Due to a health issue I have very reduced hearing in my left ear. Because of this I often listen to music in mono instead of stereo. The macOS audio controls (under the accessibility settings) allow me to select that the stereo output be converted into mono, however this doesn’t seem to work with the the DAC I am using the Schiit Fulla 2, which stubbornly continues to output in stereo. It works fine for the built in audio output.
Is there a way to get a mono signal to my external DAC instead of stereo? I mostly need this for iTunes but would prefer it be system wide
Thanks in advance
EDIT: I know This can be done with apps like Audio Hijack, but I was hoping to do this at the system level and not have to have an app running when I want to switch output to mono.
Also I tried my DAC in iOS and it work with the accessibility settings to switch the output to Mono so it looks like a limitation of macOS at this point.
