Hello Keef,
Try this mute utility (from a trusted source)
http://edmullen.net/utility/mute.exe or access Ed's utility page
here. The utility was featured in a PC magazine article some time ago. It's a toggle - each run inverts the mute status. Place the mute.exe program in your Windows/System32 folder.
Now you can open control panel and run Task Scheduler from there to add the task location and time or if typing cryptic command lines are your idea of fun around the computer, try the following in the Start > Run dialog:
schtasks /create /tn mute /tr mute.exe /sc DAILY /st 22:00:00 /ru System
Switches:
/tn Task name - arbitrary
/tr Task program name - if located in your system32 directory, no path needed otherwise type the full path to the location of your program to run
/sc Schedule type - in our case, daily
/st Start time
/ru - Runs as user - the word
system runs command as current user
You can see all of the switches and options by typing schtasks /? or searching Windows help for schtasks.
This will create a recurring task every day when the computer is running at 10pm to mute the speakers. By changing the task name and start time, you can un-mute the speakers in the morning the same way. To view scheduled tasks, open a command line (type CMD in the Run window) and type schtasks.
Chances are fair to good that the USB headphones can similarly be controlled via a built-in app that can be run with a command line switch.
Best of Luck!
If you create a shortcut to mute.exe on your desktop or quick launch bar, you have 1 click access to the mute function of the PC sound card.
***Please note: Since mute.exe is a toggle, speakers will be ON if they were OFF when the task runs.
