First from all, I intend to use 5.1 sound surround system. In my case there are only maybe 4 speaker playing, even that I see there is 5.1 profile configured. They are not muted. As temporarily fix I found it is enough, when I simply switch to different sound profile (for example 50) and then again to 51 - same one as previously configured. But after this re-switch, it just works as supposed. So it is clearly a bug, because it does not work after boot with same sound profile, but after switching to another and then back to 51 analog surround, it is fixed. It is possible to change such profiles by pacmd command too. Tested sound card is Sound Blaster X-Fi Xtreme Audio. Running Ubuntu 14.04, but this bug is present there for years. Interestingly, there are two sound cards reported in my system. #0 is HDMI sound card from NVidia card. #1 is Sound Blaster card.
