Just running many more tests to try and provide more info for you. sorrydave.au plays at light speed as well on guspnp9; plays fine on Vox30 (current drivers). Here's a salient piece of info. On guspnp9 if I record a 8012Hz mono 8-bit sample via /dev/dsp that's 6.5 seconds long, I get a file that's 327k long instead of around 56k (simple record and play test code attached). If I play it also via guspnp9 it sounds fine. I think this is the underlying problem. Seems like /dev/audio and /dev/dsp are reading/writing bigger samples than they should. If I use the same code to record a 8012Hz mono 8-bit sample on Vox30, verify it plays fine on Vox30, verify the size makes sence, and then play it with guspnp9, I get light speed mice. Seems to confirm the sample size discrepency. BTW, in case it helps, I was able to play prerecorded 8000k/8012k .au's OK on guspnp7, so it's likely a recent change that's the culprit.
