Hi Guys,
I'm interested in reading track/title information from a S/PDIF optical or coaxial digital audio receiver
chip Cirrus CS8416.
Is there any examples of retrieving this information from the receiver chip?

I want to allow the DAC to decode the serial audio, so don't need to touch that.

Cheers, Art.

It appears it's just an I2C interface waiting to be talked to.
I'm surprised nobody's done it yet,
as it seems some cool information is available such as
digital level and track (time) info (at least).

First up I want a pair of linear LED level meters from levels captured digitally.

The chip also makes some status available such as lock/error conditions
that can be counted by a micro.
This laser demo will look cooler when the receiver can display lock and error status:

... Was a bit of a sidetrack :)
It's the chip in the receiver end that is ready to spill it's guts.
