Thank you, I finally have everything working great. I bought another HDMI cable and I have everything connected through HDMI: Laptop > HT Receiver > LCD TV.
Besides, I'm able to get 5.1 audio with DTS, AC3, AAC, everything.
I have only one extra question:
To get AAC 6 channels I have to set PotPlayer/MPC to decode and send 6 PCM channels to the receiver, right? I can do this with DTS and AC3 audio too (the receiver displays PCM instead of DTS or Dolby Digital).
But if I set to passthrough DTS and Dolby Digital directly (receiver shows DTS or Dolby Digital) I don't get nice volume, I have to put the receiver to MAX (40) to hear the same volume with PCM in 25-30.
Also, the voices are too quiet. Because the Loudness Equalization is not being applied.
So, what are the actual advantages of passing through DTS/DD to the receiver instead of decoding them in the computer?
Why am I getting less volume with it?
