[SOLVED] Persistent Static noise coming over monitor speakers when playing audio

[BestOrange]

Hi all,

Been using linux mint for a couple years now. Built my own PC a couple months ago and decided to keep using it as my daily-driver.

Since I have started using this computer setup, I have had random instances where the monitor speakers will emit a static... echo? Of the audio that's being played. Sometimes I can play music for several hours with no unwanted noise at all only for it to start making noise out of nowhere.

Regardless of whether the noise is happening while playing music, I cannot recall a single time I have started up the system where the chime that plays when I log into Cinnamon didn't sound garbled and staticy.

I have held off this long on making a bug report because it is so finicky and random with what triggers it or what cures it. I was hoping I could find some sort of pattern with it, but any triggers or cures only take effect some of the time.

The only consistent trigger I have noticed is the onboard voice synthesizer, which is especially problematic because I rely on the text to speech program for school.

I have noticed that having discord booted up, either the app (Flathub ver 0.0.45 atm), or the web browser (Firefox System Package 123.0.1+linuxmint1+virginia) version, will have the noise intrude shortly after.

In the past, restarting the system did remedy the persistent noise when I would play music (although again, there is always static during startup with the Cinnamon DE startup chime), but that no longer works as a solution as of a couple days ago. Maybe of Note: I did apply a host of system updates around this time.

The other day I got it to stop by opening up the display settings, lowering my frame-rate, then moving it back up to 99.98 HZ. I have not been able to replicate this.

This noise does not occur over HDMI (also through the graphics card), through audio played over my case's front headphone jack, or through integrated graphics (using the same wire). Only through DisplayPort when plugged into either GPU DP socket.

I will attach the monitor model, system info, and system-logs labeled "important" at the bottom of this. If there is any information I could provide that would be helpful, please don't hesitate to let me know. I'm a CS student, so I would say I'm not totally in the dark, but I have never meaningfully engaged with LM forums or filed a bug report before.

Any and all help, suggestions, advice appreciated. This has been driving me CRAZY.

The only consistent trigger I have noticed is the onboard voice synthesizer, which is especially problematic because I rely on the text to speech program for school.

Welcome to the forum, BestOrange.

What do you mean by "the onboard voice synthesizer"? What is that?

Have you tried the Bad Sound Fix Tips #1 about disabling the timer-based scheduling pulseaudio now uses? (Scroll down the page to the Bad Sound Fix Tips.)

This noise does not occur over HDMI (also through the graphics card), through audio played over my case's front headphone jack, or through integrated graphics (using the same wire). Only through DisplayPort when plugged into either GPU DP socket.[/b]

And you have tried a different DP cable?

As a start, I suggest you upgrade to the 6.5 kernel available in Update Manager. A 7000 series Ryzen needs to be using the newest available kernel.

I also recommend you run

Code: Select all

sudo update-pciids

to get the latest names available for your GPUs.

[BestOrange]

And you have tried a different DP cable?

I have not. Money is tight, and I am inclined to think the cable is okay since it works fine when I plug into my MoBo and use integrated graphics. However I do intend to try it if software fixes prove ineffective.

What do you mean by "the onboard voice synthesizer"? What is that?

It's listed as "screen reader" under accessibility options. I primarily use it to speak text from PDF using Okular.

The program it starts up is called "speech-dispatcher' under system monitor.

If the voice synthesizer so much as speaks a word, the audio issue is amplified by a couple orders of magnitude for any audio playing until I manually kill "speech-dispatcher," even if the voice synthesizer is not reading anymore.


Following along one step at a time to pinpoint the solution in case of success.

As a start, I suggest you upgrade to the 6.5 kernel available in Update Manager.

Done. Rebooted. System info notes Linux Kernel 6.5.0-25-generic.

I also reccomend you run ... to get the latest names available for your GPUs.

Done. Thank you for that. That was annoying me lol.

Have you tried the Bad Sound Fix Tips #1 about disabling the timer-based scheduling pulseaudio now uses?

Thank you for pointing me towards this. Attempted to implement these with varying levels of success:

*Tip #1
Done, although it did output a warning:

Code: Select all

** (xed:7641): WARNING **: 18:38:40.693: The specified location is not mounted

*Tip # 2
N/A

*Tip #3
Done, with a similar warning as above.

Code: Select all

** (xed:7847): WARNING **: 18:42:28.920: The specified location is not mounted

*Tip #4
The terminal did not like this one. Couldn't even fine the config file.

Code: Select all

** (xed:8040): WARNING **: 18:45:10.662: The specified location is not mounted

   ** (xed:8040): CRITICAL **: 18:45:18.963: xed_conversion_error_info_bar_get_encoding: assertion 'menu' failed

I do not understand fully what those warnings mean, but they seem significant, no?

#1 was the only one I suggested doing. I did not suggest trying all four tips. I specifically said #1.

At what point did you get that warning? I would need to see the entire output to get an idea of what you are referencing.

You said you are using speech-dispatcher so I don't understand why you would try to disable it.

[BestOrange]

I did not suggest trying all four tips. I specifically said #1.

I understood your suggestion. However, the other fix tips seemed adjacent enough to my particular issue that it felt prudent to rule those out.

At what point did you get that warning?

Immediately after typing the command.

Code: Select all

 ~$ xed admin:///etc/pulse/default.pa

** (xed:4751): WARNING **: 10:22:59.839: The specified location is not mounted

It is the next immediate output after that particular input. Above is trying it on a fresh boot.


The scenario is the same when I try to access the speech-dispatcher:

Code: Select all

~$ xed admin:///etc/default/speech-dispatcher

** (xed:3394): WARNING **: 10:09:53.924: The specified location is not mounted

Only the txt file that opens up after issuing this command gives me a "file not found" error.

However it does not give me the "critical" error from my last post after trying again with a fresh boot.

You said you are using speech-dispatcher so I don't understand why you would try to disable it.

Two answers:

• 1 - To isolate the problem. I still don't know what triggers it. If I disabled speech-dispatcher and the sound issue went away, I would be able to ask better, more pointed questions as well as let future people with my problem follow the same steps.

• 2 - Expanding on my previous post: The sound issue becomes so terribly severe the second I attempt to perform any text to speech action on my computer that the speech-dispatcher application is functionally non-existent. If disabling it worked, I would at least have clear sound coming from my speakers while I explore other accessibility options.

Please go to File Manager and check to see if you have /etc/pulse/default.pa in your File System (root) directory.

Code: Select all

/etc/pulse$ ls

I think I do, if I understood you properly. It seems to open with no problem as far as I can tell too.

It looks like to me that you do as well. I do not have any guesses at this time why you received the warning message.

You have completely removed and reattached both ends of the DP cable to see if that helps, correct?

[BestOrange]

I have.

Frustratingly, it only does it when receiving input from the display-ports on my graphics cards. The motherboard DP port works perfectly noiselessly.

I don't expect it will help this issue, but it shouldn't cause problems to update to the latest amdgpu linux-firmware. Instructions are here.

[BestOrange]

update to the latest amdgpu linux-firmware.

I don't want to call it too soon, but it seems to have worked! The sound is crystal clear!

Ran speech-dispatcher, and it is all good! First time I've been able to get good sound out of my GPU display port since I put the thing together a few months ago.

GPU firmware update seems to be all that was missing! Thank you for suggesting it!

Feel free to mark this as resolved now.
