Is there a way to use digital audio decoders while I play music from my pc to my amp?

[maq1919]

I have a yamaha rxv 2065. I'm playing music on an hp pavillion elite with a realtek hd sound card. I have an optical audio cable going from my receiver to my pc. The thing is I want to use decoders such as dolby digital and dts while I play music. My sound card has these options I turn them on but it still only uses decoders like pli music and neo 6. I know it gets a signal because I chang the hz and that shows up on my receiver when I hit info. My receiver can use these decoders I checked. Let me know if you have any ideas.

I assume you mean sending audio from the sound card to the receiver and not the other way around. The options to use DD or DTS on the sound card are to allow the sound card to decode the formats for playback over whatever speakers you have connected to the laptop.

If the receiver will pick PLII or Neo then it is either a) getting a 2 channel analog or digital signal or b) you changed the sampling frequency on the soundcard and the receiver doesn't recognize the signal (although that usually results in no sound whatsoever).

IF the sound card has a setting that allows you to send digital audio out untouched - usually labeled 'passthrough' or 'raw' then you need to enable that setting. If the options for the DD or DTS decoder are on, the sound card is going to decode the format to 2 channel PCM and send it that way. You can verify that is what is happening by checking the format of the signal on the receiver - if it says PCM then the soundcard did the decoding and that is the opposite of what you want.

You're not getting DD or DTS because you're playing music which 99.99 % is 2 channel. The receiver is receiving a stereo signal and is applying DPLII or DTS:Neo.

Dolby Digital and DTS are encoding methods. They're primarily used as a way to encode and store multichannel surround sound, which is then decoded by the receiver.

You're listening to 2-channel sources that aren't in Dolby Digital. You should be, and no doubt are, feeding 2-channel audio to your receiver. Dolby PLII and DTS Neo 6 are processing techniques that turn 2-channel or higher audio into 5 or 6 channel audio.
