[SOLVED] Problems playing DVD files.

[J7N]

If the sound were not demultiplexed corectly, the splitter should be changed. Putting a filter (dtsac3source) where it does not belong to remedy a given single problem will only produce problems in the future.

In this case I would look what data does AC3Filter receive, if its sound level meters move reasonably in sync with the signal, what is the selected output format (bitdepth, num of channels - as Tizio said) is spdif passthrough is active. The defaults used to be very conservative last time I checked: Stereo, 16-bits, but that might have changed. Next I would check what does the Sound Renderer show (the bitdepth, channels, and ACM format will be reflected there).
