major memory failure by me Just remembered 3 years ago, i flashed my card with prodigy 7.1 firmware in order to play bit-perfect over spdif. The goal was to be able to play wave files that were encoded with either dts or dolby digital straight to a receiver through a digital cable with out windows or the soundcard resampling it and screwing it up. The files come from http://www.sr.se/multikanal/english/e_index.stm I was just testing this with mplayer to see what i could get. mplayer Saga.wav -ao alsa:device=mplayer plays it but decodes it and sends the decoded stuff over pcm 2 channel... Code: AUDIO: 44100 Hz, 2 ch, 16 bit (0x10), ratio: 176400->176400 (1411.2 kbit) Selected audio codec: [ffdts] afm:ffmpeg (DTS) ========================================================================== Checking audio filter chain for 44100Hz/2ch/16bit -> 44100Hz/2ch/16bit...

Video: no video Starting playback... this guy had my same isssue but didn't report success http://www.avsforum.com/avs-vb/archive/ ... 67811.html this also fails Code: sh-3.00$ mplayer transitWS44_1kHz16bitDTS.dts -ao alsa:device=iec958 -ac hwdts

My card is fine. A user on the mplayer users list says MPlayer 1.0pre6-3.3.5 is "very, very old." HappyTalk et al to the rescue... http://mysettopbox.tv/phpBB2/viewtopic. ... r&start=15 Now ac3 television and ac3/dts movides play over spdif for me. here is what I use to play xvid with ac3/dts out to spdif on the chaintek av-710 in R5B7: Code: mplayer -fs -zoom -quiet -vo xv %s -ao alsa:device=iec958 -afm hwac3
