Okay. The thing that "fixed" Tyson was disabling mmap from the driver:

I'll be trying that just a little later today, as in, sometime in the next half hour or so.
It landed him in the same situation as you though, where that "asskickd.wav" mono, 8-bit 11025 file you sent me shows the same behaviour you reported. This might imply you weren't using mmap to begin with. You have no horribly obsolete alsa userland, nor an /etc/asound.conf or ~/.asoundrc?
I don't have either of the two files mentioned above. As far as the alsa userland, I would think it's all "reasonably" current. I'm running Debian "Etch" fully patched/updated. I'll normally refrain from running things in the "unstable" or "experimental" categories unless something is broken in the "stable" tree that isn't getting fixed (e.g., a libc problem). Beyond that, I also tend to run the latest kernels to make sure we (the community) get an early warning if there are problems with kernel updates/changes on the Alpha architecture. Because it's a reasonably small list, here is the relevant "dpkg -l" output for alsa packages:
Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==================================-====================================-================================================================ ii alsa-base 1.0.13-5etch1 ALSA driver configuration files ii alsa-oss 1.0.12-1 ALSA wrapper for OSS applications ii alsa-utils 1.0.13-2 ALSA utilities ii alsaplayer-alsa 0.99.76-9 PCM player designed for ALSA (ALSA output module) ii alsaplayer-common 0.99.76-9 PCM player designed for ALSA (common files) ii alsaplayer-esd 0.99.76-9 PCM player designed for ALSA (EsounD output module) ii alsaplayer-gtk 0.99.76-9 PCM player designed for ALSA (GTK version) ii gstreamer0.10-alsa 0.10.10-4 GStreamer plugin for ALSA ii libasound2 1.0.13-2 ALSA library ii linux-sound-base 1.0.13-5etch1 base package for ALSA and OSS sound systems
No change with "aplay -M"? (and) This one needs answer so as to possibly pin things down to format:

Reported on the results of the various "sox" tests in that article last night.
For all of the above, I need to mention I am/was running an unpatched 2.6.25-rc7 kernel. "cat /proc/interrupts" shows absolutely no interrupt activity for the ES1888. Here's the current and complete output for an uptime of 1 day, 14:14:

Ok. Let me boot on the kernel with the "miata_no_mmap" patch and give that a spin. I'll report back shortly.
