[04:05] <zett> Wireless headphones are not showing up in Bluetooth Device Wizard. Any suggesstions?
[04:12] <arraybolt3> zett: You can try turning the Bluetooth driver off and back on with modprobe.
[04:13] <arraybolt3> I'm trying to find the driver name to give you the directions...
[04:15] <zett> thanks
[04:15] <arraybolt3> zett: Found it.
[04:15] <arraybolt3> sudo modprobe -r btusb
[04:15] <arraybolt3> sudo modprobe btusb
[04:15] <arraybolt3> Try running those in a terminal. That might fix the problem.
[04:17] <zett> it's still not showing up
[04:17] <zett> i'm currently trying to manually connect to the foo bar
[04:17] <zett> but it is saying Failed to connect: org.bluez.Error.Failed
[04:17] <arraybolt3> Do you happen to be fighting with AirPods Pro? You have to do something weird to get those to pair to non-macOS systems.
[04:17] <zett> Nah I'm using JBL headphones
[04:18] <arraybolt3> zett: Do any Bluetooth devices work?
[04:18] <zett> Not sure. I don't have any other bluetooth devices around me
[04:19] <arraybolt3> Did the headphones used to work and then an update made them stop working?
[04:19] <arraybolt3> What OS are you on?
[04:19] <zett> Yeah the headphones used to work just fine but then it stopped
[04:20] <zett> I think I updated Lubuntu probably
[04:20] <arraybolt3> OK. That might be a kernel issue. Can you do "ls /boot" and make a note of exactly which kernels are in there?
[04:20] <arraybolt3> (The kernels are the ones that start with "vmlinuz" in their name.)
[04:21] <zett> config-5.13.0-39-generic  initrd.img                    memtest86+.bin                System.map-5.13.0-40-generic  vmlinuz.old
[04:21] <zett> config-5.13.0-40-generic  initrd.img-5.13.0-39-generic  memtest86+.elf                vmlinuz
[04:21] <zett> efi                       initrd.img-5.13.0-40-generic  memtest86+_multiboot.bin      vmlinuz-5.13.0-39-generic
[04:21] <zett> grub                      initrd.img.old                System.map-5.13.0-39-generic  vmlinuz-5.13.0-40-generic
[04:22] <zett> ^this is exactly what shows up
[04:23] <arraybolt3> OK. The first thing I'd do is boot into the earlier kernel. Reboot your system. When the initial boot screen is finished and the screen goes solid black, immediately hit "Esc". This should get you into a hidden boot menu. Select "Advanced Options for Ubuntu", then select the third item in the list (there should be four items). This should boot you into the earlier kernel. If your headphones work, it's definitely a kernel issue.
[04:24] <arraybolt3> (If "Esc" doesn't work, try "Shift". If neither one works, keep trying until you find the sweet spot - one of them will work eventually. Esc is for EFI systems, Shift for BIOS.)
[04:25] <zett> Ok, I will try this. See you on the other side.
[04:25] <arraybolt3> 👍
[04:29] <zett_> Ok, I've rebooted and did what you said, but there is no difference :/
[04:30] <arraybolt3> Hmm. Are you on Lubuntu 21.10 or earlier?
[04:31] <arraybolt3> If so, try downloading a Lubuntu 22.04 ISO, flash it to a USB drive, and boot from it. Try to connect your headphones in the live environment. If that works, back up your data and upgrade your system to 22.04.
[04:31] <arraybolt3> zett_: Pinging.
[04:33] <zett_> Ok, I will try that, but it may take a while. I think I should probably get some sleep now and attempt to boot tmrw
[04:33] <arraybolt3> zett_: Sounds good!
[04:33] <zett_> Thanks for all your help!
