so borrowing from Pippin Packetized network traffic->NIC->Network driver->flac -> sox ->decode buffer->play buffer->aplay -> pcm -> kernel -> drivers -> device There is code to fill a decode buffer and then copy that to a play buffer, perhaps the efficiency of that is different between flac and wav. Is sox decoding a batch of data at a time ? I've always found wav to sound better than flac whether it was on pc or sbt or apple Touch, flac would have a difference in timing which wasn't present with wav. I use flac for archive, so am happy that after conversion the data is the same, it's just the effect of decoding at the same time.
