Hi, in rel. 2.7.5 audio has stopped to work properly.
On my pc Windows 10 it worked time for a certain aumont of time now it stop.
On GUI is disppeared the bar to control the volume.
If I go to menu and I flag show "volume" it apper but it's grey.
The audio on my pc works fine, I have several audio outputs, I switch between them whitout problems...
Someone can help me?

You must have inadvertently switched "AudioDevice" in the "Audio" tab of Avidemux Preferences to "Dummy". Please switch it back to "Win32".

Unrelated to the topic, I would generally recommend using the latest nightly rather than the increasingly outdated release, especially when dealing with mp4 files.

Avidemux win64 MinGW builds: https://avidemux.org/nightly/win64/

You are right!
Many thanks.
I've tried to install the last release you suggest but smartscreen of windows block installation of unknown app :-(

I can't help with smartscreen issues (and the project cannot provide digitally signed binaries), but you might want to try the zip-packaged version. It doesn't need to be installed, just unpack it to a directory of your choice.

The builds I pointed to are not releases but snapshots of ongoing work on Avidemux.
