An open source universal audio amplifier called ‘U-AMP‘ @ GmanModz, that is available on GitHub:
Using what I learned getting digital audio working on each systems, I set out on a new project I would call “U-AMP” (Universal-Amp). This would be ONE pcb which has the features of seamlessly integrated speakers and headphones with a variety of input sources for digital audio from Wii, PS2, Dreamcast, as well as analog audio input. It does it all. The board is based around the LM49450 IC which I have used many times. The amp is controlled by a PICLF15324; the LF version of the same PIC I use in the WiiPMS.
