Thanks for the quick reply! With the below patch the card starts 
successfully. I have now tested it on two machines and I'm using the 
"amixer contents" command to see the current jack status.

The jack state seems to be correct except in one occasion: at startup 
all jacks are "off", even though the machine was booted up with some 
jacks inserted. After having inserted or removed at runtime, the jack 
status is corrected.

In addition, I have a question about the second machine, which looks 
like this:

numid=45,iface=CARD,name='Front Headphone Jack'
numid=47,iface=CARD,name='Front Mic Jack'
numid=48,iface=CARD,name='Line Jack'
numid=41,iface=CARD,name='Line-Out Jack'
numid=42,iface=CARD,name='Line-Out Jack',index=1
numid=43,iface=CARD,name='Line-Out Jack',index=2
numid=44,iface=CARD,name='Line-Out Jack',index=3
numid=46,iface=CARD,name='Rear Mic Jack'

Would it be possible to name the Line-Out Jacks "Front Line-Out", 
"Surround Line-Out" etc, so one can tell which one is which? Or can you 
always tell that just from the order of them?

The alsa-info from that machine is attached.
