You are welcome, About performance, Crackles and pops - if format is supported form your DAC and you restarted it after changes - are symptom that you are asking too much from your system, probably Atom is not adeguate for server purpose, if upsampling. Firts things to try is increase the buffer size in Squeezelite (with 192/24 wav a minimal setting is -b 16384:16384, but if you have enough memory, you could even double them or more) and use greater period size in alsa (lower period size = greater CPU usage). I use an old AMD Dual core 6000+ 3GHz with 4 GB Ram, Ubuntu 15.04 and I could esaily upsample form 44100 to 384Khz and decode form any codec to WAV or AIFF, SOX is sometime using 50% of CPU, but never had a crash of LMS. Realy strange Squeezelite crash, if launched without -u, it should use very, very low cpu (< 1%) and less than 50 Mb (depending on buffer size). A lot of people use it on a Futro S450, that's a sempron Thin Client, with 1 GB RAM with great results, I have an AlixBoard and an Atom miniPc and never had a problem, works very well even on tiny ARM devices. Coul dyou please post the squeezelite-R2 command line and maybe its log? Thanks a lot. ____________________________________________________________ SB+, Klimo Merlino + Kent Gold, Monitor Audio Studio 20 Gold SE+, Klimo reference and DIS Interconnect. ------------------------------------------------------------------------ marcoc1712's Profile: http://forums.slimdevices.com/member.php?userid=34842 View this thread: http://forums.slimdevices.com/showthread.php?t=105309 _______________________________________________ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter
