Oh, I see now. Thank you very much for explaining that.

Now, when I do put in an option into the modules.conf specifying a different
dxs mode, am I still supposed to get the same message in my syslog about
picking trying dxs=1 or 4 or does that message show up only when no options
have been successfully parsed?

I am asking this since even when I am 100% sure that my syntax is/was ok I
would still get the message no matter what option was specified in
modules.conf. I tried hacking via82xx.c file where I would hardwire my
vendor/card ID into the list of known cards and changing it that way and the
card worked the same no matter which options I chose, so I decided to leave
it at DXS_ENABLE (or 1 if I am not mistaken). This is the only way how I
would disable that message from appearing in syslog.

What kind of difference am I supposed to notice by changing dxs in order to
figure out the best option anyhow?

As it is right now I can play 4 simultaneous streams and they all sound ok
(no apparent glitches etc.). But this is the case no matter which option I
pick.

No, I am working with 2.6.3 and 2.6.5 (both patched).

Finally, I've observed one extremely interesting phenomenon. I did notice
that when compiling preemptive versions of these kernels that I get tons of
xruns even when using aplay talking directly to hw:0. I literally need at
least buffer of 512 for aplay to play ok. I also noticed that certain
applications (i.e. frozen-bubble) would play stuff a bit faster than they
ought to be played (although I am not sure whether this is linked to a
particular alsa driver version or the preempt stuff).

With preemptive flag disabled, everything seems to be ok. 

Best wishes,

Ico
