Here's a project I started to add a S/PDIF output to the Sonos ZonePlayer ZP100. The Sonos is a cute digital audio player that can read music off your network and play it back on your sound system. Unfortunately it has only analog line-level and amplified outputs. I am in the middle of adding the S/PDIF port.
Here's the Sonos during disassembly. The build quality is admirable. The bit hanging off the side is the 802.11b/g radio.
This is the main audio board. There's a TI DSP that handles compressed audio formats, equalization, digital volume control, and drives the outputs. The amplifier is a Tripath TC2000 PWM thing. The line-level output (and input) is handled by the CS42416 near the lower left in the photo.
Probe me harder. The CS42416 has the same 3-wire serial port as every other chip.

An externally hosted image should be here but it was not working when we last tested it.

It gives the impression that sound quality is less important than features 😉 I know, I am terribly prejudiced concerning PWM stuff, I keep confusing them with switching power supplies....
Good luck with it.

Upgrading chipset on Sonos
The Sonos uses a variation of the Tripath 50 W TK2050. Would it be possible to upgrade the chip to the 70 w TK2070 version?

actually, being that im an audio dealer, ive sold a few sonos systems in my time. they arent meant for high fidelity, but great for whole-house audio distribution. but that said, they do sound pretty decent.
im really excited to see this thread! i would LOVE to be able to add a digital out on one of these, or simply a line-level fixed out. it sucks only having variable out... let me know what you find.
