In case of problems with multi-channel sound reproduction while using Elmedia Player, pay attention primarily to these 2 things:
1. Is the audio equipment that’s connected to the Mac configured correctly? The audio equipment can be configured, using a system utility called “Audio MIDI Setup”. You can read more here.
From the main menu, go either to Elmedia Player -> Preferences -> Audio or to Audio-> Audio Device / Audio Channels, and select the required audio device and the proper number of playback channels.
If the playback issue is still unresolved, you can try the following steps:
1. Go to System Preferences -> Sound -> Output, and select your Audio Device as the device for sound output.
2. Access the Audio Device menu in one of these ways:
- Elmedia Player -> Settings -> Audio -> Audio device
- Audio -> Audio device
If the problem occurs when playing surround audio that’s encoded in AC3 (Dolby Digital) or DTS (Digital Theater System), it can be solved by enabling / disabling “Passthrough for hardware decoders: Enable for AC3 or DTS” in the player settings. Not all audio devices can decode AC3 and DTS.
