I have encountered a strange problem. About 6 months ago, I added a USB
sound adapter and alsa to an ARM based linux system. I used aplay to
play wav files successfully.
Now, the playback has a crackling noise in it. I can not find anything
that has changed. A few units still play with no noise, but I cannot
determine any difference between them and the ones with the noise.
One odd thing is if I run an application to make the CPU busy while
playing the audio wav file, the noise seems to go away. Any ideas on
where to look for the root cause?

I have had a similar experience using an AudioQuest DragonFly and a CuBox i4. In my case, errors were reported in syslog. Do you show any errors there?
Do you have any other USB sound cards to try out?
