| 23 | * TODO: |
| 24 | * Do we need to take care of CCS register? |
| 25 | * Maybe we could use finer grained locking (separate locks for pb/cap)? |
| 26 | * Wishlist: |
| 27 | * Control Interface (mixer) support |
| 28 | * Better AC97 support (VSR...)? |
| 29 | * PM support |
| 30 | * MIDI support |
| 31 | * Game Port support |
| 32 | * SG DMA support (this will need *alot* of work) |
