No audio through internal speakers

2015-06-21, 19:44 PM

I purchased a new T550. From the start I noticed audio problems: The speakers produce a click sound in regular intervals when sound is on, but otherwise no sound comes whatsoever. The click sound disappears when I mute. Is it a hardware problem and how do I solve it?

Hi Makumba,

 

Welcome to Lenovo Community!

 

  • Are you getting same issue when you connect any external speaker or headphone?
  • May be this could be driver issue also, did you check with uninstalling and reinstalling the Audio driver once?
  • You can check downloading the latest driver from the below link.

Hope this helps.

 

Best regards,

Hemanth Kumar

I get the proper sound through the headphones and also through a USB device. But when I unplug, there is no sound from the speakers. I have never heard any sound at all from the speakers, except the occasional soft clicks, which come from the right speaker. The left one is totally mute.

 

I have tried to uninstall and reinstall the drivers, to no avail. The Realtek High Definition Audio shows under the playback divices and is marked as working properly.

 

Thank you for your response!

Makumba

I uninstalled/reinstalled the old driver and also downloaded the new driver,
to no avail. Headphones work = I get the proper sound through headphones.
Also a USB audio device gives me proper sound. But the speakers remain mute,
except for the occasional soft clicks that disappear when I mute the system.
The Realtek High definition audio is listed properly as default playback
device and marked as working properly.

Could it be a mechanical fault?
