[Solved] Very loud beeping noise when playing audio from built in speakers

[Arufonso]

so i've been using linux mint 20.3 for about half a year now without any problems and recently had to reinstall, so i decided to install linux mint 21 cinnamon as i was already using cinnamon before.
but there was a problem, every few minutes (1 to 3 minutes) audio will turn to a loud beeping noise that only stops when closing or pausing the program playing music or audio. the sound won't decrease in loudness when lowering the volume and sometimes it remains even when all programs have closed for a while
in firefox, every time it happens in youtube, the video also stops. and in the spotify linux client, the song also pauses.
i've already tried every step in Mr eren's guide showcased in viewtopic.php?t=363010 and have been trying to find a solution within forums for 3 weeks to no avail
i tried installing linux mint 20.3 again and the problem is still present (at this point, i've reinstalled linux both 21 and 20.3 numerous times and the loud noise is always present)
however, audio works completely well when playing from my tv connected with an hdmi cable. the problem is still present when using headphones
i've also tried installing different kernels from 5.4, 5.8, 5.11, 5.13 and 5.15 of which only 5.15 recognizes the built in speakers. the other ones only showed a dummy output and required mr eren's guide to have any sound at all
the audio worked before, im all out of ideas and can't seem to find any solutions to related problems
my laptop is an ASUS chromebook c202

If you recognize your problem in this thread:
https://askubuntu.com/questions/1393842 ... -21-10-asu
then executing this command in the terminal possibly fixes it

Code: Select all

wget -qO- https://gist.github.com/heikomat/3fe272431b44b580c933bfb901a92257/raw | bash

As far as I understand it tries to install new audio drivers in the kernel.

hi, thank you very much for replying
i've been testing this command alongside the steps from this guide https://github.com/heikomat/linux/tree/ ... DeqyJnL4po that was shared in the thread but still to no avail, i still hear the beeping sound every few minutes
i tried it both on mint 21 and 20.3

[vimes666]

Did you also produce a pulseaudio log as suggested on that github page under 'Getting a detailed pulseaudio log, for when debugging is necessary"
If so can you share it here?

[vimes666]

Another question, is the system on mains power or on battery when the beep manifests?

no, but i got some time to read a bit further in the thread

Here's github issue on this problem: https://github.com/thesofproject/sof/issues/3868.

To summarize, adding options snd_sof sof_debug=1 to the /etc/modprobe.d/alsa-base.conf should help.

so i kinda brute forced my way to add options snd_sof sof_debug=1 to the file using

Code: Select all

sudo nano /etc/modprobe.d/alsa-base.conf

and it actually solved the issue within both of my mint installations
thank you for leading me to the thread!

[vimes666]

Ok, I am glad its working

[calderico]

Hello, i have the same issue but i'm new to linux and i have no idea how to fix it. I've opened the
sudo nano /etc/modprobe.d/alsa-base.conf
using the terminal, but i don't know where to copy the:
options snd_sof sof_debug=1
I don't know also what to do after copying that, ctrl+0 and save it? or ctrl + t and execute it?
I could use some help. I'm enjoying my linux experience so far, but i really need to use audio .

[karlchen]

Hello, calderico.

Having gone through my own file /etc/modprobe.d/alsa-base.conf, I am sure that you can simply add the line
options snd_sof sof_debug=1 at the end of the file.
Then save and close the editor nano.

I am not quite sure whether it is really required, but if want to make sure that alsa honours the new parameter, reboot.

HTH,
Karl

[calderico]

Thank you all, i have it solved.
