No they are different. A movie will be a container (AVI, MKV etc) and when you play the file it will determine that the audio contains DTS and it will get passed through to your amp. With a WAV file it does not know what is in it (in fact WAV files only store uncompressed audio). Having DTS audio inside a WAV file is a bit of a trick and only works if the audio gets to your amp untouched. When you playback a WAV file the content is treated as uncompressed audio and passed to your amp as such, your amp then realises it is actually a DTS signal and plays it back.I dont understand this. Isnt it the same with DTS movies then? Those are correctly passed through to my Amp unchanged. Why isnt it the same with music files? The Hardware setup in Windows regarding my sound output is the same.
You are still using a soundcard, just the one inbuitl into your graphics cardI dont even use a Soundcard, i use the HDMI out of my Graphics Card directly to my SV-Receiver.
PureAudio bypasses many issues like this within Windows. The actual hardware / driver side is not changed by PureAudio. As LordMerlin says changing the output sampling rate may solve your issues for these files but as soon as you play a track at a different sample rate (AC3 files tend to be at 48Khz) you will get the same issue.Plus i still dont understand why it doesnt work with pureaudio. I thought it was used to bypass the exact problem u described about my soundcard.
PureAudio and ASIO can allow you to bypass the middle section of this chain but if the driver is messing around with the audio then DTS in WAV files will never work (changing the sample rate is often enough to change this but is driver/hardware dependant)a playback chain (player software => kmixer/audio service => driver) can be tested for whether or not audio processing takes place: if the chain is bitperfect, the receiver decodes the DTS, and if the chain isn't, the receiver plays white noise.
These need to be DTS files not WAV files. I think you can probably just change the extension to DTS, these will then no longer be treated as WAV files and you relying on an unchanged stream being sent to the amp but the files will be identified as DTS and sent to your amp as they are in films.Can you throw me a link or explain a bit deeper what to do with wmplayer/ac3file combo pls.
I managed to have the wmplayer plugin handle my wav/dts files but its still whitenoise.
If it works with winamp and AC3Filter then it should work in MP using WMP player and AC3File. Open up the DTS file in WMP and see if that works. If it does then chances are you are missing DTS as an extension for WMP player or it is also used by PureAudio or main MP player.What works is renaming the Files to .dts and play them with Winamp+AC3Filter plugin, it even works bitperfect then with my Receiver showing DTS. Which i dont understand cause its the same Driver(AC3Filter) and the Hardware is unchanged.
WinAmp is fixed in 1.2 but that should be a last resort as this will work.... (just take a little persuasion)Problem is i cant use Winamp as an external player cause it opens, but only shows a Drive Letter and wont play the File(s).
Neither with PureAudio+ASIO4ALL nor with WMP+ac3file/filter (not even with WMP alone outside MP) do i get anything else but whitenoise
