Ok Guys........ let me clear the confusion. I am using a PC as the hub for all my Media. Its connected to my Marantz AV 8003. (+MM 8003 + Pioneer KRP 600M + B&W 683, HTM 61, 685 & PVI Sub). I have most of my music in FLAC, MP3 & Wave and I use Winamp to play all my music. I have several HD 720p and 1080p movies (mostly in MKV format). I get stereo output when the movie or music track has a stereo
soundtrack and I get DTS or Dolby Digital bitstream output when the
soundtrack has DTS or DD.
In your case chipshopshippers you need to send HDMI/DVI cable & an optical cable from Mac Mini to the AV receiver. You need to do this because Mac Mini actaually only has a mini DVI output. You will have to get a mini dvi to standard dvi converter jack which is available from apple. Actally you would be better off connecting a DVI to HDMI cable from Mac MINI to AV receiver. In case u want to use a HDMI cable you will have to connect it via another dvi to hdmi converter (too many converters). Once you have connected the DVI/HDMI cable along with the optical cable, go to input setup On your AV receiver and activate the audio thru the optical input in conjunction with the HDMI input for video. Let your Mac Mini automatically detect the optimum resolution for the AV receiver.....AND YOU ARE A GO!!!
Other PC users can send audio and video together thru a single HDMI cable from PC to AV receiver (if your PC has a compatible HDMI output) In most cases if your PC has HDMI, it will invariably output video and sound, else it would simply have a DVI output instead of HDMI.
Now coming to whether your PC will output multichannel sound or stereo thru HDMI or SPDIF output (optical or coaxial digital output). This will entirely depend upon the setup of your machine. In my case I get stereo output when the movie or music track has a stereo
soundtrack and I get DTS or Dolby Digital bitstream output when the
soundtrack has DTS or DD.This has been achieved by using a codec pack called CCCP, which comes with a DirectShow / FFdShow audio and Video codec. You can download the latest version from.............http://www.cccp-project.net/
After installing CCCP, go to settings and keep everything default just making one change.... uncheck AC3 & DTS under the FFDShow Audio Decoders section & tick on AC3 S/PDIF and DTS S/PDIF under the S/PDIF section. Thats it !!!
By enabling AC3 S/PDIF and DTS S/PDIF, FFDShow Audio Controller sends out a Bitstream signal whenever it detects one. Otherwise all other output is in Stereo. CCCP also enable playback of all possible video formats thru Windows Media Player.
I hope this will sort out all your queries.
Cheers!!
