I've lost sound on two streams that I know continue to broadcast. To avoid leaving lots of red herrings lying around, here's why this is a mystery to me: My speakers are working fine. I get sound on YouTube and other streams. I've had a sighted friend check one of the streams because the volume control is inaccessible with JAWS. She confirms that the sound is set to "loud" and the video is playing on the screen. The other soundless stream played briefly when I switched from IE11 and Firefox to Google Chrome. However, when I shut down that window and later returned to this stream, I got a message saying my browser wasn't compatible, and that's been the case ever since.
I lost the sound on the first stream after I made a mistake with my speakers' remote control. It should have done nothing to affect the sound, and all my other sound streams and applications weren't affected. However, it did seem coincidental that I lost the sound at that moment and couldn't restore it. I have Windows 7, JAWS 18, and the three browsers I listed. Does anyone have any suggestions?
