Red Hat Bugzilla – Bug 1255577
Crackling sound from speakers on boot and application start (ThinkPad T450s)
Last modified: 2016-05-26 15:35:02 EDT
Description of problem:
Since kernel 4.1.x was pushed to F-22, there is crackling sound coming out the the speakers on every boot. Same if I start Citrix Receiver 13.2, for instance. Some people would describe this as a popping sound.
Version-Release number of selected component (if applicable):
kernel-4.1.6-200.fc22.x86_64, but also other 4.1 kernels.
Steps to Reproduce:
1. Boot F-22 on T450s.
2. Listen to the crackling/popping sound just before Gnome login comes up.
Unexpected sound from the speakers.
Should be silent and it was prior to kernel from 4.1 series.

I wish to confirm the previous comment by Bojan Smojver.
But the issue on my T450s the issue start before selecting the kernel with grub 2.02 release 0.16.fc22
I can confirm this behavior on latest Fedora 23 Beta Workstation.
I opened a bug-report https://bugzilla.redhat.com/show_bug.cgi?id=1268350
It's also listed on Launchpad, Debian BTS, and Suse's Bugtracker.
It seems that a Dev from Suse is working on this issue and is submitting a patch to the kernel. For further Information see my bug-report.
Also there is a temporary solution on https://bugzilla.suse.com/show_bug.cgi?id=943982#c8 for this issue.
Maybe this might help you.
Maybe I should add that I have a T440s but behavior is the same.

Yes, still a problem in this kernel.
