Sound hardware problems and trying to understand snd_hda

L

lasuit

I have an HP EliteDesk 800 and I cannot get line out audio to work. The internal speaker works, but that's all. When I search the dmesg for sound ports, these are the ones that look relavent:

Code: 
hdac0: <ATI RV930 HDA Controller> mem 0xf7c40000-0xf7c43fff irq 17 at device 0.1 on pci1
hdac1: <Intel Haswell HDA Controller> mem 0xf7d34000-0xf7d37fff irq 16 at device 3.0 on pci0
hdac2: <Intel Lynx Point HDA Controller> mem 0xf7d30000-0xf7d33fff irq 22 at device 27.0 on pci0

The output of /dev/sndstat is:

Code: 
Installed devices:
pcm0: <ATI R6xx (HDMI)> (play)
pcm1: <Intel Haswell (HDMI/DP 8ch)> (play)
pcm2: <Realtek ALC221 (Analog)> (play/rec) default
No devices installed from userspace.

It appears for a straight line out on the back 1/8 jack I will need to use pcm2. But when I look up the pins in sysctl this is what I get:

It appears from the output that the necessary pin is nid20 for line out rear jack. But, it's disabled! How do I enable it and make this work? Thanks for your help.
 
Does the following work? It should make the rear line-out the default output instead of the internal speaker.

/boot/device.hints
Code: 
hint.hdaa.2.nid20.config="as=1 seq=0"
hint.hdaa.2.nid33.config="as=1 seq=15"
hint.hdaa.2.nid23.config="as=2 seq=0"
