Hmm, I tried this but I can't reproduce the problem on my Libretto
(MMX 166MHz, audio chip revision 5 ("audioctl version" output)).

Can anyone reproduce this problem?

One possibility is that the calibration of CODEC is timed out.
Does it change if you modify magic constants (100, 10000 etc) in
	sys/dev/ic/ad1848.c::wait_for_calibration()
	sys/dev/ic/ad1848.c::ad1848_commit_settings()
or somewhere?
