My bet is that all Astros has this issue, to about the same extent.
By their nature, digital signals switches between low and high - zero or one - as immediately as possible. If that leaks into analogue audio, you get snap, crackle and pop. If desired, see, for example, the Wikipedia article on square waves, for more on how digital signals looks from an analogue perspective.
Anything with digital signals and analogue audio has some of this challenge. Things that are actual computers, tends to have more of it. At the clock speeds involved, circuit board traces wants to be (very short range) antennas, making it hard, thus expensive, to stop this noise from going everywhere inside a device.
I think we're seeing an example of the difference between when big brands can spend a million dollars on testing, and when you have to rely on data sheets, and maybe an industry partner more focused on done than on actually good. These things are tricky, so I'm not pointing fingers, just trying to estimate reality.
