I recently purchased a Hifiberry DAC+ ADC Pro board (attached to pi4 running HA) which I can successfully use as Output device in Spotify Connect after following these steps: Is there anyone running a HifiBerry DAC on a Raspberry Pi HA setup?
However I’d also love to play my Turntables analog output through the same speakers (what the ADC if for). So I basically need any player or passthrough that allows the analog audio input of the soundcard to be played vis the analog output of the same soundcard.
I read that alsamixer is generally capable of doing so, but did not find any startingpoint yet in HA yet.
Does anyone have an idea?
