It is possible that the audio format for the file you are trying to share is not supported by RushTera. It is likely that your original file used PCM audio, which is not a supported streaming audio format. To ensure that your audio streams correctly we suggest encoding using the following audio settings:
FORMAT: AAC
CHANNELS: Stereo (L, R)
SAMPLE RATE: 48.000 kHz
BIT RATE: 192kbps (if bandwidth is an issue, a lower bit rate like 128 kbps may be used)
