Sound over hdmi via the graphics card

[Mr Feesh]

When I go into the sound settings it only detects stereo speakers but my pc is plugged into my Integra amp which has 5.1 surround sound. Any Idea's?

Set the sound card on your graphics card as the default audio device.

If you only need sound for things like vidoes and series, you'll need to use something like VLC media player and set that to output sound over HDMI. Otherwise, Quicksilver's reply is correct and then all sound would play through the TV.

You might have to use a cable to connect the audio out pins from the motherboard to the audio in pins on the graphics card to allow audio over HDMI.

Sound is working, just wondering why it doesn't show as 5.1 in windows settings. Do most 720p movies that you download contain 5.1 surround sound or must it specifically say so.

If your movies are AVIs then they're most likely only stereo sound, unless they are coded to have six separate audio channels. You're more likely to get 5:1 surround with MKVs and MPEG-encoded files that still contain the original audio.

Also it may have something to do with the software you're using to play it and what card you're using. Graphics cards like onboard integrated options and anything from the Geforce 200 and Radeon HD4000 series don't support a number of necessary audio protocols when playing legit high-definition content. Stuff like Dolby HD and DTS-Passthru was only added in a year or two ago and you may find that the software you're using doesn't decode the video and audio properly. Drivers may also play a part and its worth checking that they're up to date.

Its also dependant on your amp and whether Windows detects that it is indeed a 5:1 or 7:1 sound system.

tried playing it in vlc and pot player. They're normally mkv files. Think its a ATI 5450? I would assume that windows should be able to detect the amp as it's a pretty decent amp. Integra DTR 40.2
