[QUOTE="jameson_uk, post: 570986, member: 11220"] I believe your soundcard re-samples everything to 48khz which will break DTS in WAV no matter what you do.... The issue here is wav files. MKV files etc will say they contain AC3 or DTS and therefore the signal gets treated as DD/DTS and all the right flags get set etc. With WAV files you simply have a stream and it just so happens that if your amp get this as is it will recognise it is actually a S/PDIF stream containing DD/DTS. For my DTS files I have simply extracted the DTS stream and then stored that as dts file. This then will get treated as an MKV file for video (as long as you have AC3File installed and set the player to directshow). The easiest solution is probably just to re-rip the files to just be dts The other option which I have not tried is within AC3Filter there is an option to "Detect SPDIF stream in in PCM data" option which might fix this (would need to set it to process PCM ([URL="http://ac3filter.net/guides/how_to_playback_multi_channel_ac3_dts_audiocd"]this[/URL] is not quite what you are trying to do but I think it largely still holds true). I guess you would need to set AC3Filter as the preferred decoder and set MP to Directshow instead of BASS but it might work with your current files. [/QUOTE]
