I noticed that when using SCART the left channel volume is inaudible. If I plug headphones in AV1 out and max out the headphone volume then I can only hear the left channel okay but it’s still lot quieter than the right channel. This problem ONLY persists with the SCART connection. I have tried plugging the consoles straight to the TV and then the audio works just fine.
Other interesting detail is that if I set the Pre-gain past 5dB, the audio gets garbled and cuts out almost completely.
– I have multimetered the SCART connector on the board and it seems to be fine
– tried different SCART cables and HDMI cables
– played with the volume switch on the board
– tried older firmware (0.90->0.89)
Any tips or suggestions?
