Oh, I mis-understood the "Auto-Mute Mode" mixer enum as idle-related
thing. Trying it out, it works :)
I've not found the "Headphone Jack" control status within alsamixer
though I found it using amixer.
If alsamixer does not provide the information it would be a nice
feature to add reporting state of such controls.
If the information is already available I have not found it.
Thanks for the pointers and your support!
