[alsa-devel] CS5530 on Geode GX1 won't work
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.

------------------------ 8<-------------------------
No one is using the sound device. But strace shows error 'Device or resource busy'. The thing that confuses me is the output of 'aplay -L'...
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?

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)?
