Passing through audio from a .wav DTS file

[lehphyro]

Hi,

I've searched the forum for answers but I couldn't find any.
I have a .wav music file with 5.1 DTS sound and would like to play it with VLC passing it through to my receiver via SPDIF output.
I can play movies with 5.1 DTS sound easily (the receiver correctly identifies the sound as DTS), but music files are sent as PCM to the receiver.
How can I do this?

Thank you

Just to let you know, I can successfully play DTS music files using foobar2000 and the SPDIF passthrough plugin (http://www.ga.cba.pl/). I just want to know if it is possible with VLC and how to do it.

It seems VLC player simply can't send raw DTS data of music files to SPDIF out. I think you should make this a sticky post so that people will not have to waste time trying.

VLC supports SPDIF pass-through for MP3, A/52 and DTS.

[lehphyro]

Yes it does, but only for movies.

[Rémi Denis-Courmont]

No. you just need to select the SPDIF audio adapter.

[lehphyro]

It is selected, if it wasn't, DTS audio from movies would not be sent to the SPDIF output.

Any news on this? I'm having the same issue on my Mac. Movies work fine but when I switch output to 'Build in (Encoded)', VLC sets the volume to 14549% and crashes both itself and the audio driver. I have to unplug the optical cable for a few minutes.

Well I can play DTS movies thru optical (Man on Fire) on PowerDVD and the DTS
light comes on the receivers. But not when I use VLC from Linux (Ubuntu 9.10)
My conclusion is VLC when DTS audio is selected will convert it or just use
the normal digital output thru the optical port.

In other words, your audio driver is buggy, as VLC cannot possibly cause a driver to crash thanks to memory protection.

This is a generic built-in audio from Apple, what I assume to be a well tested driver. Plus .WAV dts pass through works fine thru Quicktime. It's only VLC that has the issue.
Also, the volume slider jump to 14549% looks more like a VLC, than a driver bug.

[Rémi Denis-Courmont]

I am not interested in arguing. A driver crashing in a protected memory operating system, such as MacOS, can only be caused by a kernel/driver bug or a hardware failure. It's as simple as that. That does not exclude the possibility that both VLC and the driver be buggy.
