Added support for passthrough audio on rpi in alsa-lib #20

Closed fredrik-eriksson closed 4 years ago

alsa-lib on gentoo is missing configuration for the iec958 device on bcm2835. This PR adds a patched version of alsa-lib that adds the required files.

I got this method from here, here, and some trial and error; there may be better ways, but this Works For Me...

Thanks! I'll take a look over the next few days.

OK thanks. Looks good. I'll pull this then tweak it slightly, to make your changes conditional on a new USE flag for the package. This will then allow me to mandate it in the metapackage (preventing main-tree bumps overriding it).

You need to use the bcm2835 USE flag to turn this on.
