Hi @jhnmarsden,
I’m unsure about your issues, and what may have changed to cause it. I know that 0.7.5 has introduced a few changes to the Audio/Video conferencing features but I was under the impression that it was stable and improved things rather than causing the issues you mentioned.
The most likely candidate in your case is a long standing bug in Foundry which can cause audio/video not to be sent even after the connection is established between two players. Self hosting has the same issue, and actually, wouldn’t solve anything since audio/video is entirely peer to peer and doesn’t involve the Forge servers (unless in rare cases where peer to peer connectivity is impossible to achieve, but since you say reloading fixes it, it’s not an issue of being unable to connect to each other).
AA lot of those who have had similar experiences have switched to using Jitsi for their audio/video, as it isn’t plagued by the same bug and it also has the advantages of using less bandwidth and CPU, making the visible quality of the videos better. It’s easy to use, as you simply need to enable the jitsirtc module, no configuration would be required.
If you’re interested in the more technical details, I’ve written up about it before in this post :
I hope that helps.
