I am apparently not the only one who likes to play some type of game online while listening to music clips or video. Until now, I had to wait for commercial breaks or hit pause in order to satisfy my itchy gamer fingers.
Finally I started searching online for a way to turn off the sounds on games. Eventually I was able to identify what I wanted as a mute on Flash games.
And THEN I finally lucked out on the right forum that gave a link to a CNET download for FlashMute, a free piece of software that does exactly what the name says, puts a mute on your Flash game noises. The program is a mere 1.66 KB big.
See the CNET review and download page here.
So now you know where to get it, and for free.
AMENDED TO ADD:
After only a couple days, the FlashMute no longer worked. I think that a registry n cleaner app may have "fixed" the Flash program that I did not want fixed. So then I did another search.
I found this page online. The writer notes that he stumbled onto a way to silence the Firefox browser by clicking on the Sound icon in the lower right corner of the computer screen, and bringing up Mixer. (I right-clicked and then clicked on Open Volume Mixer.) Then you can select Mute on Mozilla Firefox. You can also opt to adjust volume of windows sounds and of devices.
This "final solution" is working like a charm.
