See here if your card supports HD Audio:

http://www.x.org/wiki/RadeonFeature

if it does then append: "radeon.audio=1" to the kernel command line in grub by editing the /etc/default/grub file. Here i how mine looks:

GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora-system/root rd.lvm.lv=fedora-data/swap rd.md=0 rd.dm=0 $([ -x /usr/sbin/rhcrashkernel-param ] && /usr/sbin/rhcrashkernel-param || :) rd.luks=0 vconsole.keymap=us rhgb quiet enablemodulesig=1 intel_iommu=on kvm-intel.nested=1 radeon.audio=1"

then use grub2-mkconfig (grub2-mkconfig -o /boot/grub2/grub.cfg) to commit the changes the grub.cfg config file

note: This example is for non-uefi systems, see: https://fedoraproject.org/wiki/GRUB_2
