Low volume on left side of both headphones and computer speakers

The other day I realized when listening to audio that the volume on the left side was significantly lower through the headphones on my U400. I checked and this problem also exists through the computer speakers. It does not appear to be a problem when I tried it using the hdmi port to my TV as a test.

I've played with every audio setting I could find in Windows 10 and have uninstalled and reinstalled numerous audio or audio-related drivers. I've also tried different audio programs (iTunes, Skype, Media Player, etc.). Nothing seems to have had much effect on the issue. I've tried settings such as the volume equalization, changing the balance settings, disabling and enabling enhancements. 

The only thing that appears to somewhat address the issue is when I lower the volume on the headphones (with the volume control on the headphone set). At some point that seems to allow both sides to be equal, but the volume is much lower than I'd like. 

Any thoughts as to what the problem might be related to would be much appreciated. I find it interesting that the problem doesn't appear (to me) to be related to the external jack because the same problem occurs with the computer speakers. However, there is no problem as far as i can hear when I use the digital hdmi connection.

Thanks

Re: Low volume on left side of both headphones and computer speakers

Thank you for your response.  Everything I've read about sound card issues indicates that faulty sound cards are rarely the issue with audio problems.  They are usually issues with the audio drivers.  Of course I would never expect a problem with an integrated sound card on a Lenovo product.  It wouldn't speak much to the quality of the product.  And, it ceratinly would be cost-prohibitive to have it reaired if the problem is in the hardware.  

 

Can anyone recommend a method or tool to test or repair the sound card or audio driver?  I've uninstalled and reinstalled the audio driver (Conexant SmartAudio HD --version 8.54.42.0) with no improvement to the problem, and I've tried Microsoft's High Definition Audio Device 10.0.14393.0 driver and that did not help either.   I currently have the Conexant driver in place.

 

Thank you.   Dennis
