Source Monitor Audio
The "sum multichannel outputs to mono in source monitor" is not working / not summing all channels.

The clip is 4 channel adaptive to 1 audio clip.
If I slide channel one down, I can hear audio from channel 2; if I also slide channel two down, no audio can be heard though there are levels showing on channel 3 and 4.

I'm not able to replicate this. Can you let me know which version of the application you are using?
