Linux noob. Just got a pair of Skull Candy Push Active XT bluetooth earbuds. They pair just fine with my setup but no sound comes through them. I found many different posts on various forums and nothing helped.
Using the inxi command I pulled some info I think might help, if it's needed. (I don't know if any of this is needed to help fix this issue. I've only been using MX for a little over a week and have never really done a lot of under the hood Linux maintenance before, but am more than willing to learn to fix this issue). If there is sny other information needed, I'm willing to edit this with any of that information, if I can find it.
not sure your exact case, but I would highly recommend using pipewire, Bluetooth audio devices were nothing but pain for me with pulse audio and they just worked on pipewire
It looks like you're still using PulseAudio? I'd highly recommend switching to PipeWire+WirePlumber instead, installing it should make your earbuds work automatically.
When I use my bluetooth headphones I have to physically unplug my wired headphones from the front panel and wired speaker's line-out at the back of my PC, then the audio automatically switches to my bluetooth headphones. There might be an easier way around this but it works for me until I can figure out something better. Running alsamixer from the command line (just type [alsamixer] to run it) can help you see all the inputs and outputs that are working/muted/not seen, this might give you a clue as to what the issue is.
Chris Titus Tech has a pretty good video explaining alsamixer (it's a few years old but alsamixer hasn't changed very much, if at all) https://piped.video/watch?v=gs9I1gPGn9A
While looking through Alsa and PulseAudio I couldn't even find the headset being listed as a connected audio device despite bluetooth saying they're connected to my laptop, so I'd say that's about up to par with my experience with trying to get audio working properly on Linux. The video at least has some good information I could possibly use in the future, though, so there's that.
