Updated from Windows 7 to Windows 8. Now I have only 2 channels audio out from HDMI.
Before the update 5.1 worked excellent. I have tested with several different drivers from you, such as 12.6 and 12.10. But no difference.

Same issue was reported below:

Topic Title: HD5450 - Missing 5.1 Sound in Windows 8

Please read the link below and submit a ticket to AMD so that it can be addressed and included in a future version release (assuming that they are still supporting the HD3xxx line-up of ATi promises though)

Reproducible issues can be reported here.
