Sound stops working after Hibernate

dScaler 3.1.0
Hauppauge WinTV 401
Epox 8K7A+ mainboard onboard audio
Win 2k Pro

After waking up from the Hibernate function in Win2k,
sound doesn't work when I load dScaler unless I:
a) Restart Windows
b) Load a previous version of dScaler (2.3.0) and
reload 3.1.0

Note: Sound works in every other application except
dScaler 3.1.0
