Created attachment 131832 [details] LHS: plasmashell with only web browser/webslice | RHS: plasmashell with web radio plasmoid SUMMARY Neither browser widget (nor webslice) will play sound after reboot. I managed to get sound back by kquitapp5 plasmashell kstart5 plasmashell & but everything started acting weird after I did, so, I rebooted and the sound was gone again. I tried removing and adding the widgets back in but still no sound. STEPS TO REPRODUCE 1. Set up browser widget (or webslice) to point to web radio (or youtube) 2. Reboot 3. Browser widget won't send sound through the plasmashell OBSERVED RESULT Browser widget (or webslice) don't show up in sound sources. (Tried a web radio plasmoid which did show up in sound mixer as "plasmashell") EXPECTED RESULT Browser widget to play sound (and show up as sound source in sound mixer) SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 20.04 KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 kERNEL vERSION: 5.4.0-47-lowlatency ADDITIONAL INFORMATION I've tried this with both the stock Web Browser plasmoid as well as webslice ( https://store.kde.org/p/998902/ ) and observer the same results. The web radio plasmoid I used to compare results was Advanced Web Radio ( https://store.kde.org/p/1313987/ )
After updating to Kubuntu 20.10, and KDE Plasma Version: 5.19.5 KDE Frameworks: 5.74.0 Qt: 5.14.2 the problem seems resolved. I've tried a few reboots and the sound seems to work after each.
