I discovered a problem with X today, and I'm not sure what's causing it or when it actually started.
I was looking through my X timeline, and wanted to hear what some of the people were saying, but there was no sound. According to the speaker icon in my system panel, sound is on. And the audio settings agree with that. I've checked everything that has anything to do with Vivaldi, and it all looks good.
To see whether other applications are affected by this, I launched Elise and selected a music track, which played normally. I also used Vivaldi to stream my TV output to my laptop, and that worked fine.
Has anyone else noticed this? Anyone have an idea what I might do to get sound from X?
