I did an apt-get dist-upgrade and got ...
# pluto-av-wizard_188.8.131.52.09072222170_i386.deb (556,555) - HDMI sound support
# pluto-boot-scripts_184.108.40.206.09072222170_i386.deb (234) - HDMI sound support
# pluto-website-admin_220.127.116.11.09072222170_i386.deb (220) - HDMI sound support
I checked for a new alsa release using command - cat /proc/asound/version and I still had version 1.0.17
I checked for a nvidia driver and still had 180.11
Am I missing something?
