Lenovo B50-45 Audio Output not working

I have a problem with the audio output of my Lenovo Laptop. My laptop is about 2 years old and the audio output worked perfectly, I was able to plug in all kinds of speakers or headphones.

All of a sudden it is not working anymore. No matter which player I use, it always uses the internal laptop speaker instead of the external speakers. I also checked the drivers of my laptop, it tells me they are all up-to-date and no updates needed.

When I go to the sound settings of my laptop I can't even choose the external sound, it is not there anymore.

Can you please help me?

Thank you!

Re: Lenovo B50-45 Audio Output not working

Hello _Katrin

Thanks for using the Lenovo forums.

Try to download the Audio and Chipset drivers for the unit from the support page.


Make sure to reboot after an update on the unit.


Also, Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.
