That's what most of us likely guess. Or do you hear noise, even if you do not use the mouse, that stops, if the mouse is disconnected? While nowadays even cheap consumer audio interfaces have an amazing good signal-to-noise ratio, even expensive audio interfaces suffer from computer noise. Even a damaged (not completely broken) headphone cable shield could be the cause for allegedly unexplainable computer noise in the audio signal. Most of the times I order something from my semi-conductor dealer, I buy ahead a few very cheap 1⁄4 inch (6.35 millimetres) jacks. Just a few, since the quality of those cheap jacks isn't always the same and apart from this, I tend to use expensive jacks (ream and neutrik) for stressed cables, but at least better jacks than the very cheap jacks. Sometimes very cheap jacks are ok, sometimes they get borked, if they just see a soldering iron at a distance. My point is that sometimes just cleaning jack sockets, replacing jacks or damaged cables, does reduce computer noise. Keep in mind that a connection could become too dirty or cable gets damaged etc. randomly at the same time you update software or you reboot. The noise not necessarily is related to an update or restart, even if it started at the same time. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
