I got HP Pavilion G6 with AMD RadeonHD 6470M and AMD M880G with ATI Mobility Radeon HD 4250. If I want to install new drivers, everything goes right, but in the end of installation is problem with Sound Device HDMI and the installation fail and the integrated graphic is out of service. I tried block the integrated graphic before the installation, but it didn't change anything. The laptop works right with old drivers 12-1 version 188.8.131.52. Help me please, I have no idea what is wrong. If I can block the HDMI or some else. I never used it.
