MPC-HC no sound for some videos through speakers

[HVD]

Hi there,

I'm having a problem with MPC-HC, and it seems to have started suddenly. Everything was fine earlier today, and I'm 99% certain I haven't changed any settings since then.

Basically, when I play most movies, whether mkv, mp4, or avi, there's no sound being played. However, if I check the Windows mixer, I can see the little green indicator for both MPC-HC and the speakers moving, which shows that sound is being output somewhere. If I plug in my headphones to the front panel, the sound works perfectly, only to disappear once I unplug them again.

This doesn't happen with all movies, certain mkvs work fine through my speakers, it's just the majority which don't for some reason.

Any help you can give would be appreciated.

EDIT: it seems that the majority of mkvs work fine, it's just one or two that don't

What did you do differently to make the MKVs that don't work?

I didn't make them so I can't really say. I did a quick survey of a few videos and listed their audio tracks along with whether or not they worked:

Video 1 - MKV - 5.1 ac3 - working
Video 2 - MKV - 5.1 ac3 - working
Video 3 - MKV - 5.1 dts - working
Video 4 - MKV - 5.1 dts - working

Video 5 - MKV - Stereo ac3 - broken
Video 6 - MP4 - Stereo aac - broken
Video 7 - AVI - Stereo mp3 - broken
Video 8 - AVI - Stereo ac3 - broken

Video 9 - AVI - 5.1 ac3 - working

So it looks as if the common factor to the broken videos is that they have stereo audio, but I have no idea what that implies or how to fix it

EDIT: if it helps I originally setup MPC-HC according to this guide: http://www.avsforum.com/t/1357375/advanced-mpc-hc-setup-guide minus the dtsdecoderdll.dll and Reclock. I don't recall changing anything today that would break stereo audio though

I didn't make them so I can't really say. I suppose you didn't read our forum rules either. Closed for rule 6 violation.
