iMäcen Posted December 22, 2006 Share Posted December 22, 2006 Can anyone recommend a soundcard with digital output where AC3 and DTS passthrough works? I have tried with Turtle Beach Advantage Micro and Edirol UA-1EX, but none of them work with passthrough.

iMäcen Posted December 22, 2006 Author Share Posted December 22, 2006 Thanks! I Googled, and found: "TOSlink optical digital output allows AC-3 and DTS pass-through".

macgirl Posted December 22, 2006 Share Posted December 22, 2006 Cool EDIT: I tested with my USB Sonica Theater and it passes AC3 (I don't remember if I have a DTS DVD ) Although it does not have drivers (which are realy only to have Surround Settings) it can set it as Dolby Digital/AC3: Difference with Sonica and Transit is that Sonica has Coaxial SPDIF and Transit has Optical output Link to comment https://www.insanelymac.com/forum/topic/36566-soundcard-with-ac3-and-dts-passthrough/#findComment-260241 Share on other sites More sharing options...

iMäcen Posted January 6, 2007 Author Share Posted January 6, 2007 Now I have another problem with the soundcard. Passthrough in VLC works if I enable SPDIF. But I would like it to work in MPlayer ( http://www.mplayerhq.hu/ ). When I add "-afm hwac3" to the command line, all I get is choppy sound. The sound is just like the sound I get for half a second when the soundcard changes from PCM to AC3/DTS in a player where passthrough works. Can you please try if you get any passthrough in MPlayer? If you have a xvid with ac3 sound...

ulion Posted July 27, 2007 Share Posted July 27, 2007 i am working on passthrough ac3/dts with mplayer on mac osx intel now i have a modified mplayer by myself accounding to VLC's source code, and have a working passthrough with s/pdif output. but the subtitle flickering on most time when fullscreen, i did not known whether it cause by my old mplayer source code (1.0rc1) or by my code. i will try newest svn mplayer code and try to resolve the flickering problem and release the patch later. any one interested in the develop can contact me by email: ulion2002 <> msn dot com Link to comment https://www.insanelymac.com/forum/topic/36566-soundcard-with-ac3-and-dts-passthrough/#findComment-415912 Share on other sites More sharing options...
