The AMD HDMI is ONLY for HDMI audio and not for regular PC audio. Unless there is an HDMI cable plugged in, you will get the no cable plugged in notice.

Please post the motherboard manufacturer and model number. Without that I can't say what sound is on the PC's motherboard (for regular PC audio). But, if the PC audio is enabled in the BIOS and is Windows 7 compatible, Windows would install the generic, basic function, HD Audio Driver (Codec) and the PC sound would work. If the sound chip on the motherboard is not Windows 7 compatible (an old Win XP hardware) you will have to install a sound card to have PC audio.

The DX Diag, because the sound is not there, does not help.



Hello, Im having same problem, no sound to my TV, I did a custom build using gigabyte mobo 78lmt-usb3 5.0 version , Im running windows 7 ult x64 and my sound does work but only after i restart my computer or simply just unplug and plug back in my HDMI cable but the sound goes away when i power off my tv and then back on, when i power tv back on i get the AMD HDMI is not plugged in and it is grayed out also a red X on my speaker icon in lower right hand corner, i have installed every driver update I even called and was in contact with tech support from gigabyte and they claim they cant get the problem to duplicate on their end, they sent me out a new board but same exact problem, and yes ive done all the obvious, new cables, plugged into diff TV im stuck and need help
