Bug#800694: linux-image-4.1.0-2-amd64: crackling sound while booting Testing on T440s
Package: linux-image-4.1.0-2-amd64
Version: 4.1.6-1
Severity: normal
Tags: upstream
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Just booting into a freshly updated Debian Stable to Debian Testing on every
reboot this unhealthy sounding crackling noise accours
* What exactly did you do (or not do) that was effective (or
ineffective)?
Just do a reboot or shutdown and boot
* What was the outcome of this action?
Crackling sound which sounds that it could damage internal speakers
* What outcome did you expect instead?
Not a sound. On my now running debian stable machine just a very silent
plopping occurs (never noticed before maybe just because I am aware now because
of the crackling while testing was installed) So just a very silent sound when
speakers get initialized. As normal when I was running stable or Ubuntu LTS
14.04
I will also Add what I posted on launchpad because this also effects the same
package
"Machine is an T440s. Todays Daily Build of Ubuntu Unity, but was also on
Ubuntu 15.10 Beta
While booting into Desktop a crackling sound appears (like connect speakers or
headphones to a music player if not muted) and it sounds very unhealthy to the
speakers.
When using Debian Testing I have the issue while booting. With Fedora 23 Beta
its also the same while booting. Always this unhealthy sounding crackling noise
and then working normal after booting is finished. Muting is working, volume
selecting is working without any issues, just while booting to Desktop there
seems to be something not working properly while initializing internal
speakers.
On latest Ubuntu 14.04.3 there is no crackling while booting. Just booting
normally into Desktop. You can hear that the speakers are initialized with a
very silent plopping sound (as also in Debian Stable) but I think I start
observing it just because of this crackling sound before. I was running Ubuntu
14.04.2 plus LTS Enabled Stack before and there were also no such issues.
