PMP audio downmix

Hello. I use PMP with mac mini. When AC3 o any multichannel audio downmixes to stereo the volume is very low and barely it can be heard. How this can be solved?

In ‘fullscreen tv mode’: Settings - Audio - Normalize Downmixed Volume

In ‘windowed mode’: Settings - Web - Player - ‘Show Advanced’ - Multi-Channel Audio Boost

If you are using the ‘fullscreen mode’, there is also another option: an audio compressor.
But it must be enabled with a custom key/button:

Thanks for your help ottokerner. Those settings are enabled. Should I disable them?

Normally not. Otherwise the volume will be even lower.

If you are going to test the third option (the compressor) you better disable ‘Normalize Downmixed Volume’, though.
