[Alsa-user] According SB Live! 5.1 and analog 5.1 surround-system issue (noise from center)

[Johanson V. <ver...@fa...>]

Hello everyone,

I have Creative Sound Blaster Live! 5.1 Digital (Model #0220) installed
on my pc and Creative Inspire 5.1 5300 (analog) connected to soundcard.
Recently installed Slackware 9.1 (kernel 2.4.22, alsa 0.9.6). Just after
instalation on first boot have heard this bad ;) noise from center
speaker (just like if you enable a "digital output only" checkbox in
Creative Surround Mixer under windoze). Mutted "SB Live Analog/Digital
Output Jack" with alsamixer and did alsactl store. Noise gone. OK for
now. But everytime i've been booting, just after the kernel loads the
drivers, there was this noise again till the end of os loading (for about
4 sec) when /etc/rd.d/rc.alsa restores the alsamixer settings.

Did lots of searching/reading and finaly up to this time I have a
workaround of this problem.
On alsa.opensrc.org have found this note "Using alsactl to preserve
volume state"
(http://alsa.opensrc.org/index.php?page=Using+alsactl+to+preserve+volume+state),
so did exacly as said there - aded
those lines in my /etc/mudles.conf:

post-install snd-driver-name /usr/sbin/alsactl restore
pre-remove snd-driver-name /usr/sbin/alsactl store

After this during boot time center speaker emmits the noise just for a
hafl of second, but *it still does*. Frankly, i'm not happy with such
solution at all. In fact it drives me mad. It's this control thing: like
many of us i want to have control of my machine, total obedience, so i
want it to emitt any sound only then i want it to do so (and certainly
not sound like this).

So my question would be: is there any way to get rid of the noise at all?
Maybe somehow to disable the digital output in the driver itself, or
compile it this way, or put something in certain configuration file? Did
i miss something when reading the documentation/howtos/forums? (three
questions, actually ;)

Best regards,
Johanson Vertrygen

PS: hmm... wasn't the message redundand? ;)
