C-Media CMI8738 PCI sound card

Hi All

I had extremely problems with freezes with my X5000 last days. I figured out that my C-Media CMI8738 PCI sound card is the problem.

I removed this sound card and afterwards these error messages and the freezes are gone. The strange thing is, that I don't have any problems with this card in my AmigaOne X1000.

I bought the Vivanco USB sound card with the CM108 audio controller yesterday. It works fantastic with my X5000.

Cheers

Running Linux on AmigaONEs can require some tinkering.
