[-- Attachment #1 --] Amancio Hasty: |Does this happen the first time or always? |Do you happen to know at what frequency was james-earl-jones-CNN.au |recorded at? | |From The Desk Of Randall Hopper : |> cat james-earl-jones-CNN.au > /dev/audio |> |> this 5 second clip flies by in less than one second! :-) The frequency is |If you can't find au file which has been recorded at 8khz , |feel free to download : |ftp://rah.star-gate.com/pub/sorrydave.au Thanks, I had one. 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.
