Agreed. Go with HDMI for audio as well. By the way, which PS3 model is it? If PS3 fat, it can't bitstream audio to your receiver. The PS3 will decode HD codecs as well, but that little red icon on your amp will not light up, as it has received already processed sound from the PS3. The light will come on only when your amp does the job. PS3 slim can bitstream audio as well.
