well, yes, if creative follows the usb specification...
but i once heard that extigy works with OSS audio driver, so it likely

Hi,
I've exectly the same problem. When I use cat /usr/kde/3/hare/sounds/pop.wav
/dev/dsp, I get a I/O write error. The only thing that works is playing a
CD, I can mute/unmute, set the volume via alsamixer etc.
Bye,
Niek.

could you check whether the status in /proc/interrupts is changed
during playback?
also, could you check whether capture works? capture uses a different
SGD, so it might work

Just a thought.
That new info from lsusb could be because I just upgraded my jernel from
2.4.16 to 2.4.19-pre9. Nodoubt there was a lot of additions to the usb
code during the past 5 months.

most of pci drivers use a linear contigous buffer for pcm (per
stream).

Sorry,
forgot to mention, that I cannot check the status of the interrupt, because
there are other devices on the same interrupt (NIC and SCSI-adapter). I
could not find an option in my bios to give the audio chip an own interrupt.

I tried to measure the interrupts. Here are the results:
If I don't play sounds, I have about 1 interrupt/sec on interrupt 11.
If I play a mp3 with mpg321 (44,1kHz, 16bit), I get about 1375
interrupts/sec.
All values are measured after initializing the chip with oss-module,

there is a runtime instance for a pcm stream, and this holds the
informaton such as the current rate, channels, formats, etc.
there is no pitch parameter implemented in alsa, but this can be added
easily into the runtime instance, if inevitablly necessary.

it seems that USB audio supports 24 bit sample in 3 bytes format.
and additionally i've found there are 20bit and 18bit sample formats.
the world is large...
an arising problem is that the number of formats is limited to 32.
already 26 format types are used. the rest are only 6, and not
are formats currently a bit in a 'supported formats' flag?
