Headset microphone not working while internal built-in microphone works in Dell inspiron 5759 running Ubuntu 20.04.3 LTS

cn flag

I have a Dell Inspiron 5759 laptop running Ubuntu 20.04.3 LTS. My laptop's internal in-built speakers and microphone works well. But when I plug in my headset(3.5 mm 4-pole [TRRS]), headset output audio works fine, but headset microphone is not working.

Sound settings

As you can see in my sound setting, where there is some response in headset microphone, but it's actually a static noise when I tried to record it.

Please find my ALSA Information Script in case you find it useful to help.

Also find the output for the command lspci -knn | grep -i audio -A2

lspci -knn | grep -i audio -A2

And output for the command cat /proc/asound/card*/codec* | grep Codec

cat /proc/asound/card*/codec* | grep Codec

PS: I'm new to Linux and this microphone issue drives me crazy. I tried a lot of solution and finally came here for help. Thanks in advance!

How is the headset attached. USB Bluetooth 3.5 jack?

Hi @David. It's attached using 3.5 jack.

A single jack or 2? If it uses only one then it needs an adapter to be able to use both ports on the laptop to use sound and mic.

It's a single jack. As mentioned in my laptop specs, "One headset (headphone and microphone combo) port". My headset contains an in-built microphone. Do I still need an adapter?

So you need the adapter so it plugs into both sound and mic on the laptop. Sounds like you are using a headset made for a phone.

Could you provide a link to an adapter as I have limited knowledge on that?

Right now, the headset microphone is working, and it turned out to be a hardware issue in my laptop's IO board. I disassembled my laptop and cleaned my IO board, and my microphone issue is solved. Thank you!

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.
