Just out of curiosity. What audio settings in the streaming device are you using? Have you tried different modes, down mixing the signal from 5.1 to Stereo, using PCM (24/16Bit), Dolby (yes/no), automatic loudness limiting or something like that? Does this problem appear independent of these settings? Have you tried a different streaming device for comparison?
