Since upgrading to 2.657 I have no ability to control volume. Posted the following on another thread on 10/22/19 (#p68205), below. michelangelo, you replied same day saying you were able to reproduce and would have a fix soon. Have you had any luck? Seems several others are having the same issue.
Today I upgraded to 2.668 and have same issue, same output in volumio.log and aplay -l. I can hear sound when playing web radio, but no audible sound from Spotify. Volume is fixed/non-adjustable for web radio. If I choose “Software” or “None” for the mixer I get no sound at all. When defaulting to “Undefined” I can at least get fixed sound for web radio, as mentioned.
Sorry to be so verbose. Just hoping some of this may help bring a solution.

"I also have the same problem after update to 2.657. I have Rpi3 with USB AudioQuest Dragonfly. Really don’t want to do a factory reset. Doesn’t help to use software defined mixer either. Volume is fixed and not adjustable. Any ideas?
volumio.log shows the following when attempting to adjust volume:
