PS3 Audio Settings: PCM or Bitstream?

by josimar304 / August 12, 2010 4:47 AM PDT

Hey guys, so I have my PS3 plugged to my AV receiver through HDMI, and my AV receiver through HDMI out to my tv. I currently have the audio setting on my PS3 to output Linear PCM, as well as my AV receiver, but I get mixed up answers on which one is better to use. I simply watch Blu-rays and play games...Thanks in advance!

depends on your receiver

Does your receiver have onboard decoding of DTS-MA and TrueHD sound modes? If so, you can set it to bitstream. If not, only use Linear PCM or else you will not be able to utilize the HD sound formats.

I believe so...

My receiver is a Sony HT-SS2300. Many have told me that PCM provides lossless audio, but I am not an audio expert, so that's why I set it to Linear PCM, but yet again, I do know that not all blu rays are encoded in Linear PCM, and I also know that not all are for 7.1 surround sound, which is what led me to settle for a 5.1 receiver. So to answer your question, I think my receiver does decode the HD sound formats. Double check for me if you can, please.

A quick look at the spec sheet for your receiver shows that it does not have onboard DTS-MA and TrueHD sound decoding. That means you should leave your PS3 set to "Linear PCM". Your receiver can receive 5.1 LPCM via HDMI, which means your PS3 will take a Blu-ray DTS-MA/TrueHD sound track, convert it to LPCM, and send it to your receiver. That way you will still get the high bitrate of the HD sound formats.

Oh and another tip for PS3 audio settings, turn "Dynamic Range Control" off. When it is on, it tends to diminish the quality of sound.

LPCM it is...

I realized my receiver didn't have any HD sound decoding, after I replied, but thanks for the explanation...I further understand a bit more about Audio Decoding and stuff...
