[LAU] Help finding a forum for PipeWire?

Hello, all, I tried to replace my audio stack on my everyday, all-purpose Linux Ubuntu 18.04 desktop with PipeWire. Overall, it went smoothly, with one exception. So far, I've mainly used it to listen to audio from Firefox, from YouTube videos, etc. Every time I perform an action on the YouTube video (start or stop the video, move the timeline back and forth, change the playback speed, etc.), the Sound control panel either shows a new Firefox source, under the Applications tab, with the volume set to zero, or the existing Firefox source is slid to zero. Before I can hear anything, I have to bring up the Sound control panel and slide the control up. I know this isn't a PipeWire support forum, but I haven't been able to find one for PipeWire under Linux or Ubuntu. Does anyone know of a support or user's forum where I could ask this question? Where would you go to ask this question? Thanks for your help and advice. -Kevin
