Creative Sound Blaster USB X-FI Surround 5.1 Pro SBX

Hi,
I use RPi3 with latest osmc build with external Creative Sound Blaster USB X-FI Surround 5.1 Pro SBX sound card. System recognise sound card and it is available to select in system audio settings. But there is problem: works only 2 front channels, independently to selected number of channels in configurations. When I connect to RPI via ssh and run speaker-test -c 6 -t waw -D surround51 all 6 channels works good.

Could someone help we with solving this problem or give some ideas?

Thanks

Are you sure the media you are trying to play provides multichannel track?

when I use desktop ubuntu with sound card, it sounds 5 channels independently from source, but with osmc it doesn’t
