanks for the reply.
