Strange emu10k1 behaviour on 2.4.9

Strange emu10k1 behaviour on 2.4.9

[Mike Frisch]

I have the emu10k1 support compiled as a module for 2.4.9.  When I use
the sound card, I have to adjust the volume or open the mixer for the
sound to actually start.  As soon as that program stops using the sound
card, the sound is turned off again.  It's not the volume level that
changes, but actually the sound is disabled or muted.

I have the following in /etc/modules.conf (as configured by 'sndconfig'
in RedHat 7.1):

alias sound-slot-0 emu10k1
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L \
   >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S \
 >/dev/null 2>&1 || :

lspci -v shows:

00:0d.0 Multimedia audio controller: Creative Labs SB Live! EMU10000

        Subsystem: Creative Labs CT4832 SBLive! Value

lsmod shows:

soundcore               4144   4  (autoclean) [emu10k1]

If I use the latest ALSA driver, everything works fine (although I don't
think the sound quality is as good).

System: ASUS A7A266, AMD T-Bird 1.2/266, 256MB Crucial DDR, Intel EEPro

Is is anybody else experiencing this problem?

Any assistance is appreciated.

Thanks,

Mike.
