Title:
[GA-78LMT-USB3 6.0, ATI RS690/780 HDMI, Digital Out, HDMI] No sound at
all
Status in alsa-driver package in Ubuntu:
Confirmed
Status in focal package in Ubuntu:
New
Bug description:
The HDMI audio on the onboard ATI RADEON 3000 (RS780 driver, GA78LMT
motherboard) does not work without tweaks in GRUB.
Expected behavior: sound working over HDMI.
Real behavior: no sound at all.
Solution: I installed "GRUB Customizer" and put the following command
in the kernel parameter (which I found after a lot of research):
"quiet splash radeon.audio = 1"
This needs to be resolved urgently, it can alienate novice users.
