No audio output is normally cased by the wrong audio codec being used or an incorrect setting in BrightAuthor.
- Verify that the video has audio.
- If playing back MPEG1/MPE2 Video, verify that the audio is MPEG-1 Layer II or MPEG-1 Layer III.
- If using AC3 in MPEG2 video, AC3 audio can be passed through over HDMI or SPDIF, but not decoded by the Brightsign. If using Adobe Premiere to encode the video with the SurCode codec for audio, SurCode needs to be in BlueRay mode, not Dolby Digital.
- For H.264 video, AAC audio is decoded, but not AAC Surround. So, if the video is using AAC Surround, you wouldn't hear any audio over HDMI or SPDIF to your display (or over analog output). PCM audio is only supported on XD players.
- For WMV video, WMA audio is not supported: Try converting to MP4 (e.g. using Handbrake or the latest Microsoft Movie Maker).
- In BrightAuthor, under properties for your main zone, verify that the audio output setting is correct. For example, if you're using HDMI for audio, and the audio output is set to analog only, you won't hear any audio.
- If you are using the USB Expander or an HD600/HD2000, verify you are plugged into the correct audio output and you've set your playlist or script to use the corresponding audio output.
- Try re-encoding the video, or using a different application to encode the video.
