kde - all hdmi channels unplugged, monitor speakers

I installed ‘Pulse Audio Volume Control’. I clicked on configuration. It shows all channels as unplugged. Normally without nvidia drivers installed, that should show one channel as ‘plugged in’.

As shown in the other post, the nvidia video drivers aren’t working. So, this could be a related problem.

Need help.

Once I installed an updated nvidia driver today, the HD monitor driver sound was working.

Thanks to all who fixed it…
