Is there any way to mute only one program while listening an audio file in vlc (by ex.) on windows7 ?

Yes. Open up the volume mixer from the main audio control in the system tray.

When you click on it you'll get the master volume but there is an option for mixer. This lets you control each individual application (that is currently outputting audio) level.

Note it will remember these settings so if you mute program A, after you close it A won't be in the mixer (no current output), but next time you run A it will be running as muted.

Yes I posted it and saw you'd beaten me by 17 seconds!! I was very glad to see we were in agreement :o) <either that or I'm trolling for other answers I can quickly copy+paste for reputation> – Dave C Mar 14 '13 at 15:05

Yep, right-click the volume-control icon in the system tray and select "Open Volume Mixer" from the pop-up menu. You can set individual volume settings (including mute) for each program that is open.

Beware that Windows remembers these settings, so it might be polite to unmute the program when you're finished.

To do it from the command-line, you can try nircmd:

nircmd muteappvolume vlc.exe 1
