Hello
As Alsa-User mailinglist could not help, I hopefully sent my mail to this list
now.
I am playing around, trying to get this sound card working for a while now.
The Hardware is an embedded Geode GX1. Kernel is vanilla 2.6.25.9.
Problem:
------------------------ 8<-------------------------

No one is using the sound device. But strace shows error 'Device or resource

Any help is appreciated :-)...

It's possible that the device has been opened with OSS (i.e., /dev/dsp*)
or that somebody has opened the capture device (SB doesn't do full
duplex). Is there anything in /dev/ that is being used?

Clemens

OSS is completely disabled in kernel .config.
Here is a complete grep on /dev:

Thank you for your help!
Any further suggestions?

As the sb16 is fully emulated on Geode GX1/CS5530 based systems, it could also
be a bug in the system management code (SMM or VSA)?
