I think this is not what I want. I don't want to combine the two sound cards. I want to route the audio being played on one sound card to the other sound card. I have found the following answer:
http://askubuntu.com/questions/168333/routing-sound-from-different-cards-to-a-single-output

So with the following line:

pactl load-module module-loopback source=<name_or_index> sink=<name_or_index>

I should be able to achieve what I want. However, I know no pulseaudio and I got some issues with it already. 

For example,
I start the pulseaudio with  

root at dolevo:~# start-pulseaudio-kde
W: [pulseaudio] main.c: This program is not intended to be run as root (unless --system is specified).

I guess it starts working properly after this call. However, I call

pactl list

to get the list of the devices but I get 

root at dolevo:~# pactl list
Connection failure: Connection refused
pa_context_connect() failed: Connection refused

So, what should I put as source and sink? I have already tried calling the following:

pactl load-module module-loopback source=hw:1,0 sink=0,3

However I again receive:

Connection failure: Connection refused
pa_context_connect() failed: Connection refused

I would appreciate if you could help.
