Zoom Inc. Zoom Video Conferencing - Why is sharing computer sound not working for me?

Question

I am testing the free version of Zoom at home using my primary Windows 10 desktop PC, which has a wired Ethernet connection, plus an iPad and a Windows 7 laptop, both of which are connected to my home network via Wi-Fi. All of these are signed in to Zoom using different accounts.

The microphone connections are all working fine and I have no problem sharing my desktop and sharing video sources. As the host, I selected the 'Share computer sound' checkbox in the Share Screen window (plus the 'Optimize Screen Sharing for Video Clip' option), but the video sound track cannot be heard by the other participants. They also can't hear any music I play. Where might I be going wrong?

Accepted Answer

Yet more testing has shown that after Foobar200 and VLC have been blocked by trying to share JRiver Media Center playback over Zoom, this problem can be fixed by restarting Zoom on the host computer. It is not necessary to reboot that PC.

Answer

After further investigation, I have now found that my problem only occurs when using JRiver Media Center to play audio or video files on my primary PC (the Zoom host). Audio files played using Foobar2000 work fine over Zoom. So also does the sound track of a video played using VideoLAN VLC Media Player.

Something that is particularly puzzling is that once I have tried and failed to share anything over Zoom using JRiver Media Center, then both Foobar2000 and VLC stop working. Closing JRMC and checking in Task Manager that nothing related to JRMC was still running made no difference. Foobar200 and VLC only started working again over Zoom after I rebooted my PC.

Answer

I got a solution to my original problem via the JRiver forum. Turning off the exclusive access option in JRiver Media Center's audio settings enabled it to work properly with Zoom.
