Success! I was able to pair with my Soundouch speaker, again. I left the speaker unplugged overnight. I turned my phone off and restarted it. I had to readd the speaker, but. it paired.

Try to re-pair it after 2 weeks later. Power already turn off for 2 weeks. Resetting default setting on the sound touch 300. Same problem, bass module able to pair immediately on the first attempt, not for the VI surround speaker.
