Strangely the command returns amixer: Unable to find simple control 'numid=10',0 So I've runned "amixer -c0" and you can find the output in before.txt
Ah sorry, it was a typo: use "cget" instead of "get".
Then I've runned amixer -c 0 cset 'numid=10' 1 and again the "amixer -c0" and you can find the output in after.txt
Also I've notice that the sound appears after I playing a music on computer and goes a few (like 10 ) seconds after the music stopped.
It sounds like a state after runtime PM.

Hi!
After a bug report on Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=1677353)
When I start t he computer I hears a continuous background noise. The problem is also described here: https://wiki.archlinux.org/index.php/Dell_XPS_13_(9360)#Continuous_hissing_s...
I need to issue the command `amixer -c 0 cset 'numid=10' 1` to solve the problem, but every time I reboot the computer I need to run it again. This has been happening for quite some time, but I've been post-poning the bug report.
What is the original value before setting this amixer command above? You can get via "amixer -c0 get numid=10'.
Does the noise again when you restore the value after setting to 1 in the above?

They advise me to contact you, to see if we can get a solution on this.
Note: The computer also does not recognise (switch to) when I plug an headset.
If you need more information, I'm eager to help diagnose and help to solve this, but I have no Kernel programming skills, other than that count on me.
Kind regards,
