After install of Ubuntu Vidid 15 I can select sound options and then see the HDMI option for output. All is well.
I then run software 'Upgrade' and as soon as this completes the HDMI option is no longer available ?
Is there a way you can 'back out' the updates just applied ?
Is there anything I should do to debug this further.
This is a brand new installation,
Thanks in advance Dave
