Absent any guidance, I tried installing the alsa cvs on a different
machine with a different sound card. I must be doing something very
dumb, because I get the exact same xrun error.
Toshiba Tecra 8100, ymfpci sound, RedHat 7.2 upgraded to
kernel-2.4.9-13
Abit BP0-6, ens1371 sound, RedHat 7.2 upgraded to kernel-2.4.9-13smp.
In both cases, compile and install alsa-driver, alsa-libs, and
alsa-utils from the current cvs distribution, run snddevices, modify
/etc/modules.conf, install /etc/init.d/alsasound, chkconfig alsasound
on, reboot, alsasound starts okay, /var/log/messages says it starts
okay, /sbin/lsmod shows the driver is loaded and active,
/proc/asound/cards lists the card, /proc/asound/sndstat lists the card
and its capabilities, alsamixer finds the card and allows me to unmute
and raise volume, but no sound (*with two exceptions) and

One exception is that unmuting the only IEC958 channel on the
ens1371 puts a hiss on the speakers and the very start of
startup1.wave when its played.
The other exception is that the ymfpci can feed the internal
speakers back into the internal microphone with appropriate mixer
settings.
So what's wrong with this picture?

Patch to alsa-driver/INSTALL to bring cvs compile instructions up to
date with the cvscompile script and to remove the last of the
obsolesced snd-card-foo references:
