Bluetooth audio went from good to stuttering - solved
The bluetooth audio worked almost perfectly on my Sailfish X, but after a month or so it started stuttering so badly it was basically unusable.
After reading about flushing the bluetooth cahche, I went to bluetooth settings and removed the last device I had connected from the list (a cheap bluetooth gamecontroller).
I connected my bluetooth headset (which still needs to connect/manual dissconnet/reconnect before properly connecting), and -BAM- silky smooth stream again!
Hope this info can help someone frustraded with bluetooth skipping.
