S/PDIF kernel module

[mill1000]

The end goal of this project would to be a kernel module for S/PDIF output. Something along the lines bcm2835-i2s but for S/PDIF

That would be very cool if it could just be used like an ALSA device!

Yeah! I've contemplated making it a kernel module that provides a /dev/raspdif endpoint which could be written to. It would be a step in the right direction.

In the meantime, you inspired me to whip up this ALSA configuration for raspdif. You can either use it in your .asoundrc or /etc/asound.conf. With this config any ALSA compatible player should work.

I also added the systemd service I've been using.

I'll update the README when I get a chance.

Closing this as a "won't do" for now.

Found this project today: kiffie/rpi-i2s-spdif. Same ideas as raspdif but the creator knew enough about kernel modules to make it work.

Reopening this issue since the above project would be a good reference
