Dell Vostro 2025 64-bit
Ubuntu 18.04.03 LTS Bionic Beaver
Windows 10 Home
1 HDMI port
HDA Intel PCH (?) sound card/chipset (from
aplay – see below)
In Windows I just plug the HDMI cable into the laptop and TV ports and – thanks to the wonders of plug'n'play – it all just works. The TV displays the video. The laptop speakers mute and the much superior sound comes out of the TV.
In Ubuntu, thanks to the novice unfriendly configuration, when you plug the HDMI cable into the laptop port it doesn't even recognise it. No, you have to switch off the laptop, plug in the cable, and then boot the laptop. Then you see only the laptop wallpaper on the TV while the video merrily plays on the laptop. But the sound still comes out of the laptop!
Why is using HDMI on Ubuntu so hard?
Can anyone help me with these issues:
- How to get the video to display on the TV?
- How to get the laptop sound muted and the sound directed to the TV?
- How to post an enhancement request to the bug reporter? It asks me what package is affected. How would I know? Can someone tell me which package to nominate?
