Terratec Phase 88 has two Selector Function Blocks of AVC Audio subunit to switch source of clock. One is to switch internal/external for the source and another is to switch word/spdif for the external clock. The IDs for these Selector Function Blocks are 9 and 8. But in current implementation they're 0 and 0.
