So im not exactly an audiophile but I got a receiver for about 100usd.(yamaha rxv463) Was wondering if my pc can decode hd audio so that I can transmit it to the receiver via the gpu. Im yet to buy a gpu so can anyone recommend a good one for this task, no radeon products please.

What is "HD Audio"? And why do you need a GPU to transmit it?

Imagination is more important than knowledge.

The receiver cannot decode these type of audio that's why I am building a htpc. hd audio can only be transmitted via a hdmi cable to these receiver that's another reason I need a gpu with such capabilities or is there a work around I don't know about.

Ummm... Computer video cards don't output audio... Look into a sound card with 5.1 out. Then, just wire those outputs into the corresponding inputs of the receiver.

What your attempting to do will not work unless you have a reciever that can decode HD audio formats like DTS MA, Dolby True HD, and Uncompressed PCM. All your HD card will do is output that HD bitstream via HDMI. There is currently no PC hardware available that decodes HD audio the way you want done. Standard 5.1/ 7.1 audio is all they can decode right now. HD Audio is exclusive only through HDMI, with the use of a reciever or processor that can decode the data.

In regards to GPU ( Graphics processing unit ), it's not exactly a proven technology. It still a bit buggy. You really have to know what your doing when you are using it, other wise your going to have driver failures while decoding. A good example is green video while decoding. Also, you have to worry about ram usage because if you cach the whole movie, the second watch will have problems because your ram will be full.

I suggest you sell your current receiver and buy one that can decode HD audio, and buy an affordable BD player. You can get one for 70$ at walmart. Of course this is just my own opinion.

What if I was to just purchase a BD player that can decode lossless audio. I have just seen a DENON AVR3806 7.1 receiver and it does look quite affordable. Most receivers that can produce the kind of power similar to it cost about 1200usd but I am getting this for 300usd

You will need a receiver with a 5.1/ 7.1 multichannel analog input to be able to do that. You would also need 3 to 4 pairs of RCA audio cables to connect the player to the receiver.

You may need to change some settings on the player to make sure it is decoding the lossless track instead of a lossy one. Sometimes, secondary audio processing will lead to lossy decoding.

You may also need to turn off the HDMI audio output from the receiver to the TV. Sometimes the HDMI handshake with the TV will tell the player to downmix to stereo.

always wanted to ask is there really a difference between DTS 5.1 and DTS HD MA in what you hear?

Yes, there is a difference. Some sound really great and others while they sound good, they don't have much surround. Core DTS ( which is the theater standard ) has a bit rate of 1.5 mbps, and DTS HD Master audio supports variable bit rates up to 24mbps. The DTS your probably use to is from DVD, and it only has a bit rate of 780kps. Core DTS is twice that.

You also need to be aware that just because it says DTS HD master, doesn't mean it's going to sound like a brand new movie. Alot of times the master that the studio decided to use didn't sound all that good to begin with. For example alot of the older movies ( from the 80's and 90's for example ) just making their way do bluray will not sound like a brand new release of a movie just a few months ago. I have a quite a few older movies on bluray, and most of them sound dated. Oliver Stones "Platoon" bluray is a really great example of really dated soundtrack, and DTS HD master audio didn't really help it that much.

Hope all that makes sense.

If the box says that the system is capable of playing DTS HD Master audio, then your good to go, but make sure the HTIB is capable of DTS HD Master Audio before you buy it.
