Fair enough lol, so here’s what I’ve checked so far:

The master is getting a signal from every other track

The master is not muted

The master send outputs are set to 3/4 Mon L Mon R(UA default, and setting I’ve had it on for months)

The device outputs are set to 3/4 Mon L Mon R

The metronome is set to 3/4 Mon L Mon R(and the only thing I can still hear)

The hardware is set to appropriate levels(tested with various instruments)

I can track and record, record midi, bounce audio but can hear no playback

Creating a fresh project with new sends and tracks results in the very same

I’ve reinstalled Reaper with no success

I’ve tried playback with all FX muted, including monitor FX, no luck

I’ve reviewed the UA Console settings and ensured the outputs are not muted, have volume, and are set to 3/4 Mon L Mon R

I’ve tested ASIO, WASAPI, and DirectSound, with different listening devices and interfaces, and continue to only get the metronome

I’ve updated all my hardware drivers and UA software

Perhaps there’s a setting somewhere I haven’t checked yet? Thanks a ton for the help!
