I have just completed a new PC build using a Gigabyte GA-H77-D3H Socket 1155 VGA DVI HDMI 8 Channel Audio ATX motherboard:
This board uses HD audio by default, but I want to use my old computer case's AC'97 connector to the front speaker.
I cannot find any particular audio settings in the BIOS, except enable or disable audio completely.
There must be a BIOS setting somewhere surely?
I am using Ubuntu 12.04 but I guess that any Linux OS would have a similar problem.
When I connect the front speaker to the appropriate mobo header, I just get an unpleasant continuous noise.
Any suggestions on how to get AC'97 working?
