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.

Raymond, this is about your question "Do you mean KMix can handle those
duplicate controls ( created by TWO AC97 ) ?".
I presume youre talking about those controls with index 1 (opposed to
index 0), right?
Honestly, I have no idea when those duplicate controls are uses. The only
thing I can say is this: I got all those duplicated devices (like PCM.0,
PCM.1 and Master.0, Master.1). And when I change the device state (volume,
capture ore playback switch) the change is reflected in alsamixer (and
vice versa).
For testing I tried to play back more than 32 channels via speaker-test .
I did this for checking whether channels 33 and above would go on the
second AC97. But ...
1) The channels above 32 just produce nonsense sounds (short, looping
sounds)
2) The volume of the nonsense soundss could not be controlled (not by
KMix, and also not by alsamixer)

Raymond, this is about your question "How about 'DAC Playback Volume' [...]
Does it control the volume of all the playback channels ?"
Card: Sound Fusion CS46xx
Chip: Cirrus Logic CS4294 rev 5,Cirrus Logic CS4294 rev 5,Cirrus
ALSA (lib,driver,everything): 1.0.9b
Answer: No, the 'DAC Playback Volume' only works on Front (aka Master) and
Rear. It does not have any effect on Center and LFE.
