Hey,
Great work with Ubuntu MATE.
I have a Lenovo G50 running the latest version (I hope to complete a compatibility form soon)
I’m not sure if it should work, or I need to enable it somewhere, but when I plug in a HDMI output cable, the audio does not change from analog to HDMI.
I can manually do this from the sound controls and it works fine.
On a side note, when I remove the HDMI cable it still thinks that it’s connected and the windows are floating off screen, it can be fixed by checking for monitors again, AKA open up the monitors setting dialog.
Kind Regards,
Pete
