Here is the result of the output from the Pi (Wired gigabit LAN connection, test files from http://www.2l.no/hires/index.html?): 24BIT/192KHZ access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 2 rate: 192000 (192000/1) period_size: 7680 buffer_size: 30720 STEREO DSD 64 - 2.8224MBIT/S access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 2 rate: 176400 (176400/1) period_size: 7056 buffer_size: 28224 STEREO DSD 128 - 5.6448MBIT/S access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 2 rate: 352800 (352800/1) period_size: 14112 buffer_size: 56448 STEREO DSD 256 - 11.2896MBIT/S no setup The first 3 play fine (and sample rate indicator on the Mojo shows DSD), the last one, no sound. I guess S32_LE means it's DOP? OK, the Audiophonics is not for me for sure, wait for the Sabre 9038 HAT from Allo :-) ------------------------------------------------------------------------ SBFan's Profile: http://forums.slimdevices.com/member.php?userid=67994 View this thread: http://forums.slimdevices.com/showthread.php?t=108933 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
