I've just installed KDE on wheezy
as I have a black magic pro capture card and on gnome it kills all
user permissions
(Shutdown, eject cdrom, etc) but with KDE it works, go figure!!
but I've noticed the audio crackles and distorts when playing any audio
I've tried the inbuilt sound card and a sound blaster FX TI
Is there some setting that might fix this (other than removing pulse
audio as I need that)?
I don't know what output from the CLI to give to hints what might be wrong

AFAIK for PA issues it's more likely, that something completely doesn't

work.
Hard to say, where to start troubleshooting.
Does your sound card share an IRQ with your mouse or keyboard?
# cat /proc/interrupts
If we found out what's going wrong, there are a lot of things you could
do, or there's nothing you can do. Unfortunately I don't now much about
PA. Does it provide to use audio IOs of both cards at the same time? I
would disable one card and test what happens, if only one card is
enabled.

and the output is here http://paste.debian.net/6477/
and sadly it means nothing to me other than I recognize some hardware names
the sounds is mostly fine on this reinstall just when I use vlc or other
media players I get distortion, not cool when I want to watch a DVD
