- Yes. We opened a ticket for the problem, and Microsoft was able to provide a resolution for us. I don't know whether they did something to apply just to our tenant or might apply for all.
As part of the solution, we were asked to re-upload the videos after they made some change somewhere. (Meaning when I opened this thread back in in May 2023, re-uploading or uploading to different places never helped. But after they made a change and asked us to re-upload, the audio definitely did start working. For some videos, the only copies we had were in SharePoint, so downloading then re-uploading did also work.)
I don't know if that will be helpful or not - I was reluctant to update the thread since I didn't know if it was a fix just for us or more globally. I'd suggest you try a few files and see if re-upload helps. If not, then open a ticket for sure.
I should be more specific: MP4 just being the container, what seems to be the actual problem is the audio codec used, as the video just plays fine. My problematic files seem to use AC3 (Mediainfo is a useful tool to check this out), which is not supported by the new improved video player (as per the link posted above). If I stick to codecs recommended in the tip box when I recode the files with Handbrake, the play just fine. Still a hassle.
What's also gonna be a hassle is downloading and then re-uploading the files if MS support actually can fix the issue upon request (as described by anneoday above). I've yet to do this.
MicrosoftNeven Wenger Thanks for sharing the input on your experience, Neven. Audio and video codecs outside of the list documented at the following link are unsupported and result in either no audio or video - see Video formats you can play on the OneDrive website - Microsoft Support
Our team recognizes there's an existing gap in codec support and are working to ensure parity with Classic Stream which supported some of the codecs mentioned on this thread (e.g. Dolby AC3). I don't have an ETA to share yet, but we are aware of this problem and working to provide a solution.
