I have no idea how old you are, nor how you know how old I am, but I always assume people can find out anything they like about me on the 'net if they try.
Anyway, I didn't know you were using pcm. So although some of the numbers you quote are over my head (and beyond my failing hearing), that may be right. See philippe's explanation a few posts ago for why pcm may not behave well, and try flac instead? LMS 7.9 on VortexBox Midi, Xubuntu 14.04, FLACs 16->24 bit, 44.1->192kbps. LMS & Squeeze2upnp to MF M1 CLiC (to MF amp & ESLs) & Marantz CR603 UPnP renderers. Minimserver (server) & upplay (control point) to same renderers & to upmpdcli/mpd PC renderers. Squeezelite to Meridian USB Explorer DAC to speakers/phones. Wireless Xubuntu 14.04 laptop with firefox/upplay or Android 'phone with Squeeze-Commander/BubbleUPnP controls LMS/Minimserver. Have a Touch with EDO, and a spare, but don't use. ------------------------------------------------------------------------ PasTim's Profile: http://forums.slimdevices.com/member.php?userid=41642 View this thread: http://forums.slimdevices.com/showthread.php?t=102496 _______________________________________________ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
