To play that file you must then resample it and convert it to 24 bit depth.

Probably is not the DAC but only the driver of the USB/I2S having problem with 32bit streams and this is the strange thing, becouse specification says that any device (driver) should receive and handle any bit depth form 8 to 32 bit, just discarding the less significative bits when greater than the real capaility or adding padding zeroes when smaller. ________________________________________________________________________ Author of C-3PO plugin, Squeezelite-R2, Falcon Web interface - See www.marcoc1712.it ------------------------------------------------------------------------ marcoc1712's Profile: http://forums.slimdevices.com/member.php?userid=34842 View this thread: http://forums.slimdevices.com/showthread.php?t=97046 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
