Ok, it must be a control then:
amixer -c0 contents
We did try this already:

That was just the listing of the controls, no details.
[mythtv@seveneves ~]$ amixer -c0 contents
numid=19,iface=CARD,name='IEC958 In - Output Jack'
; type=BOOLEAN,access=r-------,values=1
: values=on
So it's read-only and it says it's on.
[mythtv@seveneves ~]$ amixer -c0 cset numid=19,iface=CARD,name='IEC958
In - Output Jack' on
amixer: Control hw:0 element write error: Operation not permitted
Tried the last two as root also with same results.
This isn't going to work, the control can't be changed.
I suggest that you file a bug in the kernel bugzilla. If you do, then
please either CC me or reply here with the link.
