There are several ways to get the multichannel audio signals out of the PC.
| Ouput Signal | PC Output Interface | PC to External Connection (Adapter, Cable) |
|---|---|---|
| Analog | Six 3.5mm Mono Jacks | Mono Speaker Cable |
| Three 3.5mm Stereo Jacks | Stereo Speaker Cable | |
| Six RCA Jacks | Mono RCA Cable | |
| Digital | SPDIF (Optical Toslink) | Optical Cable |
| SPDIF (Coaxial RCA) | Digital Coaxial Cable | |
| SPDIF Motherboard Header | "Header to RCA" Adapter (Link1) (Link2) or SPDIF bracket, Digital Coaxial Cable | |
| HDMI | HDMI Cable | |
| Analog-Digital Combo | 3.5mm-Optical Combo | "3.5mm to Mini Toslink" Adapter (Link), Optical Cable |
| 3.5mm-Coaxial Combo | "3.5mm to RCA" Apadter (Link), Digital Coaxial Cable |
| Ouput Signal | PC Output Interface | Type of Signal Allowed |
|---|---|---|
| Analog | Six 3.5mm Mono Jacks | Uncompressed PCM, MLP |
| Three 3.5mm Stereo Jacks | Uncompressed PCM, MLP, etc | |
| Six RCA Jacks | Uncompressed PCM, MLP, etc | |
| Digital | SPDIF (Optical Toslink) | Compressed dts & ac3, Stereo PCM |
| SPDIF (Coaxial RCA) | Compressed dts & ac3, Stereo PCM | |
| SPDIF Motherboard Header | Compressed dts & ac3, Stereo PCM | |
| HDMI | All compressed & uncompressed | |
| Analog-Digital Combo | 3.5mm-Optical Combo | Compressed dts & ac3, Stereo PCM |
| 3.5mm-Coaxial Combo | Compressed dts & ac3, Stereo PCM |
And then again there are two ways to get the actual audio thorugh the speakers
a) For analog multichannel audio - Use a 5.1 or 7.1 PC speaker system or Home Theater Receiver that has multichannel analog input, hooked up directly to the six 3.5mm mono jacks or six RCA jacks or three 3.5mm stereo jacks
b) For digital multichannel audio - Use a Home Theater Receiver capable of decoding multichannel digital audio hooked up to one of the digital output interfaces mentioned above.
Rules
1) Play the media in Foobar or Media Player Classic or VLC media player or Windows Media Player or PowerDVD
2) Set bit depth in these players as well as your soundcard controller to 24bit or less
3) Set sampling rate to 44.1kHz
You HAVE TO turn up the volume to maximum everywhere in your computer (player, sound controller, etc). You can control the volume ONLY through your HT receiver.
Soundcard Controller Settings
In my case its Sound Blaster Live 24bit
and
Windows XP Audio Controller Settings
1) Turn up the volume of Playback and Wave to maximum
and the use the following setting under Playback->Advanced
Players and their settings
Using Foobar
1) Install Foobar either using the following settings
or
2) Install Foobar SPDIF passthrough plugin from Here
3) Turn up the volume to maximum (i.e. 0dB)
4) Deselect all DSPs as shown below
or
5) Use the following settings under Preferences->Playback (Optional)
and under Preferences->Playback->Output (Optional)
6) Use the following settings under Preferences->Playback->SPDIF
Using Media Player Classic
1) Use the following settings in View->Options->Playback->Output
2) Turn up the volume to maximum
3) Use the following settings in View->Options->Internal Filters->DTS or AC3
Using VLC media player
1) Use the following settings in Settings->Preferences->Audio
2) Use the following settings in Settings->Preferences->Audio->Output modules
Using Windows Media Player (For playing wma pro)
1) Use the following settings in Tools->Options->Devices->Speakers->Properties
You should now have 5.1 channel DTS/DD audio through your 5.1 HT speaker system.
Notes-------------------------
When using KS output, the kmixer is bypassed, so you can mute WAVEout (and everything else except Main Volume) in the mixer. This way there's no other sound that'll find a way to your speakers
* Use S/PDIF when available: ON
* (Advanced options) Audio output module: ALSA audio output
* ALSA Device Name: hw:0,1
