When watching a video on YouTube, the sound suddenly stopped playing. Currently, sounds in video and audio are not played on all sites. The problem is only in the browser. Audio and video files are perfectly reproduced by the VLC player. There is also sound in the Chrome and Firefox ESR browser. My actions. 1. Disabled all extensions 2. Clearing history and deleting all cookies My browser - Firefox Developer edition, version 123.0b9 OS - Debian 12 P.S. I have been using the developer edition for many years. It seems to me more convenient and faster compared to regular Firefox. I really don’t want to delete the customized browser. I need help with audio in browser... Many thanks!
