Froghut 3 Posted June 5, 2017 Share Posted June 5, 2017 Hi, When I play back certain video files and try to adjust the volume nothing happens, the volume stays the same even though I change the volume settings. Even when trying to change the volume in the Google Home app it still does not change at all. Here is the media info for one of the videos where that happens: VideoCodecH264AVCYesProfileHighLevel41Resolution1280x720Aspect ratio16:9AnamorphicNoInterlacedNoFramerate23.9760246Bitrate4615 kbpsBit depth8 bitPixel formatyuv420pRef frames1NAL4 AudioLanguageengCodecEAC3Layout5.1Channels6 chBitrate640 kbpsSample rate48000 HzDefaultYesTitleEng Dolby Digital+ 5.1 Default Container is mkv. 1 Link to comment Share on other sites More sharing options...

Luke 36991 Posted June 6, 2017 Share Posted June 6, 2017 @@Froghut, we are using audio pass-through to send ac3 to your tv or receiver. when this happens you need to use the tv or receiver to control audio. That's why this happens with some files and not others. When audio passthrough is not used, like for aac or mp3 audio for example, then you'll be able to control with the Emby app. Does this make sense?

Froghut 3 Posted June 6, 2017 Author Share Posted June 6, 2017 Yes that makes sense, thanks for the explanation! But I have to say that is really not desirable for me, I would like to be able to always control the volume from within the emby app. Is there a way to force audio conversion as a "workaround" or something like that?

Froghut 3 Posted June 11, 2017 Author Share Posted June 11, 2017 *bump* Any plan to change this behaviour, or to add an option to force transcoding as a workaround? Link to comment Share on other sites More sharing options...
Luke 36991 Posted June 12, 2017 Share Posted June 12, 2017 Ok I think I was actually wrong about this. I tested this with google home and I am not having any trouble changing volume when passing audio through directly to receiver. Link to comment Share on other sites More sharing options...

Froghut 3 Posted September 13, 2017 Author Share Posted September 13, 2017 Sorry for bringing this up again, but is there some kind of estimation on when this bug will be fixed? It is just really annoying to watch something on chromecast and not being able to control the volume of some content. Link to comment Share on other sites More sharing options...
Froghut 3 Posted November 16, 2017 Author Share Posted November 16, 2017 This is still not working. I use my TV only for watching stuff via Chromecast and use my phone's IR to turn it on/off so I don't really use my TV remote at all, that's why it is really annoying that volume controm from inside the emby app is not working. In all other streaming apps (Netflix, Plex, etc) this works. I really want to love Emby but this is incredibly annoying. Link to comment Share on other sites More sharing options...
Froghut 3 Posted January 6, 2018 Author Share Posted January 6, 2018 I just noticed Emby on Chromecast will now give a notice when volume control via Emby is not working. This is nice, but wouldn't it be possible when this is detected to instead force transcoding with an audio codec that supports volume control? If I force low quality on chromecast streaming it gets transcoded and no longer dirct streamed - and then volume control works. So instead just transcode with same video qulity but working audio?

Froghut 3 Posted January 7, 2018 Author Share Posted January 7, 2018 (edited) Oh, I guess it is a chromecast feature then, got a chromecast update a few days ago. I attached a picture I took. But anyway would it not be possible to force transcode on files with those audio codecs? Edited January 7, 2018 by Froghut Link to comment Share on other sites More sharing options...
Luke 36991 Posted January 7, 2018 Share Posted January 7, 2018 it's possible but we currently don't have a setting for that. so it's something we'd have to look at adding. it is certainly not something we would do by default because most people would rather avoid the transcoding.
