Tried playing some older files but the audio comes out of left speaker only when using mpc hc. using WMP it plays correctly. updated to latest codec hasn't fixed the issue.
tried enable/disable audio switcher, enable custom channel mapping didn't help. same issue on multiple computers. any help would be appreciated.

Can you upload a file that has this problem? Or send me a (torrent) link where I can download one.

It correctly plays stereo here.

What is shown here?
MPC-HC menu > Play > Filters

It should be using LAV Audio Decoder.

Checked again and the right channel is indeed empty.

I don't have a solution for you right now. It seems to be an issue with the FFmpeg decoder. I can't predict when that will be fixed.
