@leo oh, wait! do you mean having the normal pedal output be suppressed for the headphone output, and instead it only outputs what is received via usb? i think that'd be called disabling monitoring rather than disabling loopback. i would have to check the manual…

@hikari yeah, i was calling it loopback bc of the pulseaudio module name lol

@leo i checked and there's an option in the pedal's settings to adjust the monitoring balance, by default it's 50:50 incoming usb audio vs pedal output, but you could set it to 100:0 for the use case you envision

@leo “loopback” is fun because it's both a thing you might want a computer to do (mix microphone/guitar audio with outgoing computer audio and send it back to the audio interface for listening) and a thing you might want an audio interface to do (mix microphone/guitar audio with incoming computer audio and send it back to the computer for recording), and indeed both kinds of loopback exist!
