This is a fesh installation on a HP Elitebook 840-G3.

Operating System: Kubuntu 20.04
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8
Kernel Version: 5.11.0-41-generic
OS Type: 64-bit
Processors: 4 × Intel® Core™ i5-6300U CPU @ 2.40GHz
Memory: 15.5 GiB of RAM

There is no audio device detected.

I am complete newbie and really don't know what I'm doing here, but I'm following all the suggestions I can find searching this fault It looks like the driver and the device are not meeting up. I know the device works under windows so I'm pretty sure the hardware is not at fault. Here's some of what I have tried...

lspci -nnk | grep -A3 Audio returns nothing

lsmod | grep snd_hda_intel returns nothing

sudo apt purge timidity-daemon reports timidity not installed

sudo apt-get install --reinstall alsa-base pulseaudio makes no difference

sudo alsa force-reload This one gives some information: Unloading ALSA sound driver modules -NONE LOADED- then it says Loading ALSA...(None to reload)

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils worked, then reload

sudo apt-get install linux-sound-base alsa-base alsa-utils

FINALLY got this: inxi -SMA

Welcome to Ask Ubuntu. As Nmath says, we’ll need some more information. Have a look at the help pages to get started:

I have tried to fix the formatting in your post to get rid of the ambiguities caused by lack of formatting and no line breaks. In the future please format commands in `monospace` and when you give the output of commands, **always** copy/paste the entire output verbatim and format it with [code fences]( When you translate terminal output in your own words or only post bits and pieces, this leaves out essential info. Similarly, when there is no formatting (not even line breaks), we can't tell apart commands and output from surrounding text.

Once I learned that ALSA job is to detect the sound card. No card. well ok then. BIOS. that's embarrassing....

Alsamixer works great now the audio device is enabled.

Is the problem solved? If so, thanks for your contribution. Would you mind [cleaning up your answer]( a bit and telling us **exactly** what you did to solve the problem? The solution here isn't very clear. If you can write out step-by-step what is needed to resolve your problem, it would be most helpful for future visitors. Our goal on Ask Ubuntu is to have a library of questions and answers about Ubuntu. Maybe you can help someone else who has the same problem later.

Thank you for guidance, I'm new to this. Once I learned enough to realize that ALSA is the software module responsible for detechting the hardware, I found the command INXA -SMA indicated no hardware. From there I went to the BIOS and found the device was disabled. Enabling the device in the BIOS and then updating Kubuntu, problem solved.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
