forcing two channel output

Please see verbose dmesg here:

I get 4 pcm devices and I understand their functions as following:
0. digital hdmi
1. analog rear
2. analog front
3. digital

It seems that when I use dsp1 sound goes to 4 jacks at the rear.
But I have only a simple stereo system connected to only one output.

Should I do anything?
Can I tell sound driver and hardware to not bother and route sound to only one output?
Should I simply disable the unused jacks (with as=0) or maybe split them off to
separate pcms that I won't use?

Thank you in advance.
