I often join BlueJeans conferences initiated by a major client. When I am at my office PC, I have to use the program via a browser on my physical desktop rather than through my office environment's virtual desktop (which disables audio). I usually plugged earphones into the PC CPU box, and it worked fine. However, I recently installed a second video screen on my PC. Now I can no longer hear the audio in this way and need to also dial in by phone and mute the PC speaker to do a video conference. Is this because of a resource drain on the PC, or is there some setting that the new video screen somehow interfered with? Is it that I am using an outdated plug-in? Any advice would be welcome, although I can live with the work-around if necessary. Thank you for your help.
