Bluetooth repeatedly switching on and off, no audio, broken behavior

tv flag

I have some really odd behavior with bluetooth. There are a few seemingly related issues that are all resolved by rebooting Ubuntu- haven't found any other solution, and I've tried a fresh OS install.

  • repeatedly and rapidly connecting/disconnecting my wireless mouse while mouse is unresponsive
  • audio devices refuse to connect (e.g. connect then instantly disconnect)
  • Device connected and audio is visualized in device settings, but no audio played
  • Really odd mouse scroll wheel behavior: say I'm scrolling down as usual. Scrolling up once has no effect, and I have to click it up one more to make it scroll up once. Also happens in the reverse direction, so it's almost like a null zone or looseness, if that makes sense. Seems to be caused by the mouse going into sleep mode?

Hardware: Laptop: Asus Zenbook UX3402ZA (dual-booted w/Windows 11) Devices: Katar Pro Wireless (when on bluetooth mode - USB dongle mode is non-problematic), JLab Studio headset, generic custom printed "lantern speaker"

Software: Ubuntu 22.04 LTS on SSD, 22.10 installed on SD card (kernel 5.19.0-38-generic)

I believe the problems don't happen on a live USB boot of the two OSs, and I've never had the problem my Windows 11 side, but I'm having a really hard time finding a pattern of cause and solution (other than, the issues sometimes happen at boot, and are usually resolved by rebooting - possibly related to the laptop and/or mouse going to sleep).

Output of systemctl status bluetooth (while issue is not present; will try again when issue shows up again)

Update 0:

  • No signs of the speaker/audio problems anymore, possibly resolved by the fresh install or maybe the lack of pulseeffects (I happen to not have reinstalled my EQ stuff yet).
  • The scroll behavior problems seem to not happen on live images but can be triggered on full install OSs by complete inactivity for a few minutes (the laptop screen doesn't have to time out for this to happen).
  • The connect/disconnect loop seems to happen only on a full install but can happen immediately after booting up. Comes/goes at random.

Please no pictures of text. Cut and paste into the body of the question. Makes it easier to read, prevents info cut off and makes it possible to search.

@David ah sorry, forgot about that - should be fixed now. Let me know if anything else is missing.

Do these problem also reoccur when running a live Ubuntu session from the bootable USB that you used to install Ubuntu?

@karel Although so far I can't pinpoint a way to intentionally trigger them, they seem to not be happening on the live boot - will update if they do begin to show up.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
