No sound on iPlayer Solved?

Was having trouble with no sound on iPlayer with DD5.1 optical out to a Sony Davs Z260.I have found that if I disable

AAC Capable Receiver in audio settings on the Live the sound works as it should without altering any settings on the Live to stereo only.Is this a bug?

The problem only happens with the BBC player?

Yes only with iPlayer
