No sound, video game controller in device manager. No audio full stop.

I was rudely interrupted during a truly hilarious episode of Curb Your Enthusiasm to the cruel sound... of silence.

I know this is an old problem, I've searched high and low for a fix for hours, but none seem to pertain to my specific set of circumstances. Any help would be great.

Situation as follows; watching media on VLC, audio stops, laptop goes all crashy, I reboot, still no audio, red 'x' on volume icon, troubleshooting results in message reading "hardware changes might not have been detected".

I check device manager to see whats going on, there is no sound/video/game line visible. There are no unknown devices, exclamation marks, yellow triangles or anything. I hooked in my external soundcard to see if that was ok an sure enough it showed up fine. But still no sign of the onboard Realtek one that came installed.

I go to the Toshiba website to try and get updated audio drivers for my model laptop but apparently the only drivers available since 2009 are a bluetooth stack, a bios update, and a DVD update checker.

I've tried anything I could based on others' findings and successes but still no joy.

My laptop specs are

Toshiba Satellite U300-15p PSU30E
Windows 7 Ultimate 64bit

I apologize to be yet another repeater of this same issue, but I can't figure it out and would be grateful for some assistance.

Cheers!

Thanks for getting back to me. I downloaded AC97 driver, installed and rebooted, to no avail. The laptop is 4 years+ old, could it be possible that the internal soundcard is dead?

Booting in to your BIOS, are you able to determine whether AC97 or HD Audio is turned on in your integrated devices (or similar) configuration?
If there is a known issue with the internal audio for your laptop, you may need to run the BIOS update, but only do this if it is listed to have solved all audio related issues in the update.

I'm unfamiliar with anything BIOS related... any chance you could elaborate on how I can determine what you asked?

Thanks again for the help.

Ok some updated info:

Turned on laptop this morning, the little 'searching for new hardware' icon in the bottom right corner was whirring away (this is a first since the problem started) and sure enough it was installing something to do with Realtek.

Now the little red 'x' over the vol icon is gone (yay), 'sound/video/game' shows up in device manager, and in its dropdown: 'Realtek high defenition audio' is there.... sounds perfect right? doesn't sound like anything actually... still no sound at all in fact

This is exactly what happened prior to the initial 'no audio output device' issue.

Anybody got insights into how I can resolve it?

Cheers!

Right, new update:

I restarted the laptop.... Now I'm back to square one. Read first in thread for details....

Are you certain your system requires the AC97 driver? I would think it would be the HD Audio one from Realtek.
Please try this driver:

Restart to complete the installation, and then double check your devices.

Problem solved. Installed that driver and rebooted; beautiful tinny laptop quality audio! Hopefully no recurrences now... Very grateful for your help amigo :)

Apologies to re-open the inquiry, but I've noticed that although the audio is now working, there is a very giltchy feel to the volume 'up/down' fader. When I click the vol icon and drag the fader up or down there is a delay of several seconds before the volume increases or decreases (about 15 seconds). Then the mixer/fader icon goes blank for a while...

Could this be related somehow? It's pretty laggy... Any further ideas?

Thanks again

I would recommend doing a clean install of the driver. That is removing the device and deleting all associated driver files with it (in device manager, ticking the box), and then installing the device driver and rebooting.

If it is actually just the Realtek HD Audio driver packaged for your laptop you may be able to install the latest Realtek HD Audio codec driver software from the Realtek website on top of your driver set... this might offer some better compatibility. Windows Updates might also populate something for your audio driver under the optional category.

To do this you only have to open up Device Manager and right click the audio device to click on Uninstall.

You'll be shown something like this. Tick the box as demonstrated in this image and then follow through with a reboot before you reinstall the drivers.
(Don't mind that I am on Windows 8. The instructions are identical.)

Hello again,

Followed all instructions but after rebooting, the red 'x' is back over the vol icon. Tried all of the previous suggestions again, plus the above to no avail. The only difference between your instructions and what I experienced was that there was no box to tick when uninstalling... don't know whether this makes a difference.

Current status is pretty much the same as the original: no audio, red 'x' over vol, no sound/video/game line in device manager...

Flummoxed!

Any idea where I go from here? Really appreciate all the help regardless of outcome.
