[SOLVED] Not detecting the soundcard

mickee384 · 07-27-2020, 08:36 PM

I have posted some of this in another group, but I need some help with the BIOS on my laptop. Its American Megatrends. I have no problem getting in there, but there is basically nothing on the Advanced tab. I am trying to get in contact with the maker to see if they locked some settings down. This is the model: Mytrix LinuxBook 7350, 13.3" Full HD Slim Laptop, i5-8250U Quad-Core up to 3.40 GHz, 8GB RAM, 1TB PCIe NVMe SSD, USB-C/DP, HDMI, Backlit KB, FP Reader, Webcam, Metal Body Design, Ubuntu Linux

Series Mytrix KN13-7350

Have any of you heard of this type? I bought it on Amazon. There are no real specs on the onboard audio - but its not being detected at all from inside Ubuntu. Also sound properties display Dummy Output. This is why I want to look in the BIOS. I believe its an "hda intel" but at this point I am unsure. Any help is appreciated!

Hi,

Welcome to LQ!

I do not use Ubuntu but you could use from the command line in a virtual terminal as root;

Code:

lspci -vv |grep -i Audio
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
        Subsystem: Dell 6 Series/C200 Series Chipset Family High Definition Audio Controller

As you can see my laptop uses a Intel chip set.
This way you will know what is being used by the system. If you look at the full output for 'lspci -vv' you will see all the data relative to your system.
Hope this helps.
Have fun & enjoy Gnu/Linux!

Thanks for your help! I was not successful in th exact command so I ran

Code:

sudo lspci

and got this output:

Code:

brian@mickeelaptop:~$ sudo grep -e|lspci
grep: option requires an argument -- 'e'

there is no mention of audio at all anymore. I'm hoping that the maker of my laptop can provide me with drivers if they are special.... or let me know how to get into the Advanced Settings in the BIOS. I was told to disable on board sound, boot up restart and enable in BIOS again, but there is nothing in advanced. By the way the sound worked when I got the laptop but stopped working when I changed Desktop environments from from gdm3 to lightdm and back to GDM3. That is when the sound stopped...

Even when no driver is loaded, the audio card should be enumerated in the output. Perhaps try shutting the PC laptop down completely, leave disconnected from the mains, and perphaps remove the battery for a few mins. Then reinstate and boot up again. Does this return the card?

Code:

lspci -nnk|grep -i audio

I stand corrected. All sound seems to be working! Awesome! Lets see if it stays after a reboot.

Good to know. I actually meant to specify

Code:

lspci -nnk|grep -iA3 audio

This would show enough lines to have confirmed driver loaded. In any case good to know that your sound is now working!

it even stayed after a reboot. Thanks so much for your help!

You're welcome.
