Be careful - the standard Touch kernel only supports 96k sample rates with the built in devices - you will need the EDO kernel for 192k and then only on spdif/usb, the built in analog won't work. I very much doubt you will really get above 96k though with the other devices as there's no kernel driver support for them. The alsa layer can do resampling, but I suspect this will result in lots of cpu load and no real benefit. You should could test against squeezeplay or squeezelite on linux for 192k support - I would expect this to work with your server as long as the send buffer is large enough in your server - the clients will wake approx once every 100ms if starved of data, so you want to make sure your server can maintain a streaming rate. ------------------------------------------------------------------------ Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=97244 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
