T430 Sound failing intermittently

The sound is failing intermittently on my T430.

 

Closing then opening the lid to enter and return from hibernation sometimes restores sound. When this does not work restarting the machine usually restores sound. But the sound fails again after an indeterminate period.

 

Opening Ubuntu Linux in Virtualbox now displays the message "Some audio devices (PCM_in, PCM-mic) could not be opened".

 

I'd appreciate any advice.

Re: T430 Sound failing intermittently

Answering my own question in the absence of any advice from forum members . . .

 

I have established that sound works immediately after restarting the system but stops working after opening any application, Chrome, Thunderbird, etc.

 

Running Control Panel -> Sound -> Playback -> Configure -> Speaker Setup -> Test reports:


  This device is being used by another application

 

I would appreciate any advice on resolving this problem.

Re: T430 Sound failing intermittently

Under Sound > Playback > Properties > Advanced, is "allow exclusive mode" checked? Maybe try toggling the checkbox?

Thanks for your advice.

Yes, "Allows exclusive ..." was checked. I have unchecked it and I have
sound. I will monitor performance and report results.

This modification didn't work. I lose sound again a few minutes after a
system restart.

Re: T430 Sound failing intermittently

Since this problem appeared out of the blue I suspect a Windows update.

Googling "windows 8 update loss of audio" highlights a recent update
KB2962407. Uninstalling this update solves the problem.

Of course I now wait to see what other problems this unistallation
causes :-)

Re: T430 Sound failing intermittently

Did you encounter any problems from uninstalling? Did the problem go away for good? And can you explain how to uninstall that particular update please? Thank you.

Re: T430 Sound failing intermittently

I have this problem but with Windows 7 64 bit on my T430.

 

I also had the exact same problem some years ago with Windows 7 64 bit on a Thinkpad Edge E530.

On that occasion it nearly sent me to the mental hostpital and in the end I just uninstalled all the Lenovo software leaving just Windows 7. It left me with incredibly quiet sound and I never did figure out what Lenovo idiocy was responsible. 

 

This time I have noticed that setting power management so that the laptop stays at maximum performance even on batteries is also a make-shift solution.

 

Further solutions using Device Manager:

Once sound has died disabling and immediately reenabling "Realtek High Definition Audio" brings it back to life.

Also permmmmanatly disabling "Intel(R) Display Audio" seems to prevent any problems assuming you don't need display audio, which presumably is only needed if you want to connect an external display with speakers via the mini Display Port connector.

Re: T430 Sound failing intermittently

My OS is WIN7, so that no KB2962407 can be removed. How can I do?

This issue has bother me for a long time.

Does my suggestion of disabling "Intel(R) Display Audio" in Device manager help?
