Summary

This issue exists on a new Intel NUC machine I'm working with. Everything works fine with my older NUC. The issue is that once the AMD machine wakes from sleep, audio stops working after 14 seconds of playback. I am testing on two Intel NUC machines. One is completely Intel (integrated video) the other has an integrated AMD 540 video card. The AMD one has the issue. No problems with playback until after the machine wakes up from sleep. It will play all videos fine, but audio only plays for about 14 seconds, then cuts out.. plays again for a second, cuts out, etc. Do you have any idea how I can trace the cause of this down or what workaround I can add to the AMD machine to get around this? Tried switching audio tracks, same issue. A reboot solves it.

Tested and VLC does actually do the same thing, but other video sources (tested with YouTube) do not.

Is the Video card the only difference between the two machines? Do they have the same Audio card?

To try to debug this, you can add -vv and see if there is any issue there.

If your issue also happens on VLC, I'm afraid I can't do anything for you on this project.

Where do I add the -vv? When testing in VLC or is there a place for it in Vlc.DotNet?

[jeremyVignelles]

-vv is a command line argument you can give to vlc.exe and pass to VlcMediaPlayerOptions in Vlc.DotNet.

It does the same thing as changing the verbosity level of the Messages window in VLC : it gives you verbose logs.

Ok, thanks. The log didn't reveal any errors or indications of audio issues so it has to be related to the AMD driver. The audio card is not the same - it also uses AMD drivers. Looks like I'm out of luck.

[jeremyVignelles]

Please send the log files from both computers. You can also use -vvv for an extra level of verbosity, but not sure it changes anything though.

EDIT: Can you also check if the prerelease of the VLC 4 application has the same issue?

I decided to just disable sleep. I tested the machine and it uses like 12W while idle which I can totally live with overnight. I'm convinced it relates to AMD's drivers and I just don't want to spend time debugging their stuff. Thanks for the help.
