"No Audio Output" on Yoga 720

Hi! My new Yoga was working great. However, suddenly the volume does not work. When I hover over the sound icon it says "No audio output device is installed". When I click on the sound icon it immediatley takes me to a box taht says "detecting problem" and then no problem is detected. I need help please!

 

Thank you!!

Re: "No Audio Output" on Yoga 720

Hi missw,

 

Welcome to the Community Forums.

 

Did you notice any changes before the issue happened like Windows updates?

 

Initially, try to fully shut down the laptop and turn on using the Novo button (item7 page 75) to access the BIOS menu.

On the BIOS screen, load defaults pressing FN+F9 then FN+F10 to save and exit.

 

If the same issue then you can take the option to jump back to the previous date using system restore choosing a restore date before the event occurred.

 

Else uninstall and updating the audio drivers from the support site can be the next step.

 

I was checking on related "No Audio Output" issue on yoga machines as Yoga 720 is not listed as part of the cascade list but an option we can take if the above steps fail: Audio device disabled after Windows Update – Yoga 510/710, Flex 4 1480/1580 and ideapad 310s/410s/71...

 

Update us how it goes.

 

Regards

Re: "No Audio Output" on Yoga 720

Thanks for the tips. I'm having a hard time enting the BIOS menu. I don't understand what to press. I tried the second option and it said I had no previous dates to go back to...

Re: "No Audio Output" on Yoga 720

Hi missw,

 

Greetings.

 

Would you be able to try the solution from this tip?

It would include Intel(R) Smart Sound Technology (Intel(R) SST) Audio Controller from the device manager.

 

Novo button (item7 page 75) to access the BIOS menu (click on the highlighted term).

Else on restart press FN while tapping on F2 for the BIOS.

 

Update us how it goes.

 

Regards

I'm having the same problem. I tried troubleshooting to no avail. Purchased less than 30 days ago so took it to the Geek Squad. They suspect possible cause is MS latest update. They tried several fixes, including those listed below but could not fix so keeping for more testing! Bummer.

Re: "No Audio Output" on Yoga 720

Same thing happened to me twice. Most recently tonight. I can't remember what I did the first time but I think I had to download a sound driver (realtek?). Regardless, this is an issue that should never happen. Why is this happening in the first place. Is starting me regret venturing away from Apple to get a windows based machine and my first lenovo. Not a good first impression. If this keeps happening, I'm considering dumping my Yoga and getting a macbook

Re: "No Audio Output" on Yoga 720

I tried this tip (It would include Intel(R) Smart Sound Technology (Intel(R) SST) Audio Controller from the device manager.) and it did work for me. Problem was I experienced no sound BEFORE any updates. After the updates and reboot, it still did not work until I tried this tip. Afterwards, I rebooted and it worked. 

 

Frustrating to say the least

And we're back...
