It's been years since I have had a sound problem on a Linux Mint machine. About a week ago, I was running my desktop when the power went off at my house for a little while. While waiting for power to be restored, I remembered I needed to vacuum my computers out to eliminate the build up of dust in them. (It's a dusty environment.) So, when the power came back on, I first vacuumed all my desktops, opening them up, and sucking out any dust inside them. When I later powered up my main computer, the sound is messed up. It shows the sound at 150%, but in reality the sound is fairly low, and the background music almost completely hides the voices of youtube videos, movies, and streaming. Also, it sounds kind of squeaky and hisses. Things sound strange and subdued. Also, and this is weird, I have a video I downloaded from YouTube a while back which I have never been able to hear any sound on at all, except for the beginning banner music which is perfect, then dead silence thereafter as the guy on the video begins to talk. It is a MP4. But as of now, it is the only video that is suddenly playing perfectly and I can finally listen to the lecture! Whereas the sound is messed up on all my other videos. It doesn't matter what video player I try to use, although my favorite is VLC.

I've been trying to fix this, although I really have no idea how. Before I realized how widespread the impact of the problem was, I started by deleting the VLC file in .config, which didn't work. Since then, I have tried quite a few things, but maybe not the right things. Anyway, the other night I decided to just re-install Linux Mint from my DVD copy, while preserving my /home partition. No change. I tried installing Linux Mint 19. Same problem. So, reinstalled Linux Mint 18.2 because I am not ready to jump to 19. My sound is foobarred, except for the one .MP4 video that I mentioned and my sound effects of my machine.

Does any of this ring any bells for anyone as to what is wrong? -Or what to do to figure this out? It seems to me that the problem has to either be burried in some kind of .config file in my /home directory or the vacuum cleaner maybe knocked something loose inside the machine....BUT if that were at all true, WHY DOES THAT VIDEO PLAY PERFECTLY??? -The one I mentioned that would never play sound at all before....

Here's some more data from my machine, and thanks for your kind help:

Hi lemmingNO3.

I have an idea what may be wrong, but first I want you to delete the files in ~/.config/pulse then issue pulseaudio -k in the terminal.

If that fixes it (meaning it puts things back to the way they were) run pactl list sinks again and post the results back here.

If it doesn't work, I'll have an answer shortly.

Re: Power Failure - Vacuumed Computer - Sound Messed Up

I should have mentioned in the first post that you should never use a vacuum to clean out sensitive electronics. The vacuum nozzle builds up a static charge quickly and it can discharge and fry something on your motherboard. Use compressed air instead.

On to the problem. I'm thinking your default sample rate has changed (from 44100Hz to 48000Hz) but not sure how. You can test this with cat /etc/pulse/daemon.conf | grep default-sample-rate and if that still shows 44100, I have more work to do.

Does any of this ring any bells for anyone as to what is wrong?
It does, and it is very likely a hardware rather than software problem: I'm fairly certain you are experiencing the effects of a loose/broken ground connection. This could be as easily fixable as through cleaning and/or pushing in further the 3.5" jack to your speakers...

I.e., you describe "but in reality the sound is fairly low, and the background music almost completely hides the voices of youtube videos, movies, and streaming"; cancelling out of vocals is the symptom you expect for this issue: if the left and right channels of a stereo plug/connector are still connected but the ground contact is broken you (may, depending on wiring) end up listening to the difference between left and right channels. With voice/vocals normally mixed (mostly) in the center said difference is (near) zero hence cancels out; the rest will also sound low, muffled, reverby, but the voice/vocals issue is most definite.

External confirmation of the issue: https://electronics.stackexchange.com/q ... tially-unp.

That other video which vice versa gained vocals seems to not fit but is too neatly opposite to for now consider to not be this same issue.

First thing to try, then, is to replug and/or clean the jack to your speakers; possibly with a bit of alcohol. I have experienced the issue myself as a result of dislodged dust getting in the (female) 3.5" receptacle connector. As such, also repeatedly twirl the jack, plug/replug, again possibly with some alcohol.

It might of course not be all that simple; you may have actually damaged something. But for now concentrate on a dust bunny breaking a ground contact somewhere...

Very informative post rene, thanks!

That one suddenly working video had me thinking the OP had been forcing one sample rate (44100 or 48000), and is now forcing the other (most likely through an asound.conf file) and that one video is the only one the OP has that was created at that new rate. I still don't know much about the inner workings of sound on computers but this seemed like a possible scenario.

I now think you're more likely correct and the reason for the one working video was simply it was just mixed opposite of the way most poeple do it (i.e. vocals not mixed into both channels equally in this case,)

[justme@ispy] ~$ cat /etc/pulse/daemon.conf | grep default-sample-rate
; default-sample-rate = 44100
[justme@ispy] ~$

BUT! The suggestion about the sockets being dirty inside, made me think I hadn't checked to verify my headphones were actually working. So, I removed the headphones, dug my old speakers out of storage and hooked them up, and audio is working correctly now!

I'm going to try and check if my stereo socket is in fact dirty or has some moveable particle of something inside it. And I'm going to test my headphones on something else yet, also. But the problem is gone!

Why that one .mp4 had no sound months ago, and now does, is still a mystery, but maybe some upgrade solved that problem, and I've not returned to test it to know it actually works now.

So, I am going to call this solved!

I want to thank you guys for jumping on this and all your great ideas! And I will certainly remember about not vacuuming things! That was a new one for me.

Sounds like it is/was your headphone jack which is dirty or, as mentioned, simply was not fully-completely plugged in.

That video that experienced restored voice: seems to make sense if voice was placed in either left or right channel only -- although it not being audible before the problem started then doesn't really. So, strange one that, but good to hear you have things functional at the moment.

Yeah. That single .mp4 thing is going to haunt my mind for some time to come. :D
