To be honest, I never heard of the USB DAC card would hate to spend money only to amplify the crackling and pops. But a different sound card is a possibility. You recon this one is compatible with Peppermint?
As I said, I'm coming to terms with linux (migrating from windows), so am a novice when it comes to the terminal commands. have managed a few tasks with help from you tube and various websites. Don't know how to go about changing kernels ... tis all greek to me.
I JUST WANT CLEAR SOUND!!!

And I thank you for all the advice.
