Audio Issues

no audio on some channels

• Reason 1:

  • Sometimes this happens when you selected "SPDIF passthrought" in the codec configuration and connect your TV with analog stereo to the HTPC. This means that on channels which broadcast AC3 audio, you wont hear anything from your TV-Speakers, because "SPDIF passthrought" is selected.

• Solution:

  • Either choose "decode to speakers" in the filter configuration, or connect your Dolby Receiver with the SPDIF of your HTPC

• Reason 2:

  • If the TV-Channel where this issue occurs conatains and MPEG1 mono audio channel, then you will have to choose an audio codec which is able to process this audio stream.

• Solution 2 (for Vista users):

  • Choose Microsoft DD decoder as audio codec.
