According to 1 in lower bit of misc in pins configuration:

hdac0: nid 27 0x0221451f as  1 seq 15    Headphones  Jack jack  1 loc  2 
color   Green misc 5

your hardware vendor tells that pin 27 (and most of others) does not 
support jack sensing. If you said it is working, then he is incorrect 
and you can fix this with device hints like
hint.hdac.0.cad0.nid27.config="misc 0"

I am not sure what happens now if redirection is requested and there is 
no sensing support. May happened then one or another output will be 
muted as in your case. I need to check that.
