[. . . ] Check BIOS setup if "AC97 Audio" is enabled. If sound already installed, check our website for an audio driver update. The sound is working in my system, but when I play CD music from the CD-ROM, I do not get any sound. This is because the 4-wire audio cable from the CD-ROM to the on-board CDIN connector or AUX connector on the M/B is not connected. The sound and everything else works fine except that the recorder and microphone do not work. [. . . ]
