This may to be a Tumbleweed problem, because I have 3 distros on the same laptop, and the audio DOES work in Vivaldi on the other two (Mint and Kaos). Further, I have Vivaldi installed as a flatpak with --user, and so the SAME vivaldi is shared among all three distros.
Audio in Vivaldi WAS working in TW until sometime within the past week.
I’m running TW (and Kaos) with KDE plasma. Mint is using the Cinnamon desktop.
On TW, audio DOES work from the system settings, in VLC, and in the Brave, and Chrome browsers (which I installed for testing). Just no audio in Vivaldi (which is based on Chromium and so related to the other two browsers). Of course, this evidence suggests this might NOT be a TW problem, but a Vivaldi problem!
Any advice appreciated.
