It is possible the audio codec of the video you're playing isn't supported by the projector, even though the file extension of the video appears valid.

Please follow the steps below to check whether the audio codec is supported.

1. Go to here to download and install the tool “MediaInfo”

2. Run “MediaInfo” and click “File”

3. Click “Open” and select “File” to open the video you would like to check.

4. Check that the audio codec (highlighted in red) is listed in the table below.
If it is not, that audio codec is not supported.

GS50 Codec
Item	File Extension	Codec	Description
Video	MPEG program stream (.mpg, .mpeg) MPEG transport stream (.ts) AVI (.avi) MKV (.mkv) MP4(.mp4, .mov)	MPEG1/2 MPEG4 H.263 H.265 AVC	Max. 1920 x 1080 @ 30fps
Audio	WAV (.wav) MP3 (.mp3) MP4 (.m4a) AAC (.aac) FLAC (.flac)	MPEG1/2 L1, L2, L3 AAC-LC LPCM FLAC
