Hello,
I've remarked that the speakers of the laptop are doing a small noise when
I do not listen music.
If I mute the speaker (mixerctl outputs.master.mute) this little noise
disappear.
I thought this was an Hardware issue. So, I've re-installed the orignial
disk I've received with the machine (which runs windows 10).
But when I run Windows, then there is no strange noise at all from the
speakers. Even when they are idle.
So, I don't think this noise in the speakers is an hardware issue.
So, it seems that azalia is generating some troubles. No ?
An another element ...
This strange noise is not in the headphone when I plug them.
No idea is this is related to the interrups problem.
