This would be a way, but not a fully automatic one. I even found a
(German language) 'How-to'
(https://blog.natenom.com/2015/09/raspberry-pi-automatisch-herunterfahren-durch-spielen-einer-bestimmten-datei-in-mpd/)
that explaines how playing a prepared mp3 file (extra information in the
meta data) in MPD can be used to shutdown the raspi. But what I was
looking for was a fully automatic way - you put the record to play, go
to the place where you are listening and can forget about shutting down
the Raspi - until you need it again perhaps two weeks later.

I simply direct LMS (via iPeng) to a special m3u-playlist stored in LMS'
playlist folder that directs to the Icecast stream on the phono Raspi
("IP-ADDRESS"):
Code:

#CURTRACK 0
#EXTM3U

#EXTINF:-1,Phono
http://IP-ADDRESS:8000/phono

I understood that it's dsnoop that allows two simultaneous recordings
from the same capture device (which is what I would need to go the sox
way). But I get the same "busy" message using dsnoop instead of hw:1,0
