Sound loss is on-off-on-off in more or less equal intervals. Very frustrating. Every day brings a different "style" of sound loss, but lately almost every day there is sound disruption; sometimes entirely no sound and most often on-off-on-off-on-off all the time. The PC desktop is Fujitsu Made in Germany. So.... The sound loss happens on all browsers, all websites, videos, music, anything. I even tested continuously at Control Panel - Sound - Sounds, especially with longer "chime" test sounds, all kinds of PC sounds and so as yu can see also testing PC sound disrupts sound so the even short sound (test) begins with sound then nothing and then a bit at the end, or nothing at the beginning and some sound at the end, or some sound at the beginning and none at the end. I found one or two places where people complained about the same or similar issue with disrupting sound, but I could not find a solution. So this is clearly the entire software thing, maybe even hardware issue? But where do I start? Should I uninstall the sound driver and install it aain? But will I be able to install it once it is uninstalled? And is this an issue with a driver? I don't want to start checking everything and I definitely can not buy a new PC. This PC is good, I think, just has this weird sound issue for the past year or so. Perhaps someone knows where to look, before I begin suspecting a... conspiracy :-) Some days sound is on, without problems,but then...now several days is bad.
One more thing, sometimes I turn the room light off in the office room and my PC makes a sound (reacts to it). Not always just occasionally. No weird connections. Rarely though. I just did that but no reaction to the light.
Also, when I opened a MIXER on my PC (sound icon at the footer). Also in the past something has deleted my foreign language typing installed icon and at some point the mixer icon at the footer was nowhere to be found, but now it is back.
Take a look at the other attached screenshot which displays both the sound testing facility and mixer. So when I click on TEST (sound test) button, the sound (partly disruptive) sounds and the green volume "towers" only lit up at the "Speakers" and "System Sounds" towers, but not at the Firefox tower. I caught the green with PRTSCR button and it shows up at the screenshot. Yet I don't think this is Firefox issue since other browsers get exactly the same sound problem.
Also, and I don't know whether this has something to do with sound, but about several months ago I lost ability to print on all browsers in my PC: Firefox, Opera, IE, Chrome, Apple etc. all of them stopped printing and were and still are crashing upon "print" command, except... Vivaldi browser. This is Windows 8.1 with some updates, but some updates are not loading or updating.
