Mute left or right channel doesnt work

[iieeann]

Since the last 3-4 beta, mute left or right channel did not work. Tried at 4 computers. Use other software ok.

Sorry found the problem.

Under [Internal Audio Decoder], must select [2/0:Stereo].

Select [Same as input] or [SPDIF] will cause left right channel mute not functioning.

I can't reproduce it. Would you describe the steps to replicate the problem?
