I understand that there is rooxtend that allows the integration of a USB-type CD player into Roon. That is not an option for me. I have a very nice TEAC PD 301 CD player with optical/coax out as well as the analog single ended out terminals. I feed my Audiophonics RoonReady (via roopiee) streamer via optical input and i would like to have DSP capabilities that are available under Roon.
Is there a way with or without additional hardware to use the CD player as a source that feed into Roon?
No there is not. It’s a file based server client software not a standalone DSP processor . There is another extension that does the same as RooExtend for free called Entrypoints this can run on other computers than a pi and does exactly the same. But you need to have away to feed the digital or analogue signal into it to route it towards Roon. Or buy a minidsp hardware box. Those are your options currently.
