I planned to purchase a RPi4 and the DAC+ DSP board to take a digital (coax) signal from my laptop, perform some EQ on this, then output it on the same board via digital (coax) out.
I just wanted to confirm:
- Is this currently supported on HiFiBerry without too much drama?
- Is the same thing possible running a 'mainstream' distro (i.e. Ubuntu)?
- Is the DAC+ DSP the correct board? (I'm aware a Digi+ IO board also exists)?
- Can this be controlled via the web interface?
