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 Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1738404 Title: Bluetooth sound extreme low quality Status in bluez package in Ubuntu: Incomplete Bug description: I upgraded today from ubuntu 17.04 to ubuntu 17.10. I use 3 different bluetooth audio devices ( BT earphones, BT speaker, BT BOSE Soundlink speaker) , all of them worked properly on 17.04. Since the upgrade, the sound gets continuous interruptions/cracking. These sound interruptions and cracking are so annoying that I cannot keep on listening to music. I could relate this to the fact that a new BT stack has replaced the former in Ubuntu. If I use wired devices (hdmi connected screen+audio, the sound quality is good and as before) so the issue is related to the use of the new Bluetooth stack. I have not found a way to parameterise it neither. I have not found any similar report. "apport" seems not ot exist in thise version, I cannot find and execute it.
