There are a lot of PC USB deficiencies, both hardware and software that can cause these pops due to high latencies or interrupt conflicts. Usually custom drivers have higher latency. Non-Windows ASIO can cause higher latency. Upsampling or decompressing Flac etc. also causes more latency. Dell laptops are notorious for having poor USB interfaces. It is almost impossible to get rid of the pops on these Dells. All USB ports on computers are not equal, even on Macbooks. Macs are the most trouble-free I have found.
