Question on Using DiGi+ DSP optical input with optical out from TV

Hello - I have a newbie question.  I want to use the HiFiBerry Digi+ DSP board mounted on a Raspberry Pi 4 computer to do 2 things:

1)  Operate as a Roon endpoint (Ethernet In and analog out to separate power amp)

2)  Use the DiGi+ DSP optical input to accept the digital audio output from my TV  and then analog out to same power amp as above.

Can I do both of the above using HiFiBerry OS, i.e. switch between the two sources?  Would switching be automatic when source is started up?

Thanks for any input.

  Yes, with the DAC+ DSP this would work. You need to make sure your TV can output plain Stereo PCM as teh DAC+ DSP can't handle Dolby Digital or DTS encoded signals.

  In HiFiBerryOS, you can enable automatic switching to SPDIF if a signal is detected.

  Thanks very much for answering my question. Is there I way for me to do a Raspberry Pi build that WOULD allow me to play a DD or DTS stream from my TV with a HiFiBerry solution? Something like a Digi + I/O board with a DAC + ? Can 2 add on boards be used on a single Raspberry Pi? Apologies for my lack of knowledge - just starting out on this.

  Unfortunately, there is no such solution.
