Hello Everyone !!!!

Im new here and wanted to start by asking if motherboards that have a HDMI port inbuilt will output 5.1 channels of dolby or dts sound so that i can hook the HDMI to my Yamaha amplifier ? Ofcourse this is when playing .mkv files with 6 channels of audio embedded in the video file as AC3 or DTS audio.

If required i can post the exact model of motherboard that im planning to buy/use. Also im wondering if this feature must also be supported by the processor.

Thanks in advance.
 
Yes. You simply bitstream the audio track to the amp (assuming the amp supports the audio stream types that you are attempting to pass).
 
Hi, So should i do anything specific for bitstreaming or does it happen by default. And yes the Yamaha amp does support dolby 6 channel and dts. Those are the 2 basic formats almost all amps support.

No

Don't buy an old computer, some older cheap motherboards don't support bitstreaming.

Pretty sure everything on the market does now.

Im actually buying a new motherboard. My existing motherboard is a DG33FB, though its specs say 6 channel discrete audio, id keep my fingers crossed on that.

Im planning on an ASUS motherboard which has onboard HDMI out. I assume then that it should by default bitstream the multichannel audio via the HDMI port ?

My main doubt is as to whether the processor should also support this feature etc. Like for example high speed RAM sometimes needs a processor and motherboard which can take that speed.

Anything on the market today should be fine, even 50 dollar atom boards will do it.
 
All my hdmi devices defaulted to bitstream.

Edit I don't know if any of the older core series stuff defaulted or supported bitstream.
 
Will the ASUS P8H77-M motherboard support audio bitstreaming via its inbuilt HDMI port and dual monitors (as in 1 monitor on my desk and one to my projector) ?

I tried googling on this but couldn't find an answer since the question is a little too specific i guess.

It is the realtek audio chip on the board, that basically controls what audio options you have. FYI I found what chip was on the board from the Asus specs page for that board under the audio section.
 
Thanks a lot for your inputs. So when i play a dolby 5.1 mkv etc the 5.1 channels would go via the HDMI if im understanding right. What about when i play a 2 channel audio mp3 etc. Will those 2 channels also output thru the HDMI port ? And i also wanted to take the regular 3.5mm jack audio to my speaker enabled monitor for everyday normal use (cant have the HT amp on for 10 hrs just to hear dings and program notifications). Will this dual audio connection work ? Or do i have to reroute audi thru HDMI and then back to audio jack on a need-to basis ?

Same way my plan for video is to have HDMI and DSub connected to the PC. The HDMI goes to my PJ. Dsub goes to my Monitor. Planned scheme is to have them on dual monitor setup but with the PJ being used only for night time movie watching. Any further inputs on if my planned scheme will work and if its wrong would be immensely helpful.
 
Hmm sounds like you will need to mess with the default sound device in Windows to do the switching. However you might want to look at audio passthrough, for example I have my htpc setup to HDMI to the receiver and HDMI to the tv, so when amp is on get audio through it but when off I get sound through the tv. Otherwise it will work but need the setting changed to the 3.5mm output.
 
So sound if set on the PC to output thru HDMI will mute the audio on the stereo jack port ?

You'll likely want to disable other audio devices to keep stuff from potentially bouncing around, but this is very simple usually.

I have a gaming laptop that puts out surround sound, up to 7.1, over HDMI to a receiver or TV, I've used it with both. This technology is part of HDMI itself.


Also, you don't need to worry about the Realtek stuff: when streaming across HDMI, your 'sound card' is actually co-located with your GPU, in this case, it's Intel. The Realtek stuff will be used for the dedicated audio outputs, i.e., the analog jacks and any of the discrete digital connections.
 
Actually the HTPC will double as my everyday work PC. So daily daytime use will be with just my LCD monitor and maybe in the night i might watch a movie. So in the night alone i want the projector to run as a dual extended monitor. In windows 7 there is a menu that offers to instantly connect to the projector as Clone Mode, Extended Mode Etc. So that part is pretty easy. The thing is that when i connect like this will sound automatically get transferred to the HDMI in streaming mode and same way when i finish and redo the extended monitor thing the next morning will the audio revert to the PC's 3.5mm audio jack.

Im sorry im so slow to understand this. Kindly bear with me.
