No sound on pc. Tried everything to fix.

Heres what I know and have tried.

My pc recognizes that my headset and speakers are connected. I can select and change the output between the two of them. It fails to play a test note when i attempt to. My Corsair vengeance pro wireless headset is also not playing the audio phrase when it fully connects to the pc.

I have re-installed and updated all drivers related to sound.

I have gone into services.msc and restarted both windows audio items and plug and play.

I have hard restarted the pc after each of these and all at once.

I have had this happen once before and it fixed itself with the only change happening being my headset fully charging. Not sure if its related at all but i let the computer sit and that was the only thing that had changed until i came back to sound working again.

Hi, please complete specs for your PC (see 'My computers' under my post for comparison) - 2 tutorials available if needed. About how old is it?


- how are they connected?

As you were prompted by the forum when you wrote the post (to save us asking), please post your build number.

History: (usually omitted):
- how long have you not had sound?
- what happened that might have led to this?
E.g. - update/upgrade/installation/ change of settings/ the cat walked over the keyboard..

Basic checks:
- run the Audio troubleshooter (rt click volume icon) and post a screenshot
To post a screenshot use the icon above your post, tooltip Insert Image. Tutorial available.
- post a screenshot of your Volume Mixer like this:


- post a screenshot like this:


- when you rt click the default device and click 'Test' does the green bar show movement- or nothing?

Do you have a relevant System Restore point?

Example threads:
No sound from speakers/headphones

I built the pc about 2 and a half years ago. Never had any problems like this until recently, my pc has been without sound for over 24 hours.

Hi, there are two problems indicated by the troubleshooter, and your default playback device seems inappropriate.
The troubleshooter may give more info: 'View detailed information'.

Again, do you have a relevant restore point as this has only recently happened? If so use that.

Otherwise: try resetting services and see if the troubleshooter shows that problem has been resolved.

Use Tweaking.com's free repair tool observing its preparatory stages.
(Google, download, install)
Choose only relevant repairs:
Reset service permissions
Set Windows services to default..
Restore important... services

Still no details of your PC or build number.

giving the tweaking service a shot, ill let you know how it works.
