Dell XPS 17 9700 internal microphone issue

jp flag

Dell XPS 17 9700
BIOS version: 1.7.2
OS version: 20.04.2 LTS
Kernel: 5.10.0-1029-oem --> linux-oem-20.04b package.

I had an audio issue with Dell XPS 17 9700. I found the solution on dell forum 2nd post: https://www.dell.com/community/XPS/DELL-XPS-17-9700-Ubuntu-Debian-Linux/td-p/7861072

Sound is back after kernel actualization from linux-oem-20.04b package. Internal microphone still doesn't work. It apears in audio settings (Mic in OS settings). But there is no input. I tried to set various Alsamixer settings but with no success. I turned audio off and on in BIOS but it's not a solution.

I have also some ACPI error messages. As a Linux newbie I have no idea how to investigate them.

  • Is any kernel package tested with XPS 17?
  • What could I check to investigate the problem?
  • My temporary solution is to use bluetooth mic.

Could you [edit] your question to explain what you mean by “There are a lot of issues”? What specific problems are you seeing? Which kernel are *you* running? This will make it much easier to provide possible solutions without guessing wrong and wasting everyone’s time …

FYI, there is a [forum](https://www.dell.com/community/Linux-Developer-Systems/bd-p/a-4613-en-forums) on Dell's web site for Linux users. You can consider asking there as well.

There is solution which works out of the box with 5.11.0-27-generic kernel and newer. Simply use command below to install it.

sudo apt install linux-generic-hwe-20.04

I experienced the same issue after an upgrade to the 5.10.0-1029-oem kernel. Now I am on version 5.10.0-1051-oem and I fixed the Issue by switching the rt715 ADC 24 Mux selector in alsamixer to DMIC3.

Press F6 to select the sof-soundwire soundcard

Set rt715 ADC 24 Mux to DMIC3

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.
