Besides a DD track it also support a 24-bit LPCM audio track. I know xine has support for LPCM (16-bit at least), and I have seen it work (in "The Wall" for example). Well, the 24-bit LPCM does niet seen to work. Xine thinks it is 16 bit 48 Khz LPCM sound... and the receiver only gives noise :(. My soundcard does not support 24-bit 96 Khz playback, but xine should at least be able to downsample it to a usable format, or simply transport it in a raw form to SPIDF (like AC3 passthrough). My receiver should be able to decode this. I use xine lib 1.0-rc2 and gui 0.9.22.. ---------------------------------------------------------------------- >Comment By: Michael Roitzsch (mroi) Date: 2004-07-03 20:41 Message: Logged In: YES user_id=552060 Could you try this again with xine-lib 1-rc5?

Thanks for fixing it. I guess you are the first *nix player to have it working ;) Still, one thing: The stream information still shows 16 bit sound. It pays very good though! It is sad that I can't check if the soundcard is really putting out 24-bit's. I guess I have to take your word for it (debugging does not show any conversion). When I make the calculation from bitrate to samplerate, the 24-bit realy work: 2304000 = 2*(24 bit *48000 Hz) :D Great work! ---------------------------------------------------------------------- Comment By: Miguel Freitas (miguelfreitas) Date: 2004-11-19 13:40 Message: Logged In: YES user_id=148691 This bug entry is believed to be fixed in cvs. Please reopen it as needed. ---------------------------------------------------------------------- Comment By: Michael Roitzsch (mroi) Date: 2004-07-04 13:59 Message: Logged In: YES user_id=552060 Sorry, I just saw the 24bit support in audio out and in liblpcm and thought this would work now.
