Volume control disappearing
dmitch77:
On one of my Macs (of 3), the volume control on MC disappears and becomes unresponsive and nonfunctional when playing. When I start up MC the volume control is there, but when I start playing, it disappears and MC plays at full volume. It acts like it can't make a volume adjustment.
I've been running MC on this Mac (specs below) for years. This bug is new for MC 30. MC 29 still works fine on that Mini, volume control is fine.
MC 30.0.18 (the first and only MC 30 I've run)
2014 MacMini, macOS 12.6
Audio out via HDMI
The attached photo shows MC with no volume control. It's playing, with the audio at full volume.

Some more data:
* The volume control appears normally, and works fine, when the output is set to default / internal speaker.
* When in the failing configuration (audio to HDMI), JRemote also sees a "no volume control" situation; its volume control is hard to the left (off), though the audio is running full blast to the HDMI port.
* The renderer at the other end of the HDMI connection is a Marantz AV receiver.
* Updating to 30.0.20 did not help.

System volume or internal volume control set?
MC's audio device set to Core Audio or to HDMI?
Exclusive mode in MC's audio settings on or off?
Just guessing, I'd assume there is another app fighting for the volume control.

Yep, that was the problem: MC30 was running with system volume, MC29 was internal volume. Somehow MC30 did not pick up that setting during the upgrade. I don't know how those settings/preferences work - how are they migrated? Note that until I just changed it, MC29 is set to Internal volume and MC30 was set to System. So they must be stored separately.

Both actually. :-) The setting says "HDMI [Core Audio]".

On. And MC30 was getting access to the device fine.
Thanks.

Interesting. I assume you restored settings when restoring the MC29 backup into MC30.
I would have thought MC30 would have picked up that value.
