The monitor screen appears black when connecting the PC through the sound bar to the monitor

[Noctis Bennington]

When I connect the laptop to the sound bar hdmi and the sound bar to the monitor, it tries to connect and Ubuntu detects it, but nothing appears on the screen.

My HDMI works as it should, tested directly when it's connected to the monitor. I have tried on a laptop other than my computer with Windows to test if it is something of the sound bar and it works perfectly without problems.

Don't really know what package should be interfering here. Mesa? Mutter?

Sound and display coexisting on the same HDMI cable would be a kernel issue so reassigning...

[Daniel van Vugt (vanvugt)]

Wait, 6.6.5-060605-generic isn't an Ubuntu kernel - do you have the same bug in the default Ubuntu kernel?

Thank you for reassigning @vanvugt.

Sorry, I reported this on 6.6.5 linux kernel. Yes, this happens too in the Ubuntu kernel (6.5.x-generic).
