Invalid DTS sound for SPDIF output

[Megavoltus]

I try to set DTS Speakers to SPDIF (for playing DTS-WAV files with hardware DTS decoder). Result - sound is bad (slowly and with random breaks).

(menu Options->Preferences->Filter control->Decoder Usage->Internal Audio Decoder->DTS Speakers).

Other players playing DTS normaly.

Please fix this bug in KMPlayer.

My config:
KMPlayer Version: 2.9.3.1214
SoundCard: Creative X-Fi Xtreme Gamer (with unlocked hardware Dolby/DTS decoders)
CPU: Core 2 Duo E6750 (rev G0)
MB: ASUS P5K
RAM: 2048 MB


P.S.: Thanks for excelent player :)

Are you sure it is a dtswav, not dts?

AFAIK, it is imposible to do passthru with dtswav.

How did you do and what is the player?

Can you make a small sample to verify?

Extension of file is DTS. Internal structure of file is very similar to WAV format, but players, who not support DTS-WAV files, playing this as modem noise.

My soundcard Creative X-Fi Xtreme Gamer contains hardware Dolby Digital and DTS decoders. But this decoders in this model locked by Creative (in drivers). I replace some files in drivers from old similar models, so decoders now unlocked and I can see Dolby Digital & DTS pages in driver settings. When SPDIF selected as output device, decoders works perfectly.

See details on [Only registered and activated users can see links] (sorry, in russian). You can use X-Fi_DD&DTS_Unlocker.rar patch to unlock Dolby & DTS decoders on X-Fi soundcards. [Only registered and activated users can see links]

But KMPlayer with SPDIF output (to use hardware DTS decoder) playing DTS files with defects... :(

My steps:
1. Start KMPlayer
2. Open menu, select Options->Preferences...
3. Open Filter Control->Decoder Usage->Internal Audio Decoder page
4. Select "SPDIF" for DTS Speakers
5. Click Close button
6. Open *.DTS file

KMPlayer playing it. But the music has some artifacts. :(

1. Music is very slow speed
2. Sound has some unpleasant pulses

Sound is good when DTS Speakers selected to "2/0 : stereo" (software DTS decoder).


Can you make a small sample to verify?

OK, see attachment with 3 sec of result sound example recorded with 48KHz 16 bit stereo...

Ok, It is a dtswav file.

That's right. It's actually dts wrapped in wav container. So the extension should be wav. KMP can correctly detect it.

When SPDIF selected as output device, decoders works perfectly.
You ate my question. :) What is the player? Which decoder do the passthru? Is it a directshow compatible player? Maybe not. That is, it may be impossible to do the job with any other directshow applications as well as The KMPlayer.

In directshow appls, so called a pure DTS (mainly in the part of video container) may be only possible to do passthru. KMP is a directshow appl too.
