A few ideas come to mind: - Cambridge Silicon Radio dongles are historically unreliable. I found my Bluetooth devices were excessively buggy with them. And other people found the same. Try a different brand if you can.
- Can you please check what audio profile you're using in sound settings for Bluetooth? Make sure it is A2DP for the best quality. Not HSP/HFP. Is the problem just the wrong profile defaulting? - Bug 405294 - Kernel regressions... Please try an older kernel more in line with what 17.04 had (kernel version 4.10 or older): http://kernel.ubuntu.com /~kernel-ppa/mainline/?C=N;O=D Probably less relevant: - A regression in bluetooth in 17.10; sounds like it is Intel specific though: bug 1729389 ** Changed in: bluez (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1738404 Title: Bluetooth sound extreme low quality To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1738404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
