No, I did not and it resolved the issue!! Awesome!

What does this option do? Does it have any side effects?

This disables snooping mode. It's rather a problem of controller, not the codec chip. There can be a slight performance decrease.

If this is the final solution, I will communicate to the other users this solution.

Looking at alsa-info.sh, it's a new chip, and the workarounds for Intel PCH & co aren't applied to it yet. That's the likely problem. Could you try the patch below without snoop=0 option?
