libasound2 not working after update

Hi [member=7109]Moltke[/member] ,
I will try these in a few days, we have experienced a covid case at work and I can not go to the office right now.
I will contact you as soon as I can go back to work, I hope it will be soon. Fortunately, I am all right and so my colleagues.

Regards

Sure, no problem. Glad you're Ok, take care. By the way, I see you're from Argentina? You can also post in the Spanish sub-forum https://dfgkh547-jsdfv8.iyhkj.tk/forums/spanish/

The ouptput of the pactl info command is the following_

Where could be any problem?

Saw thread was marked solved and was curious... but it's not :-S

Got two ideas :
1. Try to install the Hardware Enablement pack.
2. Turning off the audio card in BIOS, booting once, then turning back on and rebooting. Pretty sure this procedure would be useless but... trying stuff in Linux

[j8a]

Hi [member=6733]TheDead[/member],
I unmark the post now, I though it will have no responses but [member=7109]Moltke[/member] asked me a question about this and now you too.
I installed HWE support and the output from the terminal command line is the following:

hwe-support-status --verbose
Your Hardware Enablement Stack (HWE) is supported until abril 2025

I rebooted and disabled the sound from the BIOS. Afterwards, I reboot and enabled it.
In both cases the sound is still missing, the output I wrote are the same.  It is a weird problem.

The only thing is changed is that now, the output of pactl info is the following.

Regards,

According to pactl info pulseaudio is enabled and up, which means you should be getting sound, aren't you? If you don't, try renaming your ~/.asoundrc to ~/.asoundrc.bak, restart pulseaudio

Code:

pulseaudio --check

returns 0 when the pulseaudio daemon is already running, or non-zero otherwise. Then

Code:

pulseaudio --start

start pulseaudio if it is not running yet. Implies --daemonize. For more info read man pulseaudio

Hi [member=7109]Moltke[/member] ,
I tried both commands and I recieved no output  on the console. I also move the .asoundrc to .asoundr.bak and restart pulseaudio, but still not sound.

Then, I open a terminal command while I was playing a sound track on VLC and I excecuted the following commands:

I'm quite not sure, because you didn't use BBcode and read all that is a bit messy, but it seems that the audio device might be not the right one, make sure that pulse is using the right device. If you've set this via configuration files, undo that, reboot and let pulseaudio to choose the audio device to use.

[TheDead]

I think Moltke could be on to something...

Then last :
sysdefault:CARD=NVidia
    HDA NVidia, ALC887-VD Analog

Refering the the Widnows world, sound output goes trough different "channels/outputs" so the chipset and output could display differently.
But from in all I see
HDA Generic, Realtek, Intel then nVidia.

Maybe the output tries to go to a USB device (webcam, headphone, cellular, mp3 player, illuminating rock ).
Point 3. mentions a webcam (?), so I would disconnect it and anything USB other than mouse and keyboard if possible and reboot.

I'm still a Linux noob so I can't "decode" all those logs myself. Maybe it's time to boot a live Linux USB key and check with that.
