Description of Issue
My main listening setup uses an auto-sensing DAC to switch inputs between USB, Coax, and Optical (Accuphase DAC-50). Starting approximately 1-2 weeks ago My Allo DigiOne endpoint seems to be transmitting a signal to the DAC even after stopping playback in Roon. Now when I want to switch to USB playback, I have to unplug the Coax connection coming from the Roon endpoint to free up the DAC to lock onto the USB signal.
This is also happening on a second endpoint (also RPi-4) where the DAC signal indicator light remains lit at the last bitrate that was playing via Roon, even after stopping playback.
This issue is new for me. The only other change I can think of (aside form updating the ROCK and endpoint software on regular basis) is the addition of a Flirc remote control on the Allo DigiOne connected to the Accuphase DAC - controlling that same zone.
Thank you for the response. Something I should have tried before posting, but alas…
I removed the remote extension in Roon and rebooted my core and all endpoints. Issue still persists unfortunately. I have to power down the Allo streamer for my Dac to accept an incoming USB signal. (in case my OP wasn’t 100% clear, in the past I just had to pause playback in Roon to free up DAC to auto-switch to other inputs).
I neglected to mention that both my RPi endpoints are running RopieeXL. I previously used Allo/DietPi but that doesn’t have remote extension support. I could further troubleshoot by uninstalling Ropiee but am not sure what other Rpi OS would support the Flirc remote.
