xdm breaks sound

I have sound working fine until I launch xdm.
Then I no longer can get any sound until a reboot.
I started seeing this about a month ago,
but never had the time to report.

I see lots of:

hdac0: Unexpected unsolicited response from address 0: 0000000f

on the console.

I set hw.snd.verbose=4, and now I'm lost
in the logs, see below.

Please advise

Many thanks
