Quote from:
High Definition Audio Specification 1.0a, section 3.3.35

Offset 80: {IOB}SDnCTL Stream Reset (SRST): Writing a 1 causes
the corresponding stream to be reset. The Stream Descriptor
registers (except the SRST bit itself) ... are reset.

Change the code to reset the Stream Descriptor Control and Status
registers except the SRST bit.
