djdyna Posted June 23, 2011 Posted June 23, 2011 (edited) As the topic title states how do I get 5.1 audio from the motherboard to my AMP, i know my HD5770 delivers audio direct though HDMI, but i have no way to get the 5.1 form that to my AMP, so i obviously need a cable from the motherboard to my amplifier. Please help, thanx.

bigball1 Posted June 23, 2011 Posted June 23, 2011 What model of AMP do you have? Share this post Link to post Share on other sites More sharing options...
djdyna Posted June 23, 2011 Posted June 23, 2011 What model of AMP do you have? It's for my upscaling DVD system which takes in x2 Optical ins. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted June 23, 2011 Posted June 23, 2011 A picture or diagram of the available ports on your amp would be a big help Very few if any amps have six discrete mini-jack inputs so your solution will have to include converter cables from mini-jack to rca (assuming your amp has rca inputs). Your motherboard manual should have instructions for pairing up the right/left/center/sub outputs from the onboard sound so they can be ported (two channel analog only) over to your amp. Then you'll have to hope that your amp can decode or fake 5.1 sound. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted June 23, 2011 Posted June 23, 2011 Disregard my previous post. After your latest update I see that you only have two optical inputs on the amp. Guess that completely trashes any ability to get analog mini or rca cables from your onboard sound to the AMP. Quite possible that your only solution will be to add in a sound card that has optical outputs....................... Share this post Link to post Share on other sites More sharing options...
The Smith Posted June 25, 2011 Posted June 25, 2011 Quite possible that your only solution will be to add in a sound card that has optical outputs....................... Either that, or change your motherboard to one that has the optical output directly. This one is the cheapest on Newegg. Share this post Link to post Share on other sites More sharing options...
ir_cow Posted June 25, 2011 Posted June 25, 2011 i think your going to have to get a soundcard with optical Share this post Link to post Share on other sites More sharing options...
xPETEZx Posted June 25, 2011 Posted June 25, 2011 To get true surround to your AMP in this instance, you can either run an optical cable from your motherboard (if it has one), but note that this solution will give you 5.1 ONLY from DVDs and films which are encoded with Dolby Digital & DTS surround. Any other sound with surround channels (such as games) would be converted to 2 channel PCM. To get true surround from your games you will need a Sound card which has a digital encoder on board. Examples of this include the ASUS Xonar cards. These cards are capable of encoding audio into a 5.1 DTS interactive, or Dolby Digital Live stream. Alternatively, depending on how good your AMP is, you could just be happy with 2 channel PCM, which the amp then stimulates to surround. My media PC is connected to my AMP via HDMI. Any film I play with DTS/DD audio will get passed in true 5.1 sound to the amp, however games will only be passed in 2 channel. I dont find this a problem for my media PC, as the AMP is very good at emulating surround. (sure its not as good as true surround, but for casual living room gaming, its perfect!) The last option which may be open to you, is your computer connected to a TV? One of the my friends runs the following setup: HD5770 via HDMI to Samsung TV. Samsung TV via optical to surround sound system. This allows him to avoid having to use an optical cable from the PC to the surround system. It also doubles up to allow all his connected devices on the TV to make use of the surround sound system. (It only has 2 optical in like yours) Works great, but as above, you only get true surround when playing DVDs/films with DTS/DD tracks.

ivangela Posted June 25, 2011 Posted June 25, 2011 I run an HDMI cable to my amp from my PC. Works for me because I use my PC as a HTPC Share this post Link to post Share on other sites More sharing options...
wevsspot Posted June 27, 2011 Posted June 27, 2011 Guys, his board doesn't have HDMI, digital or optical out. His onboard sound is analog only via mini jack. So his only two options are a different motherboard or a soundcard with optical outputs (as his amp only has optical in). Share this post Link to post Share on other sites More sharing options...
sticknstone Posted June 28, 2011 Posted June 28, 2011 MCP73PV MicroATX Motherboard has internal connectors for a rear mounted slot bracket spdif out jacks. Find one bracket with optical out. The motherboard I purchased has the connector, but did not include the bracket in the mobo bundle. Share this post Link to post Share on other sites More sharing options...
