This timeout implies that the communication betweeen the codec and the
controller chips get broken.  The driver itself works fine with many
other devices, so it's likely another problem - in most cases, it's
either an ACPI problem or a conflict with non-working modem codec.   
The latter case is found, for example, on Thinkpad T60/X60.  If you
have a modem codec (see /proc/asound/card0/codec#*), try to exclude
the modem codec via probe_mask module option.
