If it is 6 channels, that means you should have 5.1 output at this point. Go to the media info tab to see how many channels it actually has in the file. Right click on the video and click properties. You can check the mixing tab to make sure 5.1 is not being down-mixed (just turn off mixing). I've never used the 'DTS-HD framing for all DTS' option before. Then use the LAV audio settings to turn on (check mark) the bitstreaming for the audio encoding types your receiver will support. Browse through them all but all you should need to change are the main page speaker settings (choose 5.1 or 7.1 as is appropriate), then set the LAV video settings to use DXVA2 native to use your video card hardware decode. Before doing anything else, make sure the CCCP settings are set correctly. If you go that route, just make sure the machine is clean, reboot and install CCCP. It comes with MPC-HC so that makes things easy too. I like CCCP mostly because the default settings are almost always good. I prefer MPC-HC because it is updated often and works well for almost everything. Then make a choice of using VLC (which has built in codecs but I find a bit frustrating for some things) or MPC-HC which uses whatever codecs the machine has installed. I would uninstall all media codec packs and any extra codec software you can find from the machine. My soundblaster live from like 2002 could do that.įirst step is to check the source media. I would be seriously surprised if the sound card can't do it. The player software and codec in use just needs to pass it directly to the HDMI or SPDIF out and the receiver will decode and play it. Because DD is a codec that uses lossy compression, there is a slight sound quality penalty compared to outputting each channel over it's own analog output.The general idea is that encoding is not needed if the media being played already has the audio encoded that way. (for creative cards you actually have to set the default sound device to Speakers in stead of SPDIF). If you have both of those (and it sounds like you might not), then you have to play with the settings a bit to get it working right. To get these to work you need to have a sound card capable of it, and that has the licensing that allows it. Then the signal can be sent over spdif to your receiver where it treats it just like it does any DD encoded movie. If your receiver does not have multichannel analog inputs, or your onboard sound only has stereo analog outputs (rare for a desktop), that's when you need DDL.ĭDL takes the discrete channels coming from the games and encodes them into the Dolby Digital format on the fly. A complete list of independent stereo source. A SP/DIF optical audio devices and you have cant get 5. HD Audio after upgrading to use digital live. When you set them to surround sound mode the game outputs multiple discrete channels that are really designed to be output over the multichannel analog outputs from your sound card (and this is really the best way to go in terms of sound quality). I also have a Vizio 5.1 sound bar connecting to my dell laptop over HDMI cable. Just pick whichever of your receiver's surround modes sound the best. You can play it over analog or digital, but the only way your are going to get it to come out of surround speakers is pro-logic or something like that to create artificial surround. Music is recorded in 2 channel stereo 90% of the time. Play your movie, your reciever's DD light should turn on and everything should be working. (someone back me up here)Ĥ) For MKV files with DD tracks, I prefer Media Player Classic- Home Cinema (MPC-HC), here's how to set it up:ġ) Open MPC-HC and right click the player window and select options.Ģ) Under playback select Output and set your Audio Renderer to System Default or SPDIF (useful if you want to use analog for everything else).ģ)Click Internal Filters on the left and make sure AC3 and DTS are checked.Ĥ) Under Transform filters double click the bold AC3 and DTS.ĥ) Under decoder settings change the default from decode to speakers to SPDIF (ie passthrough) If you want to do this on your computer all you need to do is set your pc to pass the DD or DTS signal through the SPDIF connection without touching it.ġ) Go to playback devices control panel and set your SPDIF as the default device.Ģ) Select it and click properties, then under supported formats make sure DD and DTS are selected.ģ) Make sure your movie file actually has a DD soundtrack (you can use MediaInfo for this, look for 6 channel AC3)Ĥ) For DVDs, Win Media Player is pretty simple is should just work automatically. So if you want to watch a movie in dolby digital is needs to have a DD track in the movie file or DVD. They key here is that they are all pre-encoded. First off, I think you have some confusion about Dolby Digital and DDL.ĭolby Digital (aka AC3) and DTS are multichannel encoding formats used mostly in movies.
