phys_io
This is used to pre-select the source taken into a matrix input or the
destination to which an output is sent. Values can be selected from embedded
channel pairs or from separate physical AES streams. Value 0x20 selects
embedded channel pair 1. 0x27 selects channel pair 8. 0x28 selects the
associated AES stream.
Note: On IS2, there is no audio de-embedding function on the SDI Fill
input path number.
This is the number of the input or output as though it was a mono mixer.
Alternatively, the input may be thought of as the stereo input number
followed by a one bit left/right identifier, with Left being numerically lower
than Right.
The value is computed as 0x20 + path number:
0 0 1 0 0 0 0 0
+ 0 0 n n n n n p
nnnnn = STEREO input number
p = 0 Left
p = 1 Right
0x20 -> path 0 pair 1 LEFT
0x21 -> path 1 pair 1 RIGHT
0x22 -> path 2 pair 2 LEFT
0x23 -> path 3 pair 2 RIGHT
0x24 -> path 4 pair 3 LEFT
0x25 -> path 5 pair 3 RIGHT
0x26 -> path 6 pair 4 LEFT
0x27 -> path 7 pair 4 RIGHT
0x28 -> path 8 pair 5 LEFT
0x29 -> path 9 pair 5 RIGHT
0x2a -> path 10 pair 6 LEFT
0x2b -> path 11 pair 6 RIGHT
