Good news, it works! I just made one tiny mistake on the PCB - missed an 'air wire' (unrouted signal wire) between R4 and R8, so channel C wasn't making any sound. This was easily fixed with a jumper.

 

Attached photos show various options for orientation of the USB socket:-

 

1. Vertical external: CH376 module plugged into rear of Micro-expander board. USB socket ~2mm above top of Aquarius case.

 

2. Vertical internal: CH376 module wired internally. USB socket on AY board, recessed ~7mm below top of Aquarius case.

 

3. Horizontal internal: CH376 module wired internally. USB socket on AY board, flush with rear of Aquarius case.

 

I just need to tidy up a few loose ends in the firmware and then it will be ready for Beta testing. Who wants one?
