DTS/AC3 problem with SPDIF (for DTS WAV works ok))

[ezequiel81]

Hi, I´ve been reading a lot of posts but I still can't solve the problem.

I have installed k-lite codec. I can hear DTS and AC3 music files
using winamp or even bsplayer (5.1 spdif passthrough), but when I reproduce
a VOB (with DTS sound) or an AVI with AC3 I always get stereo PCM output.
I've tried configuring the AC3filter config to use passtrhough but I only hear
the noise of the undecoded signal. After I restart bsplayer, the AC3filter
dissapears and bsplayer starts using another filter (I do the same until bsplayer has no more filters for audio decoding - then I reinstall bsplayer...).

I have an external USB sound card with a spdif output.

Any advise will be appreciated.

Thanks!
