Thank you, Rick,

The 'disagrees about version of symbol...'s are dmesg is probably not
a problem, as long as we don't need the midi stuff. The cause is my
package lacking the midi modules.

Headphone is muted. If you unplug and plug again, is it still only the
Speakers control (and second Headphone D) changing? Can you unmute
Headphone manually (with M)?

I suspect that the first Headphone D corresponds to Auto Mute.

And the PCM control is active (try to increase it)?

Looks like my patch added some functionality, but not enough...
