Hello,

I am having an issue with my Bluetooth headphones (Sennheiser HD 450BT) in Firefox on Windows 11.

The headphones are properly connected to Windows and work correctly with other browsers (Edge, Chrome).

Windows shows the headphones as the default output device (stereo), and test sounds play through them.

However, in Firefox, the audio does not go through the headphones. Instead, it plays very loudly through the laptop speakers.

The problem started today; there were no issues for about a year.

I have tried reconnecting/reinstalling the headphones, but it did not help. Drivers are also up to date.

Could you please advise how to make Firefox correctly use my Bluetooth headphones as the audio output device?

Thank you for your assistance.

Tell me why I have no sound on Firefox and how to fix it. I do have sound on DuckDuckGo and AVG Secure Browser. I have checked my sound setting 55% and not muted. I have shut down and started laptop, still no sound. I checked Firefox updates and am good.

Today my Facebook has no sound. My laptop has sound. Youtube has sound, NBC has sound, Amazon Music has sound, NPR has sound, it's just Facebook that is WITHOUT SOUND. So that is why I am wondering, does Firefox/Mozilla have sound settings that I might access to fix something like this?

I have already tried rebooting the laptop. Rebooting the browser. Rebooting Facebook. Thank you in advance for whatever help you might offer, Pamela

Hello All,

I noticed that while YouTube videos play with no problems (despite those videos not starting automatically if I open them in a new tab) YouTube Music does not play anything at all. If I open it on my Android Smartphone it works like a charm, but on desktop Firefox nothing.

I'm using Linux Mint 22.3 - Cinnamon 64-bit Kernel 6.17.0-19-generic Desktop Environment: Cinnamon 6.6.7

I installed the ffmpeg codec package Cleared cookies and data for YouTube I did some research on my own and enabled in about:config "media.ffmpeg.vaapi.enabled set to False" Enabled in settings Play DRM protected content Disabled using Hardware acceleration Also PulseAudio is installed

Thank you in advance to anyone who can help me understand what's happening

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...

I cannot get audio to play on the browser. I've gone into settings and the default says that audio should be on for all websites. However, Youtube, facebook, instagram, etc., won't play audio. Audio plays on other browsers (Chrome, Edge). what must I do to get audio working?
