Internal Microphone does not work.[SolvED]

Post by Batson »

I recently installed LM20 on a new Dell Inspiron 15 -5575 laptop which has the AMD Ryzen 7 / Radeon Vega chipset.

The Mic has never worked on LM20... It appears in the audio controls as "Internal Microphone Family 17h (Models 10h-1fh) HD
Audio Controller". All the controls for it are muted and unresponsive.

One of the people here suggested that I try running the following command:

Here are the results:
kenji@BirdBrain:~$ curl https://gitlab.freedesktop.org/pulseaud ... line=false | bash | nc termbin.com 9999​
nc: port number invalid: 9999​

Hi Batson,

Houston, we have a problem. From your output:

Code: Select all

nc: port number invalid: 9999​
I've never seen that before. Just to be safe, I just ran the command and it worked properly for me:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  2039  100  2039    0     0    710      0  0:00:02  0:00:02 --:--:--   709

Make sure the line is structured properly, as the email might have truncated something:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

If the above still fails, try this script instead:

Code: Select all

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh
The script should ask if you want to save locally, or upload. Please choose upload and paste the link it'll give you.

This one is the second half of what the other one should have produced. And could be the part that is needed anyway.

For starters, the card is set for output only. This will change that:

Code: Select all

pacmd set-card-profile alsa_card.pci-0000_04_00.6 output:analog-stereo+input:analog-stereo
Test after running that, checking to see if it's still muted and volumeless.

I'm heading to bed now, but will check on progress tomorrow.

Voila! The Mic works...

Thank you very much, I would have never figured that out.

LM20 is great when it works like it should but most certainly a Mystery to Newbies when it does not.

I'm patiently waiting for the developers to come up with some working video drivers for the AMD Ryzen/Radeon CPU/GPU processors.

Aloha
