the mix of ifdef is really hard to follow. And on line 148 it's rather suspicious to have SDW1-playback with index 0x202. That looks like a copy paste mistake to me, no?

No, it is intentional. ALH0x202 is the 2nd DAI for SDW1-Playback stream.
From line 54 to 79:

if NOMO (1 rt1308)
Create a normal pipeline 3
else
if NO_AGGREGATION (2 rt1308s but no aggregation)
Create a normal pipeline 3 and normal pipeline 4
else (2 rt1308s and aggregation)
Create a demux pipeline 3 and DAI endpoint 4

From line 139 to 162:

if NO_AGGREGATION (2 rt1308s, but no aggregation)
ALH0x202 DAI is for SDW2-Playback stream
else
if MONO (No ALH0x202 is there is only 1 rt1308)
else (2 rt1308s and aggregation)
ALH0x202 is the 2nd DAI for SDW1-Playback stream and connect pipeline 4 source to the demux

ok, but then let's stop using SDW1-playback, it's confusing. In some cases it does mean playback on Link1 and other it's just the playback stream1...

We can fix this in a follow-up, along with the rename of MONO which is misleading - should be SINGLE_AMP
