So for some reason my HEVC MKV conversion profile is causing the converted WTV file to lose it’s AC3 Audio Track and only have Stereo. I’ve double checked that Mult-Channel Audio is selected in the settings (along with choose the best audio track), so I am not sure what would be causing this. Could someone look over a Log File and see what I probably have setup wrong?

Just to follow up…I updated the HEVC MKV profile to copy audio instead of whatever it was doing before and I still got the same result with only stereo in the converted Audio file.

```
   [HEVC MKV]
Description=HEVC in MKV (H.265/AC3) conversion. Creates a smaller file (50% smaller than H.264) with comparable quality but very slow.
order=handbrake,ffmpeg

handbrake-audioac3=-E ffac3 -R auto -B 256 -D 0 -a 1,2,3,4,5
handbrake-ext=.mkv
handbrake-audiodelay=skip
PreConversionCommercialRemover=true

```

I didn’t touch anything in the Handbrake section of the profile so I am guessing that something is happening during the conversion to H.265 that is changing the audio track.

Any thoughts on this?
