Hi . I have a Sony Vaio laptop, It was working just fine but when I turn on the computer again it was already on mute. so I tried to un-mute it and it didn't un-mute . And When I turn the volume up it only goes up by one and wouldn't go up farther but still, it's mute
so I went on sound mixer and it said "no audio device is installed"
can you please help me ??

Hello,

it sounds like you have lost your audio driver.

Can you confirm this by right-clicking computer and selecting manage

then go to device manager and you should find your audio driver with a yellow triangle next to it.

you could try right clicking it and selecting update driver.

or

go to Sony support website and select your computer model number and download the audio drivers.

you've got nothing under audio inputs and outputs?

is your sound a card or is it onboard the motherboard?

Hello, I recently experienced no sound on my laptop and I couldn't understand why. I tried all the quick fixes I found online and nothing.

Transfering sound from laptop to TV with HDMI

Hi,

I have a Dell Studio XPS laptop and I am trying to convert what I watch on my laptop to my television using an HDMI cable. The picture transfers fine, but the sound is an issue.

I have already changed my default sound to the HDMI cable under the control panel but it still sometimes plays from the computer. Every now and then I can get the sound to stop playing on the laptop, but then the sound continues to just not come out of the laptop or the television.

Please help me!
