I have a Radeon 3650 graphics card with built in sound support, and would like to listen to sound through the HDMI connection. Though, when selecting that sound output, no sound can be heard. Selecting the intel motherboard sound and listen via e.g. earphones works fine. I am using Fedora 15 with default configuration. Is it possible to get the Radeon 3650 HDMI sound to work?

Hi there!

HDMI audio output is disabled by default. To enable it you need to pass the radeon.audio=1 option to the kernel at boot.

To do so:

  1. Edit /etc/default/grub and add radeon.audio=1 to the GRUB_CMDLINE_LINUX line, it should look like: GRUB_CMDLINE_LINUX="... radeon.audio=1 rhgb quiet"

  2. Update grub's config: $ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

  3. Reboot.

I hope this helps.
