This is my first time using KDE as my desktop manager. I'm using arch linux as the base installation. I'm not getting sound from Amarok. I went to the system settings and the multimedia but I don't have a hardware tab. I can see that it is using the wrong sound card and everyone says to go to the hardware tab to change the sound card setting. Is there a button you have to check somewhere to get the hardware tab to show up?

Do you have PulseAudio installed? The SystemSettings -> Multimedia -> Audio and VIdeo Settings -> Audio Hardware Setup tab is only there if you have PulseAudio installed, which should be default on Archlinux: https://wiki.archlinux.org/index.php/PulseAudio
