[alsa-devel] Dell XPS 9360 continuous hissing sound

[Paulo Fidalgo]

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_sound_with_headphones

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.

Current kernel: 4.20.7-200.fc29.x86_64

Alsa information:

----
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,

Paulo Fidalgo
