As has been said in another followup this is because of the new duplex
code (BTW I'm glad that full duplex is finally supported in the free
driver!). A simple workaround is to disable full duplex in the driver
source (patch for 2.1.129):

If you have a modularized sound driver you change the behaviour at
run-time.
A cleaner solution would be an ioctl on /dev/sndstat or some other
run-time configuration. Alan?
