HDMI Audio

Radeon HD 5740 does not output sound through an HDMI connection to a TV. I checked the sound channel and there are no sound channels displayed.

Added an entry in /etc/lilo.conf under the Linux entry:

# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/sdb2
label = Linux
append = "radeon.audio=1"
# Linux bootable partition config ends

and created a new file under /etc/modprobe.d/ called radeon.conf. In it:

options radeon modeset=1 But no change.

Realized editing lilo.conf needs to be updated using the following command

/sbin/lilo -v

Still no change.
