    HELP - ASRrock 970m pro3 - Front HD Audio

    Hi guys, noticed a problem with Front Panel HD Audio Connection on motherboard.

    The Ground pin and Precense Pin are meant to be in a loop (connected to each other with the Front HD Audio cable). But it is causing the Audio IC to stop working (Win detects an error and put Red X in speaker icon). If I disconnect those 2 pins, then audio chip works as normal (Win shows Volume slider).

    Mobo website shows nothing about how to connect the 2 pins, but other websites show that they must be connected. Well mine are stopping the audio controller if these 2 pins are connected.

    Is there an issue with the board ? Any fixes for it ?
    Or shall I just leave Presence pin disconnected ?

          Help troubleshooting an audio problem with an RCA SGT-250 CED Player
          by samson7point1@yahoo.com
          The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

          The player processes the audio signal using two different reference frequencies. The "R"...

          by ChaosLegionnaire
          so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!
