Title: DTS audio (again, sorry)
Post by: maxxsid on September 13, 2009, 08:17:59 pm

Hi,
Maybe some kind soul will help me with this..
I have some DTS (wav) files. They play nicely when configured to play via "J River audio engine (using DirectShow filters)" in MC14.
Same files burnt an a CD/DVD just as files also play nicely (of course).
--> However, when burnt as audio-CD/DVD (cda files), they don't play at all (nothing happens and MC places a small "!" next to the track name) when played with "J River audio engine (using DirectShow filters)" option. If I use "J River audio engine (using input plugin)" then they play but produce static instead of music.
Same audio-CD/DVD play nicely in a cheap Philips DVD player.

Any idea on how to fix this?
(some more info:
Zoom Player is not able to play such Cd's either
Media Player Classic _is_ able to play such Cd's)

Thanks!

Well.. Maybe that was a bad idea to make audio-CD's out of dts-wav's to begin with. My mistake.. I just ripped those wav's back to my hard drive storage.

However.. I played around with multichannel ac3/dts/wav and suddenly they stopped playing - static, chopper noise, slow (1/4th normal) playback. All kinds of bad things but no multichannel output.
I even bough an expensive Xonar soundcard hoping it would fix everything - no luck, same story.

It was all bad until I switched from "J River audio engine (using DirectShow filters)" to "J River video engine (using DirectShow filters)" for dts/ac3/wav - now all is fine! (using ac3filter).

I found that if J River audio engine (using DirectShow filters) is used, Filter 'JRiver Audio Renderer' steps in and hijacks the output.
