Hi!

I have problem with my new notebook Lenovo Ideapad 720. I installed on it Manjaro. Headphones are cracling every time when they are plugged in/out or notebook is turn on/off. In addition, there is not too loud but audiable white noise which is presentwhole time headphones are plugged in. I tried to mute microphone, mute everything in alsamixer and noise is still present. I tried other headphones and all of them works the same.

Thanks you in advance for every advice.

...and i assume it is not happening on windows?

not sure if it's a hardware or software issue.

in alsamixer, press F5 to get all channels, and go through them, see what they do, mute them with 'm' (you will see 'MM' in channel).

give us the output of

Code:

lspci -k | grep -A4 Audio
uname -rv
aplay -L
