A solution is found! But I'd like to understand why the other failed:
Wizard root # aplay -D hw:0,1 /home/mark/data/wave/seque~10.wav

And I get sound just fine...
Why is specifying the device required? As root I have no .asoundrc file,
but as a user I do:
pcm.via82xx {
type hw
card 0
}
ctl.via82xx {
type hw
card 0
}
Apparently my version is not new enough for your new option:
Wizard modules.d # /etc/init.d/alsasound restart
* Shutting down ALSA

* Initialising ALSA
* Starting sound driver: snd-via82xx Warning: ignoring dxs_support=2,

This process went on for most of the day. Later Saturday evening, following who knows how many 'unrelated' changes, Alsa stopped working.

I'll attach a bit of data, but can anyone point me toward what might be causing this? the chip looks like a VIA8235, so the (first) pcm device supports multiple playbacks but with the same sample rate. please check whether there is any other app running and using the pcm device and if it uses different sample rates (e.g. 48kHz)... Takashi Takashi-san, To the best of my knowledge there are no other apps using sound in any way. The environment is fluxbox, which doesn't use sound. I get the same results in a console after a cold boot before starting fluxbox also. I've tried playing 48KHz and 44.1KHz wave files and get the same results. There is a strange thing I noticed about how the chip is set up though. I've loaded the via82xx driver.
