I can’t get it to work with the .99 release.
The Mixer Control dropdown is empty.
After upgrading to .992, my only choice for Mixer Control is “Soft Master.” But that doesn’t give me the ability to control volume from the UI.
(On the other hand, it looks like my NAS mounts reliably on reboot …)
p.s.: Volumio 2 is getting better and better. I like the new choices under Music Library. I guess I can only whine now about an advanced search that lets me select multiple genres, which also suppressing other genres … all coupled with supporting multiple genre tags. Great going, team!
