AC3 file keeps playing in Avisynth

[smike]

I'll explain. I have an MKV file, and I could only get the audio to play by converting to an AC3 format. However, with the trim function used, it will play the entire audio file even with the trim.

This happens on Media Player Classic, but not on the Black edition. Is there an adjustment I can make so it plays normally in MPC?

You shouldn't need to convert to AC3

Post your script

Are you aware that some media players will play an audio with the same base name as the video? Ie, if your AVS script is named FILENAME.AVS, and there is an audio file named FILENAME.AC3 in the same folder, the media player will play the AVS script and the audio file. There is usually an option to enable/disable this behavior.
