And what sound mode do people mostly use?
Easy way to answer this question. Do you have 5.1.2?
If you do turn it to Bitstreaming and forget about PCM as you can't use Atmos.
The downside to Bitstreaming also is that it has problems with secondary audio like Blu-ray commentary.
Basically, from what I read about it when trying to get my Atmos to work. Bitstreaming sends the compressed audio track to the receiver. The receiver in turn decodes the sound and converts it ECT all in the receiver.
With PCM, the device decodes the sound and sends the receiver either the digital sounds to be converted to analog or sends it the analog.
The advantage to PCM, is that the source can manipulate the sound where it cannot with Bitstreaming. So like on my PC I use Jriver, Jriver can do alot of sound modifactions, however most don't apply when Bitstreaming is on.
For the Apple, I'd set it to Bitstreaming, as it doesn't have any changes to the sound settings?
As far as apple saying that's the better sound mode. I don't think so, if you have a decent Reciever it's going to have much better decoder than that apple.
When you talk about Jriver that starts to change.
All just from my reading over the last little while. I tried it with a few different devices I notice no difference between PCM and BSing, except that my Atmos works, and that my receiver doesn't just "Multi Ch In" and actually tells me the source material (Dolby Surround, DD+, Atmos ECT.)
