Razer Nommo Crackle

Hi,
I purchased the Razer 2.0 Nommo Chroma speakers back at the end of June 2019 and have loved them and had no issues since receiving them. Recently, within the last 2 weeks, they have started to consistently crackle when any audio is playing. Nothing was changed in their setup, this has just randomly started happening. I haven't altered any settings or anything on the speakers themselves so unsure why it has begun. I've seen other people have had this issue so wondering if there is a solution for this you can help with?
Thanks,
Lawrence
