Hi Matt,
I didn't use a RME HDSP9632 for quite a long time (also I never used it
with the dmix plugin). However, the dmesg message sounds like a clock
source problem. All I can suggest is to check for the correct rate
settings, e.g. compare what hdspconf is showing to the output of
cat /proc/asound/card0/hdsp
--fe
