serpi 72 Posted June 9, 2019 Share Posted June 9, 2019 Hi, I've just installed a new HTPC (Intel NUC, i3 7100U, W10 64 Bit 1903) and for now, I've installed only the latest gfx driver and Emby Theater. There is now a strange problem: When I enable frame rate switching, it plays no sound, the output for nerds also looks strange: The same video without frame rate switching plays with sound and looks healthier: This happens on all videos, as it seems. I'm not using passthrough. I think, this is really strange, any ideas on this? Ciao, Alfred Link to comment Share on other sites More sharing options...

Guest asrequested Posted June 9, 2019 Share Posted June 9, 2019 Well, you could try adding this in your mpv.conf audio-stream-silence=yes Link to comment Share on other sites More sharing options...
serpi 72 Posted June 10, 2019 Author Share Posted June 10, 2019 This didn't work. I enabled logging when trying to play a video with frame rate switching in mpv, the file is attached. The two extra lua script do not harm, I just added them, it also didn't work without them. It seems, mpv has problems after frame switching to obtain the sound device, so I found this line: [ 1.166][e][cplayer] Could not open/initialize audio device -> no sound. I disabled and enabled exclusive audio device, this doesn't help anything. So it might be some problem with the frame rate switching script.

Guest asrequested Posted June 10, 2019 Share Posted June 10, 2019 Yeah, there seems to an issue with some devices. I reported it a while back. https://emby.media/community/index.php?/topic/65730-no-sound-with-refresh-rate-switching/ Link to comment Share on other sites More sharing options...
Guest asrequested Posted June 10, 2019 Share Posted June 10, 2019 What you can try is use mpv on its own, elevate the logging to trace, play a video and manually change the refresh rate in Windows. If the sound fails, then look at the log. The log will be huge. You won't be able to use trace logging in theater. For some reason, playback won't start with anything above debug.

serpi 72 Posted June 10, 2019 Author Share Posted June 10, 2019 No problems with Kodi (18.2) and frame rate switching on the same device... I will move the box soon to another TV, maybe that will change anything. Link to comment Share on other sites More sharing options...

Luke 37046 Posted June 11, 2019 Share Posted June 11, 2019 Are you sure that your mpv.conf file is being used? Link to comment Share on other sites More sharing options...
serpi 72 Posted June 11, 2019 Author Share Posted June 11, 2019 It used the log-file entry in it, so I would say yes, it is used. I can see nothing about the audio-stream-silence in the log file, so I don't know, if this is used. But doofus discribed the problem already in posting #6, so it seems, it's nothing new and seems to be related to Intel NUCs?! Seems like mpv (or the frame rate switching script ot the RefreshRate.exe) does not correctly reset the audio device when switching framerate. Sound does work, if there is no frame rate switching, for example, when screen frequency already matches video framerate, so it's not the option itself, does make the problem, but the switching. I only have this problem now on my new NUC (Intel with i3 7100U), not on my old one (Vorke P1 Plus with Intel Celeron J3455), both with integrated Intel graphics.

Guest asrequested Posted June 11, 2019 Share Posted June 11, 2019 Did you try what I suggested using the standalone and elevate the log level to trace? msg-level=all=trace Link to comment Share on other sites More sharing options...

Guest asrequested Posted June 11, 2019 Share Posted June 11, 2019 (edited) Nope, not yet. I was able to reproduce the issue in that way. No scripts. I determined that it has something to do with the device (the PC). I never ran a trace log, and I can't test it anymore. So maybe the the trace log will show something and then you can report it to mpv. Edited June 11, 2019 by Doofus Link to comment Share on other sites More sharing options...
Guest asrequested Posted December 1, 2019 Share Posted December 1, 2019 And for logging, this line should be better. msg-level=ao=-v -v Link to comment Share on other sites More sharing options...
Dave3000 3 Posted December 2, 2019 Share Posted December 2, 2019 In the near future I might be buying a Nvidia Shield TV Pro but I'm still not sure if I should buy Premiere lifetime especially that Premiere lifetime is on sale right now at a $20 discount. Does the Emby app on the Nvidia Shield TV have this same issue with no sound during playback when frame rate switching is enabled? Link to comment Share on other sites More sharing options...

Does the Emby app on the Nvidia Shield TV have this same issue with no sound during playback when frame rate switching is enabled? I don't use that on my Shield, but I'm pretty sure it works correctly. And this is only an issue with Theater on a few low end PCs. Link to comment Share on other sites More sharing options...
