Quoted from chillme:
Looking at the Pinsound XL card, it has two HDMI ports, so it's a bit different than the standard boards.
I have a pinsound in my TZ and it helped pump up the sound since it has adjustments for treble, mids, bass. This XL card doesn't look like those dials are there on the card. Maybe it's done in software?
Dials are on the middle of the card.
