i am playing a mkv movie on KMPlayer when i switch to another audio stream no sound is being played and i am sure that there is nothing wrong with the second audio stream of the movie.
i tried to uncheck AC3 and DTS under Internal Audio decoder in preference but it did not work. i also tried to change matroska splitter to gabset MKV splitter .that did not work either.
what should i do?
For me the fix was (right click on Kmplayer) "Main Controls" -> "Audio" -> "Audio Renderer" and set it to "Default Device". I had headphones selected as the device to be used and it only played audio for the first instance and the rest had no sound, but when I set 'Audio Renderer' to 'default device' I had audio for multiple instances again.
I had similar problem and fixed it by adding K-Lite code packs all LAV decoders to KMPlayer custom filter manager (using kmplayer prefences -> custom filter manager -> add registered filter) and then switching from KMP Copy Transform Stream Switcher to Gabests Stream Switcher (prefences -> Multi-Audio Streams).
KMPlayer plays other audio files after its next run. (Restart KMPlayer.)
Options > Playback > Output > Audio Renderer > 1: system default
It worked for me.
The issue could be outdated audio drivers. I suggest you download the latest ones from the manufacturers website.
