Hello,
My earbuds would connect to the laptop, but like title said there would be either no sound or sound for literally 1 second then gone, then I can hear sound again when it disconnects but then of course, it disconnects.
I’m dualbooting Windows and yes it works on Windows so it’s not a hardware problem. I have read through a lot of posts and there is one thing left I haven’t try which is using bt-dualboot, because of an error blocking me. But on a fresh install of EOS it does work, but after reboot no.
Can anyone help me with this? I’m new to Linux and Endeavour is the first OS (I know it’s stupid to run headlong into Arch-based at the start, but Linux is the platform for me to challenge myself and try new things with customization), so I don’t know how to diagnose my problems yet but I won’t mind digging in terminal and following instructions.
There are some logs in btmon though:
