This is important to point out. I donated double because the guy (Tolriq) updates it like every week and is always adding new features.

He just added native sonos support for grouping, individual volume control etc…

By far Symfonium is the best. There is no competition.

He even helped me figure out how to find my product key when it wasnt appearing.

Currently operating on GrapheneOS w no google for a few months now with no issues at all.
