Sound played fine via HDMI.
Driver installed and works properly per Windows.
Sound file played without any error.
Dell diagnostic test, no beeping sound when select No during the color bar display test.
At this point, I think the problem is with the hardware on the audio output end but not the sound processor itself.
I looked at the board and it seemed that I would need to replace the motherboard to fix this problem since there wasn't a dedicated audio module.
Could someone confirm or someone with the same experience chime in?
Thanks.
