I experienced a similar Bluetooth audio connection problem with Nothing Ear (2024) on Linux Mint 22.3.
**System details** - BlueZ: 5.72-0ubuntu5.7 - PipeWire: 1.0.5 - Bluetooth adapter: Intel AX201 **What happened** - Initially, the earbuds could be discovered and paired, but they did not appear as a PipeWire audio output. - After a reboot, the device disappeared from the paired-device list and was unavailable to `bluetoothctl`. - The earbuds were discoverable during scanning. - Re-pairing the earbuds, marking them trusted and connecting manually restored audio. - During earlier failed connection attempts, the Bluetooth system log showed: `profiles/audio/avdtp.c:avdtp_connect_cb(): Function not implemented (38)` The Hands-Free Voice gateway also reported `Function not implemented (38)`. **Current status** After re-pairing and trusting the earbuds, I restarted the laptop again with the earbuds in their closed case. The pairing persisted, and the earbuds connected automatically when I opened the case. Audio playback now works normally. I cannot currently reproduce the issue. I am sharing these findings because the AVDTP error appears similar to the connection failure described in this report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2159829 Title: Regression in BlueZ 5.72-0ubuntu5.5 prevents A2DP connection to Amazon Echo Dot 4 on Ubuntu 24.04.4 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/2159829/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
