Hi all,
I am currently running Ubuntu 20.04 on my XPS 15 7590. Here everything
works like a charm. When working at my desk I connect my monitor and
peripherals using my WD19TB docking station connected over Thunderbolt.
Here I run into two (small) problems.
1) I have no audio from both the speaker connection and the headphones
connection. Both are recognized by the OS, but there is no audio. I have
been playing around with ALSA, but without any success.
Now using bluetooth audio, but I would really like to use a wired audio
connection when connected to the docking station.
2) When the docking station is connected to an ethernet cable all works
as expected until I shut down the computer. A few minutes after I shut
down the computer my home network completely appears to freeze / hang
up, every device on the network loses its connection. Disconnecting the
ethernet cable from the docking station or (re)starting the laptop
solves this problem. I notice the left led on the ethernet port (link)
of the docking station stays on after the computer shuts down (when
running Windows 10 it does not). When using a USB ethernet adapter
directly connected to the laptop (being disconnected from the docking
station at that time) the problem does not occur.
Now connecting to my network using wifi, but here too - I would really
like to use a wired connection when connected to the docking station.
I have experienced both problems with Ubuntu 20.04 - also with Ubuntu
18.04 and several Fedora versions. When installing and running Windows
10 everything works as expected.
Has anyone else experienced these problems and maybe solved them? Or
does anyone have an idea that might solve these problems?
Thanks in advance.
