I would say, when playing games, if you get audio crackling, try a different kernel such as Liquorix (software.opensuse.org//download.html?project=home…). I’ve had that issue on my hardware across multiple distros, and this kernel solves it.
I believe it’s something with a kernel parameter regarding scheduling, specifically as noted in this features list (liquorix.net/#features)
High Resolution Scheduling: 1000hz tick rate for precise low jitter task scheduling.
You may or may not get this issue with your hardware, but if you do, then this is something you could try.
