T410s internal speakers fade out after a second, headphones work just fine

[ Edited ]

Hello Community,

 

My THinkpad T410, Type 2912-45G, Windows 7 (64bit) has a problem with the speakers.

 

Starting last monday (June 25th) my speakers stop working. When I boot the TP you can hear a static click through the speakers and it plays the windows sound for one second only. After the second you can hear another static click and the speaker stops working. Thats pretty much the way it is with all other audio content, when the TP is booted.

 

After pressing the Mute-Button or the volume-up or volume-down buttons the speakers will resume working for a second or so (still the static click, right before this second and afterward).

 

When I plug in my Headpones everything works fine. When I unplug my headphones, speakers do work again for another second.

 

I allready updated my BIOS, installed and uninstalled the driver, activated the sound-card (CONEXANT 20585 HD AUDIO), tried to update the driver. But nothing worked so far. I allready checked whether the switch in the headphone jack is stuck, but I couldn't find anything.

 

Did anyone experience the same or a similar problem? As the speakers do work for the mentioned second I assume, that the Hardware should be fine. As the headphones work properly the sound-card should be detected and istalled correctly.

 

I would really appreciate if someone could help me out on this. Sending the TP in (it is still whitin warranty) is going to be my last option since I need the TP for work.

 

Thank you very much.

Hi thecez,

Sorry to say that but it sounds like hardware issue. Please try BIOS and power management driver as well. If problem remain, please contact local lenovo when your machine is avaliable for inspection.

Hi Fred,

 

thank you for your reply. It somehow sounds for me as the only option, as I allready updated all drivers and the BIOS. I will call lenovo and see what they can do.

 

Cheers,

Alex

Did you find a fix for this? I have the same problem on a T410 running Windows 7, x64. Headphones work fine, but internal speakers drop out after 10-20 seconds. Adjusting volume or mute/unmute fixes things for another 5 seconds before audio drops out again. I've tried updating the sound driver and BIOS without luck.
