This is a persistent misunderstanding of what was going on in
issue #2215. The USB network adapter was a minor factor in whether or how often the pops and clicks might occur. What software was running was a much bigger factor - brutefir was a reliable trigger on both volumio and raspbian unless it was pinned to a single cpu core. With the same hardware running piCorePlayer I never managed to make it pop/click despite streaming the highest rate PCM and DSD files I could find on 2L's free samples, so it certainly could be suitable for audio.
