Hi Jonathan,
thank you very much for taking your time to look at my problem.
I applied your patch and rebuild the kernel. Unfortunately I still have
no sound on the iMac.
BTW: I didn't explicitly mention if but I am using -current (amd64).
With the i386-version there was no sound either.
If I can provide any other info on the system please let me know.
All the best,
STEFAN
