Yes, I know all about getting bit errors across the network. TCP checksums and ethernet frame CRCs can be corrupted in subtle ways especially when your switch is doing vlan tranlations and the frame checksums are being recalculated. This type of thing doesn't happen on home user networks so it's not really as big a deal. We're also talking about very very low bandwidth rates of only a megabit or so. The point of all this is the % chance of this happening in a an audio stream AND not being completely obvious as garbled/static frames is so low it's not worth talking about. Un-caught corruption in the IP/packet level will likely cause completely obvious garbled audio output. -- SuperQ ------------------------------------------------------------------------ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=60910 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
