Status changed to 'Confirmed' because the bug affects multiple users.

[Harald Franzen (harald-franzen-lotcavediving)]

I can confirm this bug on Ubuntu 16.04 Xenial Xerus, same sound card:

[/quote]

Card is correctly detected, but no sound.

Additional information: THe L521x shows an Nvidia Audio device - It has an Nvidia Physx GT640M Graphics card, I'm guessing its related to that.

Hi,

This sounds similar to my bug.

I am pretty sure my physical speakers work, and even that they worked when I first installed Ubuntu Mate 22.04, but very shortly afterwards they stopped working.

The headphone jack also doesn't work. I installed a jack-detection repo and now sometimes (not constantly) the headphones will shoot out max volume white noise.

Here is my Alsa info: http://alsa-project.org/db/?f=608937f066095ec6710e5f3bafc292815da99414

I've been trying to fix this problem for a couple weeks now. I've followed different blogs on similar topics and read through various solutions to similar problems posted on launchpad or stackoverflow.

Any help would be greatly appreciated.

Re:^^^ Oh, and I have the soundcard: Realtek ALC269VB Analog, also.

[William Z Chadwick (cardioleo)]

Huh, interesting. When I hover my cursor over the sound widgit in my top panel bar, it says:

Output: 100%
0.00 dB
Built-in Audio Analog Stereo

And it says this even when I have something playing that ought to be outputting sound.

Doesn't 0.00 db mean silence?

Reading this now to find out what I can: https://sound.stackexchange.com/questions/25529/what-is-0-db-in-digital-audio -- "So audio meters don't show the dBu, dBV or dBFS level of the signal (some do, but as an extra). Instead they show 0dB as the standard operating level of the system." Oddly fascinating read. I had no idea that decibels were coined in relation to Bell labs.
