(1) Using the sox-based "play" command to play a short ".wav" file results in the file being played approx. 1.5 times, i.e., it plays all the way through, then restarts from the beginning and quits somewhere in the middle of the second playback. At least the sound doesn't seem distorted...

(2) Using "mpg123" results in silence at first, then after about 30 seconds, a tight loop of random repeating sound (doesn't sound like part of the mp3 file, but it's probably derived from it :-)) until the process is forcibly killed.

Sounds like a DMA screwup. However, I'm pretty sure that it's not a generic ALSA problem with ISA DMA, as my good old GUS MAX still works perfectly on lx164 (machine that is very similar to your miata) as I checked yesterday with patched 2.6.25-rc4. :-)

I have to hit <ctrl>C twice to interrupt playback.

/proc/asound/cards looks normal:

0 [ES1888 ]: ES1888 - ESS AudioDrive ES1888 ESS AudioDrive ES1888 at 0x220, irq 5, dma1 1, dma2 5

I wonder if it still works on x86 - perhaps you ought to ask ALSA folks. I'll search my machine room next week - I recall that there were a dozen of old ISA soundcards, maybe there is some es18xx stuff, but chances are slim...

Missed the original mssage, adding alsa-devel. I have a few dozen es18xx's cards but no Alpha's. Am compiling a 2.6.25-rc4 onto an x86 test box now.
