Guest Posted March 24, 2021 Share Posted March 24, 2021 Hello, unfortunately I do not have any sound with some files when viewing them over WAN on my FireTV device. The files all have AC3 audio and they all play fine on: - browser (WAN and LAN) - FireTV (same device but different app) - emby for kodi - VLC What can I do to have audio with these files? The next time I have access to this FireTV I will open the SFN window and get logs and further information. Link to comment Share on other sites More sharing options...
rbjtech 4276 Posted March 24, 2021 Share Posted March 24, 2021 Which Gen of FireTV stick ? I have noticed and reported that the Gen2 FireTV stick is not recognising AC3, so it is converting to AAC (which plays, but it should not need to do this). This could be related. Are any ffmpeg logs generated when you play the items with the failed Audio ? Link to comment Share on other sites More sharing options...
ebr 14918 Posted March 24, 2021 Share Posted March 24, 2021 Hi. How have you set the audio settings in the Fire TV settings themselves? It is possible on these devices to set those in such a way that you will not get any audio if you don't have the proper equipment. Link to comment Share on other sites More sharing options...

Are any ffmpeg logs generated when you play the items with the failed Audio ? I am using a Gen 1 Stick. Yes, there are logs - I attached the one from my last test. Just a few seconds to test some settings I changed in the client and the FireTV Stick - but no sound. 6 hours ago, ebr said: Hi.

I changed almost every setting but reverted them back to standard as none of them changed anything. Audio plays fine with the same video using a different client on the same FireTV stick. ffmpeg-remux-6934d24b-5021-49be-a65b-731e966953df_1.txt Link to comment Share on other sites More sharing options...
ebr 14918 Posted March 24, 2021 Share Posted March 24, 2021 Hi. The server is converting to 5.1 AAC - which isn't going to work. In the app playback settings, there is an "Audio" option. Try setting that to "Mix down to stereo". Link to comment Share on other sites More sharing options...

ebr 14918 Posted March 24, 2021 Share Posted March 24, 2021 No, you don't have to restart the app but it sounds like maybe restarting the device might be something to try. What is all the equipment involved and how is it connected? Link to comment Share on other sites More sharing options...
Guest Posted March 24, 2021 Share Posted March 24, 2021 The device is restarted every day (power on/off cycle). But I will change the setting and directly afterwards restart the device. There's only the FireTV and a TV - nothing more. The FireTV is directly attached to the TV via HDMI. LAN/WAN via WiFi Link to comment Share on other sites More sharing options...

It's not desirable as AC3 should work directly - but there is an issue with the FireTV recognising AC3 - Same issue on the Gen2. https://developer.amazon.com/docs/fire-tv/device-specifications-fire-tv-stick.html?v=ftvstickgen1 I note the first Audio track is German - followed by an English track. In Audio/Subtitle settings on the client, there is a 'Preferred Audio Language' and a 'Play default Audio Track regardless of Language' - have you set these options ?

I am not sure about the first one but I've set the latter option. It doesn't matter which audio stream is selected - there's no sound with either of them.

Luke 37090 Posted March 29, 2021 Share Posted March 29, 2021 @Razorblade are you still having an issue with this? Have you checked the fire tv audio settings? Link to comment Share on other sites More sharing options...
Guest Posted March 29, 2021 Share Posted March 29, 2021 @Luke Yes, I do but I did not have the opportunity to check the audio settings, yet. I'll do so on Wednesday evening and report back. I will check "Mix down to stereo" and both options 'Preferred Audio Language' and a 'Play default Audio Track regardless of Language' and do a restart of the stick. Do you need any additional log files? Link to comment Share on other sites More sharing options...

Guest Posted April 1, 2021 Share Posted April 1, 2021 Hi, sorry, I first had to check and get all the requested information. Audio settings in the Stick are set as follows: Audio Output set to "Auto" Changing to "Downmix" did not change anything Dolby Digital Output set to DD Plus Auto Opening the SFN window tells me that it's transcoding because of unsupported audio format Player: exoplayer Method: Direct Stream Type: HLS Video Codec: H264 (direct) Audio Codec: AAC Channels: 5.1 Media Information: Container: mkv Video Codec: H264 Audio Codec: DOLBY Channels: 5.1 Do you need any further information?

Guest Posted April 2, 2021 Share Posted April 2, 2021 13 hours ago, ebr said: Are you positive? Yes, I absolutely am. I did change this multiple times and checked multiple files with that setting.

This is also what I thought. Link to comment Share on other sites More sharing options...
ebr 14918 Posted April 2, 2021 Share Posted April 2, 2021 Can you play something for a few seconds with that option enabled and then send a log from the app? Link to comment Share on other sites More sharing options...

Guest Posted April 10, 2021 Share Posted April 10, 2021 (edited) @Luke @ebr Hi, I just sent/uploaded the debug logfiles. I played an episode of "The 100", the logged in user was embyuser and the time was around 10:55 UTC-5 Please let me know whether you need further information or log files. Edit: Oh, and of course, I enabled the "Downmix" option Edited April 10, 2021 by Razorblade Link to comment Share on other sites More sharing options...
Solution ebr 14918 Posted April 10, 2021 Solution Share Posted April 10, 2021 Okay, the system is reporting no support for Dolby and that is causing it to convert on the server in that version. The next version of the app will behave differently and decode it locally. There is also some sort of network issue as there was a timeout at one point during your playback which cause another fallback to transcoding.

Guest Posted April 12, 2021 Share Posted April 12, 2021 Hi, Thank you very much for looking into this. Yes, I already noticed some networking issues and I am trying to find out why. Do you know when the new version will be available? Link to comment Share on other sites More sharing options...
