Title:
External HDMI monitor audio always reported as "unplugged"
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello my Ubuntu friends,
I can no longer play sound over my external HDMI connected TV.
The image displays perfectly, but all the HDMI output devices are
listed as "unplugged"
I have spent a huge amount of time trying every solution that Internet
searching will bring but this has changed nothing.
I have tired all available video drivers, including Xorg and NVIDEA
396.26, 340.107, and 384.130.
This failure is recent because in the past I could play both audio and
video through the HDMI connector.
The laptop is dual boot with Windows 10 and the HDMI works perfectly
on that OS, although I rarely use it...
I am wondering if upgrading my Xubuntu to the latest LTS could
potentially solve this issue, but I fear such an update since I depend
on this computer and an outage would be very hard for me...
Any thoughts would be great.
Thanks for making Linux great!
Bob
