this issue has been mentioned elsewhere in comments but I can't see that much activity and people are less active on commenting on them. I don't know if Jolla is tracking this issue so opening an issue.

BT audio/music being unusable if wlan is enabled. As soon as wlan is disabled the audio works more or less without issues.

Comments I've seen suggest over-agressive wlan search when no known wlan is in the range.

I have heard the light symptoms since Jolla 1, Jolla C (very occasional stutter) and now with Sailfish X, BT audio is plain unusable. When wlan is on and I leave the house, be in the car etc. where wlan is not available the audio keeps stuttering every 1-5 seconds.

I am not sure WLAN is the problem, I have a similar stuttering experience with using two Nokia 360 speakers (left, right), it usually helps when I disconnect and connect again. Also I have a different issue with car stereo (Navi 600), hands free profile, which disconnects after a couple of minutes.

I can reliably (100%) get rid of the stutter if I turn off wifi in settings. Note that the stutter happens reliably when the phone doesn't see known wlans. It happens a lot less when there's wlan available, although when it's weak (like it is in my office for example) I hear some occasional stutter.

I have tested it with Nokia BH-111 BT dongle, at home using logitech BT recevier and JVC car stereo (Parrot unit of some kind?), where I notice the stutter every time.
