I do not want any sound at any time: I want all sounds either muted or vibrate.
I have multiple routines, some are stock routines and others are those I have made. All of my routines either set the sound to mute or vibrate. Regardless, each day, the sound is turned back on by Bixby routines. I know this because the sound wakes me up. Annoying and irritating.
I've checked all my routines already. I've even go so far as to create two routines:
To me, this is a clear bug.
Model: SM-G975U (s10 Plus)
Android ver: 10
Bixby Routines ver: 2.4.32
Have you tried to force stop and clear cache on all Bixby related apps? Try that and see if that helps any.
Navigate to your settings > apps > Find and click on each individual apps Bixby Home, Bixby Vision, Bixby Routines, Bixby Service, Bixby Voice > force stop > storage > clear cache.
It did not work.
Yesterday, I did what you suggested: force close and then clear cache for each of the Bixby processes running.
This morning, I woke up, opened my phone and checked my volume: muted, as expected. Then, a proximity routine "Home" ran: this is triggered by location, sets the sound to "vibrate", and it started to run. The sound was turned on again!
