Can Sonos put an update so you can adjust the volume level of Arc just in the same way you can independently adjust the volume levels of the Sub and Sonos Ones (surrounds),  when all four are linked in a home theatre set up. Since the new firmware update the Arc sounds more suppressed /muted.

Also, it would be very useful if in a future firmware update if Sonos can add to the existing EQ treble and bass, an additional mid-range level adjustment. i.e. User adjustable treble, bass and mid-range too! This would really help those who want to tweak vocals and mid-range in music and movies like they do with bass and treble. It would be particularly useful for soundbars like the Arc, but also would be nice for other standalone speakers too. The dialogue enhancer feature is too restrictive and does not work with pure music playback (non movie) and is not a substitute for mid-range EQ level adjustment.
