Comment 3 for bug 1738404

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
