I'm using Ubuntu 16.04 on my xps 13, it is working fine except this problem. When I plug headphones in then a constant noise starting and never go until plug headphones out. I read about this problem and tried all of the solutions in this topic and turned auto-mute mode off in alsamixer but nothing has changed.

Can anyone help me? Thanks in advance.

  • I edit my question. I tried every solution in the topic and searched further solutions but they are related to older kernels so I didn't imply them. Jul 10, 2016 at 14:33

I had exactly this same problem with my XPS 13 and found a solutions here:

https://www.reddit.com/r/Dell/comments/4j1zz4/headphones_have_static_noise_with_ubuntu_1604_on/

Essentially you need to do the following: Start up alsamixer, then turn "Headphone Mic Boost" (that's the third control from the left for me) from "[dB gain: 0,00, 0,00]" one step up to "[dB gain: 10,00, 10,00]".

  • Worked for me using Ubuntu 22.04 with Dell Precision M4800, actually any mic may work non muted and with non-zero level, so i used 1%. Thank you.
