Hi,
Everytime my laptop starts up , AMD High Definition Audio Device doesnt show in list of Sound, video and game controllers , results in HDMI output doesnt show in list of playback devices . However , just when i set my lap to "Sleep" mode and turns on again normal mode , AMD High Definition Audio Device ,as well as HDMI, appears and works with no problems . And it also show "This device can perform faster" on the tray.
Please advice the solution.
My display adapters : AMD M880G with ATI Mobility Radeon HD 4250
Sound , video and game controllers when the computer have started up : IDT High Definition Audio CODEC
and after resuming from sleep : AMD High Definition Audio Device
IDT High Definition Audio CODEC
(both of them are up to date, i tried updating driver)
Operating system: Windows 7 32-bit
Thank you.
