Sancus 1 Posted August 19, 2020 Share Posted August 19, 2020 (edited) I have a lot of 5.1 FLAC music that previously played just fine, using an Nvidia Shield TV Pro 2019 connected via HDMI to a Denon X4500H. On 1.8.24 it looks like it's being forcibly transcoded to stereo. Transcoding log here. That seems to be the cause of the issue. If I uncheck "Allow audio playback that requires transcoding" then Emby does not transcode and the file is played back correctly as multi-channel.

Carlo 4328 Posted August 19, 2020 Share Posted August 19, 2020 Hello @Sancus any chance we could get you to try the latest beta to see if this improves things for you? Link to comment Share on other sites More sharing options...

I did join the beta program on Google Play(It says "* Beta" under the listing now), but haven't been able to get it to update on the Shield yet. Uninstall/reinstall didn't work either, just reinstalled 1.8.24g. Not sure if there was some other step I'm missing. Link to comment Share on other sites More sharing options...

MateyTate 15 Posted August 19, 2020 Share Posted August 19, 2020 I’m too having this issue. Sat down to listen to a bit of Dark Side of the Moon which is FLAC 5.1 and used to work, and today it’s stereo only. I’m not really clear from reading the above thread where the issue lays? Is it the Emby app on my shield, or the Emby server on my Synology? Is there a fix? Link to comment Share on other sites More sharing options...

Quick question... do I remove the installed Emby app first, or does the beta overwrite it... or sit alongside it? I’ve never installed an Emby Beta before?

Sancus 1 Posted August 19, 2020 Author Share Posted August 19, 2020 Sideloading to Android TV is tedious, but I can confirm that beta 1.8.28 resolves this issue, I was able to re-enable transcoding and it's correctly playing 5.1 FLAC files as multi-channel without transcoding now.

Thanks. That fixed it! As always, thanks for the amazing support! On another note, I was getting constant Volley errors and the Home Screen was taking ages to load up. I followed the guide for vacuuming the database (took me a while to get there using SSH on my my Synology) but since running that no more problems at all. It’s so quick like it used to be. I see lots of people with the same volley errors so it’s definitely worth recommending they do that! Edited August 19, 2020 by MateyTate Link to comment Share on other sites More sharing options...

MateyTate 15 Posted August 27, 2020 Share Posted August 27, 2020 (edited) @ebr I spoke too soon, well, kind of. It seems the beta fixes the playback of 5.1 FLAC files, however I have a number of quadrophonic albums in FLAC (i.e a channel layout 2F2R) and the rear channels do not play at all. The web app plays them fine (as does VLC) so I know the files are good, it’s just the Shield app. Not the end of the world, just annoying.

Xorp 47 Posted September 2, 2020 Share Posted September 2, 2020 I see in the changelog for 1.8.28g August 19th production release it says "Fix FLAC playback" but it doesn't appear to be fixed. FLAC still gets detected as "unsupported audio" and transcoded. Link to comment Share on other sites More sharing options...

MateyTate 15 Posted September 4, 2020 Share Posted September 4, 2020 Hi @Luke, unfortunately (for me) that didn't work either. On the Shield, neither Emby app will play the rear channels of these 4.0 quadraphonic FLACS - nor will X-Plore if I try and play it directly from my NAS. The LG Emby app will not play them either, but strangely the Emby web app on my Mac will. I only have 3 or 4 albums in this format so its no big deal (I may even be able to up mix them to 5.1). I'll more than happily send you a 20s clip of one of the files if you wanted to play around with it... I've also attached the media info just in case you can spot something obvious? But to be clear, its the rear channels that will not play. Thanks for the help Link to comment Share on other sites More sharing options...
MateyTate 15 Posted September 4, 2020 Share Posted September 4, 2020 (edited) Quick update. I added a couple of blank channels in Audacity for the centre and LFE and exported as a 6ch FLAC and all is good so I’ll do that for the 30 or so songs I have I’m no expert, but maybe FLAC 4.0 isn’t even a valid channel map?

Luke 36881 Posted September 6, 2020 Share Posted September 6, 2020 It sounds like the native audio player on the device just doesn't support it. Link to comment Share on other sites More sharing options...

I thought Emby for Android used it's own embedded copy of ExoPlayer? So Emby for Android now relies on the OS's media decoders? Kodi's embedded decoders do not have issues with FLAC audio tracks. If audio decoding was moved from an internal decoder to a OS decoder library, maybe it would explain why these FLAC track used to play fine in Emby for Android, as I reported on February 17, 2018 in my link.

Here you go, FLAC 1.0, 2.0, 5.1, 6.1 and 7.1 samples: https://www.sendspace.com/filegroup/ud7pndUOyISE3xFCgqAuWGK45%2BHyEM%2FotYHPOqGyS%2Bc 1.0 and 2.0 get transcoded to AAC and 5.1, 6.1, 7.1 get transcoded to DD 5.1. I swear on my mother's grave that the Emby for Android builds circa 2017 would properly decode all these FLAC arrangements to PCM. Link to comment Share on other sites More sharing options...
