Hi, Here I go again with a new question. After some readings on the net, it's shown that a good sound card like X-Fi Xtreme Gamer is always better than on-board's Asus cards, even on newest motherboards like my P7P55D-E Pro [*]. Especially cause it safe some processor and memory ressources... If I plan to install such a card, can I disable the HDA Controller in the BIOS ? HDA Controller [Enabled] [Enabled] - Enables the High Definition Audio Controller. [Disabled] - Disables the controller. Thanks for your answers [*] If someone disagree, please tell me why.
