Hi Frank,

works perfect here.

04:00.0 Multimedia audio controller: C-Media Electronics Inc CMI8788
[Oxygen HD Audio]
        Subsystem: ASUSTeK Computer Inc. Virtuoso 100 (Xonar D1)
        Flags: bus master, medium devsel, latency 32, IRQ 20
        I/O ports at d000 [size=256]
        Capabilities: [c0] Power Management version 2
        Kernel driver in use: AV200

I have compiled everything in the kernel, no modules.

Curious: why aren't you using udev?

Regards,

Martin
