I am using an m8400f HP desktop. I have a set of Logitech speakers/sub and am using a TV/Monitor with built-in speakers.

My computer will occasionally register one or the other of the audio outputs, either the speakers or the monitor, but it is intermittent and unpredictable. In fact today the monitor played sound, but the speakers wouldn't, and in the process of getting the speakers to work, now neither will play. I do not often use headphones, but I tried those today to no avail.

Today I also went to RealTek's site and downloaded what I believe was a driver update for my soundcard, but I'm not 100% positive I have a RealTek card, the name just sounded familiar. I am unable to locate any setting in my Hardware Manager that will let me manipulate my sound card/drivers, it is though my computer isn't aware of any such cards. My little speaker icon in the taskbar shows a red X, not the mute kind, across it; when I open it to playback devices it currently shows nothing, although earlier it showed my monitor, speakers, and sound card. Like I said, it performs very intermittently, and I have not been able to figure out the cause.

I have searched through other forums, and have tried most everything short of opening my computer to look at my sound card. I do not know if it is integrated or may have a bad connection or what.

I would appreciate any insight.

Tried already checking the HP Troubleshooting link? http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01289551&lc=en&cc=uk&dlc=en

I looked over the troubleshooting, but none of the symptoms seemed to match the on-again off-again nature I'm dealing with. I checked inside my tower today, as far as I can tell the sound "card" is integrated to the motherboard. All I can see are the ports for the speakers.

Most likely a port or cable is faulty if reinstalling the driver did not fix the problem.

But would that account for why my PC won't even recognize any sound driver? And like I say, I'm using a TV monitor connected with an HDMI cable, plus my speakers; I would imagine with the redundancy in sound options, as long as my driver works, surely not both of the cables/ports are damaged?

I recently took advantage of my sound working to identify and update my driver; seemed to be the fix, but I booted up yesterday to no audio.

Is the video card for the desktop the GE Force 8500? The S/PDIF located for the card might be the missing link.
