Media Player Classic doesn't play voice audio properly.

I have some music audio files added at their beginning voice audio generated by NirSoft command “speak text” to say the music names. The voice audio and the music audio were edited together to one audio file in flac format by Audacity. When edited songs are played by a player, the names get said first and then the music. All other players have no problem of playing them normally as expected, but MPC always says the incomplete first part of the voice, and then again from the beginning says the full voice and the then music, any clue?
How do I submit an example?

You can upload sample to for example http://www.sendspace.com

the link is not working:502 Bad Gateway

You can also use any other file hosting website. Or Dropbox or Google drive.

ok, try this link, and let me know if you can access it:

I use MHC add a directory and it's subs and then randomize nearly 7000 songs of them to play, all good with the exception of voice added to the front ones.

I can reproduce the problem with this file.

I can't promise a quick fix. I need to contact the codec developers.

already a few years, i always hoped a fix with next update and never reported it, thanks.

We can only fix problems is we know they exist. So always report problems.

I can submit/upload more samples if needed, but they should be the same cause, and i can help test new updates on my collection before release, it's a small bug, programmers will have fun to catch it. enjoy and regards!
