dxs_support detection or feature broken?

[John Gotts <jgotts@linuxsavvy.com>]

I have an ASUS A7V8X motherboard with a VIA VT8233 audio controller equipped
with SPDIF.  I have a set of digital speakers and use the SPDIF out for
everything possible.  (The speakers will fall back to analog if there is no
digital signal present.)

00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio Controller (rev 50)

For a long time (through 1.0.0rc1) I had been using plug:spdif as my audio
device and aplay had no problems playing 22,050 Hz WAV files:

aplay -D plug:spdif <filename>.wav

But with 1.0.1 my speakers started playing 22,050 Hz WAV files at 48,000 Hz.

After reading the following thread:

http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg10448.html

I added the following line to my /etc/modules.conf:

options snd-via82xx dxs_support=3

and plug:spdif is working again.  One message says "By default snd-via82xx uses
dxs_support=3 (except for certain known motherboards)."  Either my motherboard
should become unknown or this feature is not working correctly.
