I've got sound issues...

[IceyGuide]

So, yesterday I downloaded Linux mint as a Newbie. There was nothing to complain about really. As I started playing some sort of audio or watch videos there was a crackling noise coming out my Headset speakers. Note that I'm not on a Laptop, pulseaudio -k did not fix it nor did anything related to power saving fix it. I've tried so many things but none worked, even reinstalled it again.
Version: Linux mint 20 "Ulayana"
I've noticed that my built-in Audio is doing some weird stuff in pavucontrol I tried to disable it, but it turned back on. Even pavucontrol is Establishing connection to pulseaudio every now and again....
I'm out of Ideas at that point

Hi IceyGuide, and welcome to the forum.

Try this:

If you're experiencing glitches, skips, pops or crackling in your audio playback, it's quite possibly caused by the timer-based scheduling pulseaudio now uses. Disable timer-based scheduling this way:
Users of 18.3 and earlier versions of Mint type this in the terminal: gksudo xed /etc/pulse/default.pa
Users of 19 and later versions of Mint type this in the terminal: xed admin:///etc/pulse/default.pa
Find the line that says load-module module-udev-detect and change it to load-module module-udev-detect tsched=0
Save the file, then run pulseaudio -k in the terminal and test your sound

For the Establishing connection part, when that's happening run this and post the output:

Code: Select all

sudo fuser -v /dev/snd/*

[IceyGuide]

Thanks for your lovely response MrEen, I already tried the tsched=0 method that did not work for me... Any other ideas. Thanks in regards.

[MrEen]

Let's get a look at your full sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info.

[IceyGuide]

should I post the whole stuff in here?

[MrEen]

should I post the whole stuff in here?

Just the URL is fine. If you're concerned about any of the info, you can send it to me in a PM if you wish.

[IceyGuide]

It's fine here you go

Is the "Razer Electra V2 USB" your headset? If so, we can see if changing the profile to Digital improves things. That can be done on the Configuration tab of pavucontrol, or in the terminal with this command:

Code: Select all

pacmd set-card-profile alsa_card.usb-Razer_Razer_Electra_V2_USB_AC1929D06801102-00 output:iec958-stereo

I'm still looking to see if there are other things that might help.

[IceyGuide]

It sadly did not fix it, and yea the Razer Electra is my Headset.

[MrEen]

Okay, I didn't see anything else unusual in the output.

Install (if necessary) and run PulseAudio Volume Control (pavucontrol) and on the Configuration tab set the other audio devices to Off to see if one of them is causing this issue.

If no luck with that, try deleting the files in /home/YourUserName/.config/pulse then running pulseaudio -k in the terminal clears this up.

[MrEen]

And if you're still have issues, try altering the sample rates. In the terminal run xed admin:///etc/pulse/daemon.conf and when the file opens find this section:

Code: Select all

; default-sample-rate = 44100
; alternate-sample-rate = 48000

Try both of these changes:

Code: Select all

default-sample-rate = 44100
alternate-sample-rate = 44100

Code: Select all

default-sample-rate = 48000
alternate-sample-rate = 48000

Reboot after each change and test the sound. Notice the beginning of each line was changed as well as the number.

[IceyGuide]

Thanks again for your ideas, as mentioned earlier the built-in audio is doing some "weird" stuff... I can't turn it off either.

[MrEen]

We can try the drastic method:

Code: Select all

sudo modprobe -r snd-hda-intel

That will unload the driver your built-in card and the HDMI card uses.

[IceyGuide]

It says the following :

libkmod: ERROR ../libkmod/libkmod-config.c:656 kmod_config_parse: /etc/modprobe.d/alsa-base.conf line 44: ignoring bad line starting with 'xed'
modprobe: FATAL: Module snd_hda_intel is in use.

[MrEen]

Well that's a weird looking error. Let's see the output of cat /etc/modprobe.d/alsa-base.conf

[IceyGuide]

And there it goes :

[MrEen]

Okay, either manually remove the last line in that file, or use this command once only to do it:

Code: Select all

sudo sed -i '$ d' /etc/modprobe.d/alsa-base.conf

Reboot after that and see where things stand.

[IceyGuide]

Nothing changed still the same problem as before....
So notice that there's a static / crackling noise while entering the login screen + logging in (on the login sound), and while playing back videos and/or playing games with audio

[MrEen]

Did you try the sample rate changes?

[IceyGuide]

Yea, both of them increased it!

NOTE : I didn't have that static / crackling noise in Windows 10
