[Alsa-user] Terratec Aureon Space 7.1 two sets of speakers (analogic AND digital)

[Alessandro <ale...@av...>]

Dear friend, 
I have a Terratec Aureon Space 7.1 and two sets of speakers connected to 
analogic AND digital spdif card exit. 

(FIRST)
With Mandrake 10.0 (Alsa 1.0.2) I can  play with the first or the latter set 
of speakers just changing (with a small script) the pcm.dmixer definition 
given below (pcm "hw:0,0" -> pcm "hw:0,1"). 

With Mandrake 10.1 (Alsa 1.0.6) I cannot play any sound with hw:0,0 (analogic) 
at all. I made many tests without any success. [I have the same behaviour 
with Arts (that I configure with Mandrake Control Center / Sound / Sound 
System / enable artds / hardware / select the audio device = OSS / override 
device location = /dev/sound/dsp or /dev/dsp)]

When I execute aplay -D default file.wav 
I obtain "Playing WAVE 'file.wav' : Signed 16 bit Little Endian, Rate 44100 
Hz, Stereo" but no sound. 

Alsamixer shows that volume is ok. 
Is this a bug?

I compared the code of ice1724.c and ice1724.conf (version 1.0.2 and 1.0.8) 
and they are indeed different but I'm not able to understand anything else. 
I've not yet decided to upgrade to 1.0.8. Is enough to follow the 
instructions on http://alsa.opensrc.org/index.php?page=AlsaBuild2.6 ? 

(SECOND)
Doing my attempts to understand what is going on I discovered two other 
strange things. 
cat /proc/asound/{version,cards,devices,hwdep,pcm} and 
cat /proc/asound/oss/sndstat
go loop (they never stop their output onto the screen). 
Ideas? Are the two things connected?
