Hello:
Yes, I installed Zorin 16 after installing the new motherboard.
No, I have installed Alsamixer , Pulseaudio and Pavucontrol.
Alsamixer I find a bit complicated to handle, unlike Pulseaudio and Pavucontrol.
Regards
True... But Pulseuadio runs complicated, even if Pavucontrol makes the UI easy. What you set in it and what it does may not always be similar...
@alexandros For what it is worth, Alsamixer
from terminal (not the optional Alsamixer GUI install from Software) is my favorite tool for diagnosing and fixing sound problems on Zorin.
Question is, are you able to run Alsamixer
and post a screenshot of the display here?
Hello:
As I mentioned before, I am a user at a very basic level.
This is what I get in relation to Alsamixer.
I have just done a serach for that motherboard to see what audo device it has.
https://www.asus.com/uk/Motherboards-Components/Motherboards/PRIME/PRIME-B450M-A-II/techspec/
i.e.
Realtek ALC887/897 7.1-Channel High Definition Audio CODEC
Your Nvidia GPU is listed as sound card, not the Realtek device.
What does Asamixer display for sound cards when you hit [F6] key?
In addition, can you post results of:
aplay -l
(Note "l" is lowercase L not numeric 1)
Hello:
First of all I thank you for your patience and willingness.
This shows alsamixer when you press F6:
This is what comes out when you press aplay -l:
Thank you very much.
Again run Alsamixer
from terminal.
Again hit [F6] then select "2 HD - Audio Generic" from the drop-down list of sound cards.
What does that then give you on the Alsamixer screen?
Good. That looks more normal to me.
In Alsamixer you can mute/unmute channels by scrolling accross then hit "M".
Does your sound now work as you wish, or do you still have a problem?
If this is fixed, please mark the post that helped you as Solution from the ... post Replay toolbar.
Hello:
Thank you very much for the help.

Hello:
I have a question. Through Alsamixer I can mute HdNvidia, which, apparently, is the card that is giving sound problems. However, every time I turn on the computer I have to perform this action, again.
Is there any way to save these changes permanently?
Thank you very much.
Regards
What do you mean by that? Are you having to go in and select "HD - Audio Generic" as defaut sound card?
I think you can change default sound card under Zorin/Settings/Sound
but am not on ZorinOS to try that myself at the moment. Maybe someone else on here can confirm that? @Aravisian @FrenchPress
After that, lets see what happens when you save that Alsamixer
setting using:
sudo alsactl store
Does that store that choice of sound card after a re-boot?
@Aravisian Nah. I thought Settings/Sound had a way of selecting default sound card. Seems not.
Hello:
I have to report that the proposed solution was not effective. I still have the same problem, when trying to play videos on youtube the sound disappears. Sometimes after watching a few videos, sometimes when trying to play the first one.
When I look at the sound section in settings, only the dummy sound output is visible.
I tried to mute this output using alsamixer, (I had previously tried with pavucontrol), but to no avail.
I am convinced that the problem derives from the new motherboard, since the old one did not have this problem.
In situations like this, it makes me want, for a brief moment, to go back to Windows.
Anyway, I want to reiterate my thanks for taking care of my problem.
Regards.
Re dummy sound. There is a thread on here about that, which may give you some leads, but do not know if a "fix" was found. Dell Precision 5750 - No sound ( Dummy Output )
Dummy Sound is (or was) a common complaint at one time. I think there are many instances on different "Ubuntu" forums that discuss it. Maybe websearch "Dummy sound Ubuntu"
Thank you very much for the suggestion.
Regards
There must be a simple way to change your default sound card. I just did a websearch using "make sound card default" and this came up. It looks similar to your case and the source (it's FOSS) is considered a good one:
Hello:
Thank you very much for the suggestion.
I will see the proposed solution.
Greetings.
