I presently have a Beresford DAC strapped to the back of the TV with its
two optical inputs driven by 

1.A Chromecast Audio dongle receiving via Castbridge

2. A TV which has a Chromecast Video Dongle attached - this dongle is
also recognised by Castbridge and audio may be streamed by that route.

LMS sits on a old PC and works well enough though a Raspberry Pi would
use less power!

The old Beresford DAC is able to drive the amplifier and speakers (when
switched on) and, with  a separate volume control, drive headphones, so
I have a setup that suits my needs well.

I have seen the HIFIBERRY DIGI+ I/O advertised

https://www.hifiberry.com/shop/boards/hifiberry-digi-io/

and I wonder if a Raspberry Pi  with this hat and PiCorePlayer would
allow me to achieve the same ends as above.

Is it possible to use the I/O board for TV sound loopthrough? Would
PiCorePlayer control the hat effectively for that purpose? I note the
latest PiCorePlayer has graphical control of ALSA mixer, and that gives
me hope. Deep modification of the underlying Linux would be beyond me.

If this were possible a passive splitter on the analogue output of the
HiFiBerry DAC would allow me to drive both the Loudspeaker Amp and a new
Headphone amp with independent control.

Is this a sensible approach as I look to replace ageing hardware? What
other options might I have? 

A new external DAC with

would be one.


It must be a common need to merge TV sound into a quality lounge audio
system.
