pcdery 1 Posted March 13, 2017 Posted March 13, 2017 Hi, when I try to listen a 720p MKV file with the new roku app, there is no sound, but when I start the SAME file with the old app, the sound is working. You have an explanation? Thank you.

ebr 15435 Posted March 13, 2017 Posted March 13, 2017 Was a transcode log produced? What kind of equipment are you using? Does it support Dolby Digital audio? How to Report a Problem
pcdery 1 Posted March 13, 2017 Author Posted March 13, 2017 I am using the new Roku Express+, connected via HDMI to the TV. But as I said, the sound is working when I play the file with the Old Emby Roku App, but not the New Beta Roku APP. So I think it is not my equipment the problem, but the new app. I will check toninght if there is a transcode log produced.
ebr 15435 Posted March 13, 2017 Posted March 13, 2017 The capabilities of the equipment are important because the new app asks the device what it can support and makes decisions based on that. That audio track is DD so if your equipment doesn't support DD then we should be transcoding to something else. Also, you might try changing the audio settings on the Roku itself.
pcdery 1 Posted March 13, 2017 Author Posted March 13, 2017 Ok, I will try to change the audio setting on the Roku itself. Here is the info I found for my Roku Express+ Stereo The Roku player by default will provide stereo signal, through both composite or HDMISurround Sound The Roku player does not process surround sound signals (only passthrough via HDMI). Surround sound requires a surround sound capable audio/video receiver (AVR) connected using optical or HDMI cables. Not supported using composite cables. Dolby Digital Plus (DD+) requires an AVR capable of decoding DD+ signal.
Solution pcdery 1 Posted March 14, 2017 Author Solution Posted March 14, 2017 I changed the audio settings on the Roku itself to STEREO, and now the sound is working. Thank you. 1
ebr 15435 Posted March 14, 2017 Posted March 14, 2017 Thanks for reporting back. Glad you got it going.
dcook 280 Posted March 14, 2017 Posted March 14, 2017 If it was playing fine on the old app, but not the new app, the OP should not have to "downgrade" his audio settings in the ROKU to Stereo, shouldn't the new app be able to detect the highest available audio output like the old app does? I don't think advising the OP to change ROKU settings to get around a bug in the new Roku App is the best course of action. The default ROKU audio settings should work with the new Emby Roku app, the same as they did with old Emby Roku App The new Roku App should be able to auto-detect highest audio and then select accordingly.
Jdiesel 1242 Posted March 14, 2017 Posted March 14, 2017 (edited) Unless I am mistaken it is not the Emby app that decides what formats are supported but instead the Roku firmware. Roku has been releasing some buggy firmware lately with lots of weird audio issues that are affecting multiple apps. I had my audio options set to HDMI and DTS, DD+ since I got my Roku and it was working perfectly, when Roku updated its firmware to 7.5.1 4111 my audio quit working in both Emby and Plex. I had to change both settings to Auto to get my audio working again. Both DTS and DD+ now play fine with Auto selected in the Roku settings. Edited March 14, 2017 by Jdiesel 1
dcook 280 Posted March 14, 2017 Posted March 14, 2017 (edited) That is what I meant, the Roku audio settings should be Auto, I would not advise to change settings to 2ch Stereo, as the App should try to play the highest quality audio available Unless I am mistaken it is not the Emby app that decides what formats are supported but instead the Roku firmware.

ebr 15435 Posted March 14, 2017 Posted March 14, 2017 My guess is that his TV only supported stereo which is why he got no audio when he had the settings set to force DD. The app can only go by what the environment tells it and I believe it is possible for you to make the environment lie to the app .
Luke 38825 Posted March 14, 2017 Posted March 14, 2017 If all other factors are equal, then you can try the zip installation of the old app to allow you to compare: https://emby.media/community/index.php?/topic/8001-emby-for-roku-channel/ Thanks.

He said the old app did produce sound. One scenario I can imagine that would cause that would be if the item had been transcoding. The old app would have forced stereo in that situation but the new app, if the device was set to DD, would have preserved the DD in the transcode - thus producing no sound for him.
pcdery 1 Posted March 16, 2017 Author Posted March 16, 2017 Hi, just for your info, there is two audio option in the roku express+, AUTO and STEREO. When set to AUTO, there is sound in the OLD APP but not in the NEW APP (for 720P file only). When set to STEREO, there is sound in both apps. Just to understand, the settings are not set to FORCE DD, it is normally set to AUTO. I would have assumed that when set to AUTO, the new app should have forced STEREO if DD is not supported. Thank you.
ebr 15435 Posted March 16, 2017 Posted March 16, 2017 I would have assumed that when set to AUTO, the new app should have forced STEREO if DD is not supported. It will. My suspicion is that the device claimed to support DD with that setting turned on. You could confirm or refute that suspicion by sending a log from the app: Set your device back to Auto Go into the settings and turn on debug options Restart the app Play your item that produces no sound for a few seconds Go directly back to the home screen and click the "Send Log" button on the last row Turn debug options back off Come out here and tell me when you sent the log and the name of your Emby server Thanks!
pcdery 1 Posted March 16, 2017 Author Posted March 16, 2017 Done, time 18h19, my emby server name is "EMBY" Thank you
ebr 15435 Posted March 17, 2017 Posted March 17, 2017 Yes, your device reports that it supports DD (ac3) so we are passing the audio along unadulterated. Supported MKV A-Codecs: lpcm,aac,mp3,mp2,wma,wmav2,wmapro,flac,alac,ac3
pcdery 1 Posted March 17, 2017 Author Posted March 17, 2017 Ok, so if I understand, my device claims it supports DD, but in fact, not really. I think it requires an AVR capable of decoding DD+ signal, am I right? But I still don't understand why the old app produces sound and not the new one. Sorry if I look a bit silly, my knowledge in this filed are limited . I just want to understand and help you improve your app.

gold1 3 Posted May 30, 2017 Posted May 30, 2017 I have the same issue with no sound, but my receiver is DD and DTS capable. I'm using a roku stick connected directly into one of the receiver's HDMI inputs. Unfortunately, I'm finding that a lot of files are running into this issue. I uploaded logs just now.

Can you please post the media info for the item in question? It looks like maybe it was coming out of Google Drive...?
gold1 3 Posted May 30, 2017 Posted May 30, 2017 I do sync to my google drive, but this was coming off of a drive connected directly to my server. Below are the stats from Emby. Again, this has happened with frequency on the new app. Thanks for all of your work.
