Summary: surround40 memory leak
Description:
It seems that surround40 has a memory leak or somthing similar, playing a
game in surround40 mode the game result unplayable after some minutes.
And there is a problem in CS46xx.conf file, i need to remove the hook on
the rear pcm to permit multiple surround40 subdevices to be opened.

Yes it does.

I know it, but the volume control per PCM stream doesn't want to work,
maybe bitmage2 wants to try that patch and play blinded till he undestand
how scb manage these volumes.

It's possible i'll do some tests.

Well i'm working on a my implementation of openal
(dino.e4a.it/openal-alsa) and i've an unreleased version that can play
with surrond40(that works with an emu10k1) unfortunally, because of this
problems i can't use it :(
bye,

>> Yes! All the volume controls (front,rear,center,lfe) change the volume
of the correct channels. This is true for KMix
Do you mean KMix can handle those duplicate controls ( caused by 2 AC97 )
?
