So I've looked at many of the other forums but nothing I've seen so far has eliminated my issue. As soon as I boot up my laptop, Lenovo T440s, I start hearing a pop then a loud continious hiss that seems to cut out anytime the sound adjusted. This only happens when I boot into Ubuntu, when I boot into windows I do not have this issue.
I tried muting my mic, I tried alsamixer, neither worked. The pop and hissing does not happen over speakers, only headphones, and it happens with the same intensity no matter what my volume setting is, even when it's on mute.
When I open 'sound settings' it stops, but nothing I've done there has prevented it coming back. The only thing so far that stops it is if I have other sounds playing. It almost seems like it is a result of the soundcard not being used. Any ideas out there? or forums that already dealt with this that I did not see? Thanks
