[opensuse] Giving priority to Amarok

Good evening Sometimes, when I'm doing something disk- or possibly CPU-intensive (big Steam downloads seem to be a major culprit), music I'm listening to in Amarok will pause for a second or two. This is pretty irritating and what I want to do is tell my PC that Amarok should always have priority so that it doesn't happen. I have a couple of questions around this: 1. Should I use renice for this, and if so, how do I ensure that Amarok always has the new niceness that I set? 2. Is it sufficient to renice only Amarok, or are there associated processes such as pulseaudio that need to be similarly reniced? Many thanks in advance for any advice. Kind regards, Huw
