Both rear channels goes to RL speaker (5.1)

Got a problem with 5.1 output, my RR speaker keeps silence. With

speaker-test -c 6

I've understood that both RR and RL goes to RL speaker.
pulseaudio removed, asound.conf is empty.
aplay -l output:

Could it be that RL/RR jack is connected to Center/LFE? Test your 'side' device, if nothing comes out, jacks may be mapped/connected differently/wrong. I would also double check wiring, especially jack connectors. What devices do you have defined (aplay -L)? Did you test those?

Nothing wrong with connectors, everything works fine under windows. It worked fine under arch too, but I don't quite sure when it's gone wrong.

Re: Both rear channels goes to RL speaker (5.1)

Check what you upgraded/updated lately (PulseAudio upgrade to 5 brought some problems for several users, for example). Here is some information on surround mapping channels in alsa. You could try remapping in alsa, although I doubt alsa developers would just change surround devices, unless it is a new card. You provided so little information, that I can only speculate.
