Steps to reproduce
When using Microsoft Edge 15 browser on a Microsoft Surface Pro device, there is a problem with playing 3 or more audio files. The 1st and 2nd audio plays, however, the 3rd, 4th, etc. audio doesn’t play.
The same website or page works on a desktop computer using Edge and other browsers, as well as most tablets. I have only encountered this issue when using Microsoft Edge on a Microsoft Surface device. I have tried on multiple Microsoft Surface devices so I don’t believe there is a problem with the device other than it can’t play 3 or more audio files. No problems were found when troubleshooting the device.
This can be tested using the following website:
Copy the audio controls tag to duplicate the audio file 3 or more times.
Is this a known issue? We hope there is a resolution as this problem is affecting some of our e-learning/ online courses from being sold.

Hi Sophia. We aren’t able to reproduce your problem. There is a difference in how the first two audio streams are handled vs. the third or higher stream, but all should sound the same to you. The first two get audio offload so they render with less total system power consumption.
If you are still able to reproduce the problem on your device, please go to the feedback hub and take Audio traces while it’s happening, and attach them to this bug.
Thanks for reporting this concern!
Also, please try turning off audio offload to see if that makes a difference:
Right click the volume mixer
Click on “Playback Devices”
Right click on the playback device that is being used.
Click on “Properties”
Click on the “Advanced” tab
Uncheck the box next to “Allow hardware acceleration of audio with this device"
