Evening, all. It's very rare I ask for help on ANY fora, if I'm honest. I can almost always sort out my own issues, especially with browsers. However, this one has stumped me. I've noticed that, on any website where user interaction requires use of a microphone, the Linux build of Firefox only ever offers "source_default_name" for choice of microphone. Well, OK; I can see this being fine for the vast majority of folks who use a laptop; the built-in microphone WILL be the "default" microphone, no questions. My question is this; what do those of us running desktop PCs do about microphone selection, hmm? A desktop PC doesn't HAVE a "built-in, default microphone", does it? By their very nature, any microphone you're going to use with a desktop is going to be an externally plugged-in device. I have three of these; a USB microphone.....a wireless headset, and the twin stereo mikes on a Logitech c920 webcam. Do I get anything resembling a drop-down list to choose what I want to use? Uh-uh. Firefox - apparently! - doesn't "see" any of them. Not individually. All I ever see is "source_default_name"..... Grrrr...!! C'mon, guys! Frankly, this is about as much use as a chocolate teapot. Linux, to the best of my knowledge - unlike Windoze - doesn't make 'global' device settings, which every application then uses. It's always been far more fine-grained than that, allowing individual device use on a per-app basis. But that only works if the 'app' in question allows those choices to be made. Any Chromium-based "clone" - and I use several of these, as I package portable versions for the Puppy Linux community - will give a full drop-down list of every available device it can find. Why can't the Linux builds of Firefox do the same? I shall be interested to see what, if any, replies I get to this question. It's been bugging me for years...! Mike.
