Audio getting lost intermittently

Hi,

We are a company that bought two Macbook Air 2018 model. We have installed Windows 10 in both the macs. The issue is that Audio is getting lost randomly in both the machines. This happens once or twice every day and a restart solves the issue temporarily. Audio will be working for sometime and then all of a sudden, won't hear anything coming out of the speakers. No error messages are shown and it happens with all kinds of audio, be it the system notifications, playing youtube from a browser or using a media player to play audio files saved on the device. When the issue happens, if I plug a headset I can hear the audio. Likewise, if I had been using a headset instead of the inbuilt speaker when the issue occured, removing the headset will cause the sound to come out of inbuilt speaker. A restart solves the issue temporarily in all cases. This does not happen in OSX.

Here is what I have done.

Reinstalled Windows 10 in both machines.

Downloaded latest drivers using Bootcamp and installed them.

Reset PRAM.

Any idea what could be wrong and how to fix it?

Regards,

Avinash.

The issue has been reported to Apple support and they have escalated it to the engineering team.

Does an SMC Reset temporarily alleviate the Audio dropouts issue?

Today,I went to Apple Store(genius bar). I talked about this issue with staff.After all, staff said that Apple T2 had a issue.

Staff said, Will try to contact the engineer again.I hope find a solution...

There are quite a few issues with 2018 and later Macs which have the Apple T2 controller.

I suggest checking the Windows Event Viewer for any driver-related events.

Do you have any unknown/other devices in Windows Device Manager? Can you re-install BC drivers and test?

Most issues on 2018 and later models stem from the Apple T2 controller. You may want to talk to Apple Tech Support and see if they are aware of any known driver issues.

Thank you Loner, for your response. There are no unknown / other devices in device manager. All drivers are properly installed. We did a reinstall of boot camp drivers couple of times. We also tried reinstalling the operating system too but that did not solve the issues. We tried all of these steps in two macbook air 2018 that we have and both of them have the same issue. OSX was upgraded to the latest available version too, 10.14.3 which also did not solve the issue.

I have been chasing Apple support but yet to receive a solution. Got a call today saying that their engineering team is still researching this and that I should be on the lookout for any updates, windows or OSX and apply them to see if that solves the issue. Applied the latest available (10.14.3 supplemental) but no good. Hoping that this will be fixed soon as my company has more than one Macbook Air 2018 and all of them has the same issue.

Today,I tried call to Apple Support,but that problem was not resolved.The survey request seems to have appeared.I was told that I had to wait for updates and should use Feedback page.It will take time to solve it.I hope find a solution...

(In Apple's opinion, it was told that a lot of number of reports are required.)

I'm having the same issue on a MBA 2018 - Windows 10. I'm running BETA versions of OSX so any firmware released still has not fixed this issue, it's frustrating for sure, hopefully there will be a fix soon.
