Can't really work it out; I've tried speakers which I know work, and headphones, which I know work. I've gotten home from work and installed a new graphics card (580GTX, did not install the Nvidia hd audio driver), and now I have no sound. I get sound patterns on equalisers, so it suggests something wrong with my audio playback equipment, but it worked absolutely fine this morning.

Reinstalled sound drivers ofc, not sure what else to do; I really don't want to reinstall Windows just for this.
 
What version of windows?

Is the default playback device set to the sound card and not the graphics audio?
 
do you have another slot you can install the sound card in? this will make windows reinstall the drivers for the card in the new slot and should (in theory) clear up any not-so-obvious driver issues...

Had a similar issue on an old Socket A system, this sorted it - good luck :)
 
Uninstall the HD audio driver in Device Manager
Reboot

Disable audio in BIOS

Boot to Windows
Download realtek HD audio driver from here
Reboot

Enable audio in BIOS
Boot to Windows
Install downloaded driver

Also, there's no harm in letting the 580 install it's sound driver, you can just set your default audio as your onboard sound through Control Panel

If that fails, try a BIOS update

I've done most of that just not disabled audio in bios; part of me thinks somethings damaged the connectors because I hear a bit of a crackle when I plug headphones/speakers in, and as I said the equaliser seems to indicate sound is working, but no sound..

I realise there is no harm in installing the 580 audio drivers, I just removed them from the install options so as to not have extra stuff installed, as I won't be using the hdmi output.

Not entirely sure I can do a BIOS update, as its a prebuilt overclocked system from OcUK; might invalidate its warranty or just screw the overclock?

Click to expand...

If it works in Ubuntu, I can't see it being a hardware/damage issue.

The issue just screams that the default audio device is not set to your onboard sound/speaker output - especially with there being equaliser activity etc.

If you didn't install the audio drivers for the new card, do you now have a missing device driver in Device Manager?

I'd just install the driver and then make sure your default audio device is set to speakers/onboard sound. Disable the HDMI audio output in Device Manager if you really want to afterwards (it's hardly going to cause problems)
 
I've tried it both ways, with and without the hdmi output driver, nothing is disabled in device manager, no missing devices either way.

Had an interesting possible solution thrown my way; that the new graphics card is too powerful for the psu to power everything. Its a 600W psu, and the card does say minimum 600W..
 
Open the realtek manager, does it detect your speakers in the port?

Do you have a spare hard drive that you can test a fresh Windows install on?

-Try that fixing tool from MS that I linked to
 
Installed Windows again, no sound. Realtek manager detects speakers no problems.

Ran the tool, no problems found. Something very odd going on. Both my speakers and headphones can't just have stopped working...?
