Bitstream

[katyayan]

I bought JBL cinesystem500si recently. I am still trying to understand all the functions.
Should i let my AVR do the audio decoding, in this case AVR shows 'Dolby digital etc' on display or should i use my video player(i use pot player) and send multi channel PCM to my AVR, in this case AVR shows '3/2/.1 48 PCM' on display.
Which is better and why?
Thanks in advance.

PCM is uncompressed and it should be better. But it all depends on your ear and what you hear. Just try both and see what feels comfortable. Dolby D and DTS are compressed formats.

Normally you would want to send audio from source as it is (bitstream) to your AVR and let your AVR take care of audio processing or DD/DTS/TrueHD/DTS-HD (etc.) decoding.
However, if your media file has uncompressed audio then you would only see PCM.

DD/DTS are lossy audio and TrueHD/DTS-HD are lossless. Specially for TrueHD/DTS-HD, you need to use bitstream it to AVR to enjoy it to fullest.

Hope it helps.

I have one DTS audio cd 5.1 in lable. DVD Plays with no audio. Tried in laptop, only noise no audio. Setup is DVD to TV and then optical out to DAC. TV I set to PCM.
