Well, here I am at my wit’s end (which isn’t really saying much, as I’m somewhat witless to begin with). I get no sound from my PC and am out of ideas as to how to find the cause of the problem.
The problem seems to have arisen a few months ago on moving day (!) but stranger coincidences have happened. Other than this issue, the PC is working flawlessly. It was playing sound (mp3 & CD) up to the point where I packed the system up and brought it to our new home. Within a day the machine was unpacked and everything except sound worked fine. Well before moving day and afterwards, no new software was installed and no changes to the system were made.
Here is the hardware information:
Motherboard: Epox EP-9NPAJ / 9NPA+ Ultra
On board sound: Realtek AC97, ALC850
CPU: AMD 64 3700+ (San Diego)
Here, in no particular order, are the things I’ve done/checked so far:
[li]Winamp, system sounds, etc. play no sound. They look like they are playing, but no sound comes from the speakers[/li][li]System is not muted, either in the system tray, when opening up volume control (and in advanced), in control panel, or in any of the applications I’ve been running[/li][li]Opened the case and looked for loose connections[/li][li]Speakers were checked on a CD player, they work fine[/li][li]Alternate speakers (Headphones, checked on a CD player as well) do not work[/li][li]I have no alternate sound card to try in the machine[/li][li]Nothing to note in device manager, no flags and all is supposedly working properly[/li][li]DirextX diagnostics do not make sound[/li][li]Reinstalled the drivers from the original install CD that came with the motherboard[/li][li]Ran the Realtek “Sound Effect” sound manager[list][/li][li]Its tests (i.e. speaker configuration, sound effects), appear to play but I get no sound[/li][li]When I run ‘connection sensor,’ it properly identifies either powered speakers or headphones on the line-out connector (green), but it also tells me to check ‘line-in,’ though there is nothing plugged in there. I have checked the connector for detritus, but there is nothing lodged in there[/li][li]When running ‘connection sensor,’ I hear a couple clicks from the speakers. This also happened when I first built the system, and sound was working properly.[/ul] [/li][li]I get no sound in Safe Mode (but didn’t expect any—apparently no sound drivers are loaded)[/li][li]I rebooted, disabled the onboard audio device in BIOS, had no audio present (i.e. not present in control panel, volume sliders grayed out, etc.), rebooted and turned it back on in BIOS—everything was present again, but still no sound [/li][/list]
So… now what? What else is there to check? Where do I go for from here?
