Nouveau HDMI sound plays only on same monitor

in ubuntu 13.04, 12.10, 12.04 with nouveau drivers

ubuntu can play sound on HDMI (ok)

but didn't work change select/change on what HDMI cable/monitor should sound go

sound goes always on same monitor, is imposibble to change it to another (second) monitor)

see enclosure sound play always from left monitor if is selected HDMI /DisplayPort3 and from left monitor if is selected HDMI/DisplayPort 2
