Yesterday I began to have trouble with the audio from my X1 Carbon Gen 6 speakers. The first thing I noticed is that the mute button on the keyboard was unresponsive: the light indicating that the volume was muted stayed lit regardless of wheather I pressed it. After fiddling for a bit, the problem rectified itself, but then I noticed another problem this afternoon.
Now no audio plays from the laptop speakers, regardless of whether the audio is muted or not. I have spent a long time trying to troubleshoot the issue, with no success:
* restarted windows
* ran Lenovo system update
* ran Windows update
* checked system volume controls
* checked program volume controls
* ran Windows audio troubleshooter
* disabled audio enhancements (including Dolby Atmos)
* changed default format under advanced audio properties
* deleted and reinstalled device driver software
* restarted Windows Audio service
* disabled Intel Display Audio in the device manager
I noticed a couple odd things along the way:
* When I went to restart the Windows Audio Service, the system reported the following error: "The following services are dependent on the Windows Audio service. Stopping the Windows Audio service will also stop these services. Lenovo Hotkey Client Loader"
* Each time I turn off the Dolby Atmos enhancements in the audio properties dialog, I find that the enhancements are on again once I restart the computer.
* When I try to restart the Windows Audio Service via services.msc (rather than an elevated command prompt, the system returns the following error: "Windows could not stop the Windows Audio service on local Computer. Error 1053: The Service did not respond to the start or control request in a timely fashion." Afterwards, the system is unable to restart the process.
* On one attempt, the speakers did not play audio from my mp3 program, but when I opened the Windows Sound Settings dialog the speakers began to hiss static. I initially muted them, but when I went to unmute them they were silent again.
* When music is playing and I press the mute button on the keyboard, the speaker pops very faintly.
Any ideas? This is quite frustrating.
