No sound on mpcstar 5.1, 5.2 & 5.3 when playing MP4

Dear Master,

I’d try to install mpcstar 5.1 / 5.2 & even latest released 5.3 which is the same problem arised that is no sound when playing mp4 video.

By the way, when I installed mpcstar 5.0 & everythings are doing good.

Please advise.

Thank you!

This issue has been seen before, and seems to be related to installing conflicting filters, such as those contained in the K-Lite pack.

It seems to go away if the K-Lite pack is uninstalled, and the CCCP is installed in its stead. You might give this a try.
