ebr 14925 Posted July 17, 2019 Share Posted July 17, 2019 Regardless, why does it only happen in Emby? Are the other apps you are testing against actually switching between a bitstreamed DD signal and a straight stereo signal? At this point, that would be my guess as to why it is different. Changing the setting I referenced above would stop Emby from doing this switch as well but we need someone to confirm that has an effect. Link to comment Share on other sites More sharing options...

Thats when the drops occur, not stereo. The 2 videos I posted show exactly what's happening. In the first one it switches from DTS to DD and the last 2 seconds of the commercial drops the audio. Edit: changing to stereo will fix it because now you are maintaining one audio codec. You shouldn't have to sacrifice audio quality to stop it though.

ebr 14925 Posted July 17, 2019 Share Posted July 17, 2019 Okay, so you see your receiver actually switch instantly between DTS and DD? I've never seen my receiver able to do that. It always mutes itself for a second or so between switching like that - much like a TV does on a refresh rate switch. Link to comment Share on other sites More sharing options...

ebr 14925 Posted July 17, 2019 Share Posted July 17, 2019 Okay, "Dolby Surround" is just a post-processing setting being applied by your receiver to a stereo input I'm pretty sure. Which app, exactly, is able to affect this switch instantly (and you can see the switch on the receiver display) with no drop-out? Link to comment Share on other sites More sharing options...

Which app, exactly, is able to affect this switch instantly (and you can see the switch on the receiver display) with no drop-out? My receiver is set to auto which takes the signal from the station and decodes it. Thats why its switching from DD to DSUR. The receiver is not changing or upmixing any signals. Thats what's being sent from the station. If you watch video 2, Plex switches between them instantly without dropping audio, and you can see the switch happen.

ebr 14925 Posted July 17, 2019 Share Posted July 17, 2019 Okay, "Dolby Surround" is post-processing being applied by the receiver so that makes sense now. Is Plex direct streaming the signal while we are either transcoding or remuxing it? Link to comment Share on other sites More sharing options...

When we direct stream, though, we are still passing it through our server but if it isn't remuxing then that shouldn't matter... Link to comment Share on other sites More sharing options...

Sammy 738 Posted July 18, 2019 Share Posted July 18, 2019 Possibly. The other streams may not have been switching in and out of DD. The Audio option is in the playback settings in the app. But then all content is stereo including lossless multi track?

So, if you use Emby to record the exact same channel and do not convert or post process the recording in any way, this problem doesn't occur? Does the audio switch like it does with Plex or has the audio somehow been changed? Link to comment Share on other sites More sharing options...

Does the audio switch like it does with Plex or has the audio somehow been changed? Its been a while but I do not recall it dropping out during the recordings. Its still switches audio from DD to DSUR. I haven't used Emby since the delete button situation but since that's being resolved I will put it back up and record some shows. If you can give me a day or so I will get some stuff recorded and see what happens. if it does indeed drop out on recordings I will send you a link to download the file. This happens on multiple receivers of multiple brands btw. I originally thought it was a Denon issue. Link to comment Share on other sites More sharing options...
TylerV76 84 Posted July 22, 2019 Share Posted July 22, 2019 Got around to checking this out last night and it is indeed dropping out during recordings every time the audio switches. I probably never notices since I skip through the commercials. I've sent you a link to the recording ebr. Link to comment Share on other sites More sharing options...
ebr 14925 Posted July 22, 2019 Share Posted July 22, 2019 Thanks for the sample. As expected, I can reproduce what you are seeing. Interestingly, in this recording it is just the random commercial that has a 5.1 signal so it is between some of the commercials that it happens. The main show is in stereo as are most of the commercials. I'm not really sure what to try here unfortunately. Every advanced receiver I have ever used has behaved this way - muting itself as it switches between different types of inputs. On my Pioneer, I can also hear the relays click as described here. I'll try to research if there is any way from the app side that we could eliminate this (aside from only sending stereo) but I don't have any ideas at this point.

Some stations are obviously worse than others but the ones who switch constantly between commercials are really aggravating. Im not sure how the HDHomerun app or Plex handle it but for some reason they have a smooth transition. Link to comment Share on other sites More sharing options...
ebr 14925 Posted July 22, 2019 Share Posted July 22, 2019 Can you please try turning off all post-processing ("surround") modes on your receiver and putting it in "pure direct" or whatever mode will just pass thru exactly what is being received without any other processing? Alternatively, does your receiver have any lights or other display that show exactly how many channels are being received? My Pioneer has little light boxes for all 8 channels and they light up based on the incoming signal. Link to comment Share on other sites More sharing options...
