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
Still no change.
