Same for me. Tried all of these as well... So the hamsters started to run a bit faster and it occurred to me to reset the speaker.
Step 1: remove paired Bluetooth Speaker ("Bose Mini SounLink" in my case) from "Bluetooth Preferences"
Step 2: reset speaker
To perform a SoundLink® speaker reset, following these steps:
- On the speaker, press and hold Mute for 10 seconds, the LEDs will flash briefly
- Press Power to turn the SoundLink® speaker back on

Step 3: Turn on speaker and pair normally.
Working flawlessly now for about an hour....... fingers crossed.
