I need help with my Samson Meteor Mic USB microphone, which I have connected to my Raspberry Pi (running Raspbian). I'd like to use it for recording, but I keep getting an occasional crackle in the recording. Just brief clicks but they do make the recording useless. I normally use Audacity, but I've tried the arecord utility, too - same result. It sounds like the data stream cutting out for an instant every few seconds.
The microphone works fine on my windows laptop, and also on my Ubuntu x64 laptop. The problem occurs only on the RPi. Any idea what could help? Is there some input buffer on ALSA which I can increase in size? I've tried increasing the input buffer length in Audacity - didn't help.
Okay, I've figured out a fix. I set Audacity to record at 48 kSps instead of the usual 44.1 kSps. No crackle then Unfortunately, since I need my recordings at 44.1 kSps, I have to resample them but at least it works now.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Thanks a lot for any suggestions!
