My system (E45M1-I Deluxe with AMD onboard graphics with 4GB RAM) running Ubuntu 12.04. My problem is I have no HDMI sound if using the opensource drivers instead of fglrx.
- to remove and purge all
pulseaudiopackages and reinstalling alsa.
- resetting audio settings with
dpkg --configuration -a
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"to grub config
- enabling the device via
alsamixer, although I only see S/PDIF instead of HDMI
- editing asound.conf with the card and device number
Are there recommended steps to go about installing HDMI sound?
