If you are a first-time user of Kodi, or if you are looking for a guide to make the passthrough AC3/DTS audio quality of your movies and streams better, or solve Kodi sound problems, then you've come to the right place.
I just updated my rpi2 to latest kodi 15.1 and kernel 4.1.5-1.
It seems that audio passthrough for AC3 and DTS does not work any more.
Also, if I disable AC3 and DTS, kodi does not decode all audio channels. I can hear the music of the movies, but not the voices (like the center channel is not decoded).
Rolling it back everything works as expected.(from OSMC forums).
Enable passthrough on Audio output setting
The fact that your movies have two tracks audio -- music of the movies and the voice of movies. Music of the movies are decode correctly by Kodi, but the voice of movies not.
Now go to Settings/System/Audio output set the audio output to 2.0 (setting to 5.1 causes lag on sd streams) and enable Enable passthrough and then Dolby digital (AC3) capable Receiver and then Enable Dolby Digital transcoding and then DTS capable Receiver.
Hi people, wondering if anybody can help,I am new to Kodi and when using my laptop connect to the tv, open the video on Kodi (installed on my TV) via USB 2.0, I can hear nothing, I changed audio input to hdmi and still nothing, at bottom passout device shows as error no device found. Is there any other setting or test I can do to get this normal working?
Transcode audio type to the one that Kodi enable encode
To understand how Kodi processes audio you must first have a basic understanding of how audio in the digital domain works.
When analog audio is converted into the digital domain the near universal format used is Pulse Code Modulation (PCM). All manipulation of audio in the digital domain is always done on audio in the PCM format, therefore functions in Kodi such as volume control can only be done on PCM data, therefore if audio is in one of the Encoded Formats Kodi must decode the audio to PCM in order to manipulate it for volume control.
In other word, when enable Dolby digital (AC3) capable Receiver, Kodi will automatically attempt to direct play AC3 audio if the audio in PCM format, but if the video/container are not compatible then you will get no audio at all.
To solve no sound with Kodi issues, you can go to Settings/System/Audio output settings as a reference method. If the encoded formats of your video file is just the one that Kodi can not decode, you have two choice: one, transcode the video/container to the Kodi enable decode one, second, give up.
