14 | * | |
e5779998 DM |
15 | * - the linked URBs would be preferred but not used so far because of |
16 | * the instability of unlinking. | |
17 | * - type II is not supported properly. there is no device which supports | |
18 | * this type *correctly*. SB extigy looks as if it supports, but it's | |
19 | * indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream). | |
