DTS on Laptop Speakers?

[Colin_S]

I have a large number of video files on my laptop with only dts audio. Normally this is fine as I stream it through my PS3 which sends the the audio to my a/v reciever to decode. However when I'm not at home I can get no sound from playing the video files when trying to use my built-in laptop speakers. Is there any way to get sound out my laptop speakers without converting the file?

Use a video player that supports DTS (e.g. MPC-HC and VLC) or - if your player is DirectShow based - install a DTS filter like ac3filter or ffdshow.

If you use Ac3Filter v1.63b to decode DTS remember put a Master Gain of -3 dB to avoid the volume bug (not needed for AC3).
No problem with ffdshow.

[Colin_S]

Thanks, i've got ffdshow installed, think it may be my video player just not supporting that. I'll try VLC

Ok installed VLC but just getting hissing

Hmm... curious. Post a MediaInfo text dump of your video.

MPC-HC should handle it, as should ffdshow. You may need to manually enable DTS audio decoding in ffdshow though. I believe DTS decoding is enabled in MPC-HC by default these days.

Probably that's a SPDIF-padded DTS.

[Blue_MiSfit]

Quite possibly.

What unusual files though. I've certainly never had a need to create any! DTSWAVs - sure, but SPDIF padded DTS muxed with a video track in an MKV?!

i know i'm a bit late with this. Could it be i've not manually enabled DTS audio decoding in ffdshow correctly.

[Colin_S]

The file is a result of using MKVtoVOB

[setarip_old]

Is there a reason you haven't, as requested by "Blue_MisFit", posted a Media Info text dump of one of the files with DTS audio (and instead posted one containing stereo PCM?

I think that may be the issue. This is a dts file, however was created from an MKV using MKVtoVOB to allow me to stream it to my PS3. MKVtoVOB must do something with the audio to trick the PS3 into playing it but it is decoded by my a/v reciever as DTS.

[Blue_MiSfit]

Yes, I'd guess the mediainfo dump he posted is the WAV encapsulated DTS.
