Comment 15 for bug 1256511

After some amount of digging I found a workaround that worked for me.

I set up the desired sound settings in Sound control panel. Then I run:
pacmd list-cards
It turned out that my card index is 0 and my output profile is: output:analog-surround-51

Then I added the:
set-card-profile 0 output:analog-surround-51
set-default-sink 2

to the bottom of my /etc/pulse/default.pa

After restarting my machine, it woke up with correct sound settings. Now I know it's just a workaround and it's a shame that settings are not saved after changing it in the Sound settings UI.

Thanks,
Michal
