Hi,

To minimize noise generated from fans of my desktop HTPC, I am planning to buy a laptop to replace it. However, I am not sure whether common laptops with the following GPUs can bitstream HD audio, such dts-hd, true-hd, to AV receivers via HDMI, or in general, recent laptops are able to bitstream? Thx.

intel: hd2500, hd4000
nvidia: gt640m
ati: hd7670m

Yes to all.

Why not just remove some of the HTPC fans? You could probably get by with just the power supply fan and a quiet CPU fan on low speed.

You do know that a laptop could even be louder? It has smaller (which means louder) fans that can kick in and spoil your plan.

Those can but you need the right settings. You'd be better off with a small HTPC unless you need to use the laptop for other purposes.

Laptops can be noisy too. I was using a laptop as a htpc and sometimes during the movie you can hear the fan spin up and down. The laptop was replaced by an i3 Intel NUC and that thing works great and silent. It uses a hd4000 which can bitstream HD audio.

XBMC Decodes both Dolby TruHD and DTSMA. If your Graphics card is not capable of BitStreaming HD Audio, then it will play the DTS Core and Downmix DDTHD to Dolby Digital.

XBMC can't decode DTS-HD MA/HRA, it decodes DTS core only (discussed in this thread).

I don't bother decoding on my HTPC. I bitstream and let my AVR handle it as it is the device in my system specifically designed to decode HD Audio to LPCM and pass it to the speakers with it's superior DAC.

Sammy2, how do you set your laptop to allow bitstreaming to your home theater system? I'm using Windows 8.1 64bit and my laptop is connected via HDMI to my home theater system. I've tried every which way and can only get 2 channel audio. Now I'm convinced I need to buy an external sound card and still, I won't be able to get DTS-HD or Dolby True HD.

Does your laptop support bit streaming of HD audio?
