When playing mulaw wave files on Firefox, I get a lot of static, much more than I do on Chrome. You can test this here: https://www.tavoca.com/audiotest/index.html You can download the original wave file here: https://www.tavoca.com/audiotest/mulaw.wav I tried using Firefox 78 and 76 on Windows 10 and on Linux Mint 19.3 I use the default theme, no extensions, only the basic plugins: OpenH264 from Cisco and Widevine Content Decryption Module from Google. Is this a known issue? Is there already a ticket for it, and if not, how can I create one? Thanks, Laurian
