No sound to HDMI Tags: Homebuilt HDMI Systems Last response: April 26, 2010 4:40 PM in Systems Share nojob April 26, 2010 3:44:14 PM Asus M4A79XTD EVO mobo with onboard audio AIT Radeon 5770 connected to TV by HDMI Win 7 professional 64 bit I installed latest software from Realtek. The HDMI on the 5770 is not recognized by realtek software. Thus, no sound from HDMI to tv. Sound works OK through speakers. The HDMI cable is OK. The 5770 is not one of the video cards that is listed as compatible with the mobo. Will a sound card power the sound to the HDMI on the 5770 through the mobo? If not, what options do I have? TIA. nojob More about : sound hdmi shortstuff_mt a b B Homebuilt system April 26, 2010 3:48:42 PM You just need to install the latest drivers from ATI for your 5770 then go into the sound options and select HDMI audio as the default audio device. m 0 l nojob April 26, 2010 4:40:51 PM shortstuff_mt said:You just need to install the latest drivers from ATI for your 5770 then go into the sound options and select HDMI audio as the default audio device.
