I have a user whose audio keeps cutting out on his Lenovo X1 Carbon 20A7. I've written a simple .bat file to restart the Windows Audio service, but this is only a temporary measure.

So far we have done every update known to Lenovo and Microsoft, including a BIOS update.

I've also had the motherboard replaced (which solved the issue for about 3 weeks).

This has had 6 people edit it now, either help or move on please!

  • Not much to go on. What's the motherboard? Is the user using a dedicated sound card? Is the PC on a surge-protector? Is the PSU old/low-quality? Fluctuations in electricity supply frequency can cause sound cut-outs. Is it the sound that's cutting out or the audio service that's stopping? – RJFalconer Feb 23 '16 at 17:15
  • @RJFalconer sorry thought I put that in there, have updated now, it's a laptop X1 Carbon 20A7 – David Golding Feb 24 '16 at 9:32
  • Did you check the eventviewer for relevant events? – Smeerpijp Feb 24 '16 at 10:46
  • yeah nothing special or audio related the occasional USB issue but not in the same time frame as the audio outages. – David Golding Feb 24 '16 at 17:55
  • Is the problem that the audio service stops, or does the sound cut out for another reason and restarting the audio-service fixes the problem? (Btw superuser and the other stack-exchange sites all operate with an emphasis on community moderation; it's common for your question to be edited for tags/tone/clarity. It's nothing personal) – RJFalconer Mar 1 '16 at 12:44

I don't think I have an answer to your case. In my case, the Windows Audio Service was being stopped / stopping, by the Windows audio "Diagnose the problem" tool.

I restarted the computer, ensured Windows Audio was set to run "Automatic" and I manually ran Windows Audio service. After doing these, the Windows audio diagnostics ran clean and detected no issues.

But still, no sound!

I have a dock for my laptop. I un-docked and re-docked and then sound started working. Oops!

Just posting in case it could help someone else.


Here I am 2 weeks later with the same problem. My services.msc (aka Windows Services Manager) shows that the "Windows Audio Service" is stuck at "Stopping" status. I couldn't "Stop" the service nor "Restart it", so I followed these instructions . I'm paraphrasing:

  1. In Windows Service Manager get the name of the service (in my case, the name of Windows Audio Service is Audiosrv
  2. Open a command prompt: Use sc queryex {name_of_service}; in my case it was: sc queryex Audiosrv; note the Process ID
  3. Open a command prompt in admin mode, and kill: Use taskkill /f /pid {process_id}
