After applying the patch on ubuntu-focal hwe-5.11, the microphone was found, and was producing sound. Though, the quality is like I'm sitting in the bathroom. I have no clue on how it sounds on a Windows PC, so I really have no clue what quality to expect. I fear that there's nothing to do about it, since I've bought it for €10,-.

The webcam behaves just fine, where the microphone outputs noise. Looking at dmesg, the log is spammed with: [ 3657.927446] xhci_hcd 0000:00:14.0: WARN: buffer overrun event for slot 4 ep 4 on endpoint I've applied [this patch](https://mailman.alsa-project.org/pipermail/alsa-devel/2020-December/178361.html) manually on linux-source-5.4.0.tar.bz2 to see if the microphone works after that. Unfortunately the microphone wasn't detected by pulseaudio and I've tried tuning values with guvcview, but to no avail. I'm about to test another patch for this issue. https://www.spinics.net/lists/alsa-devel/msg132769.html ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.11.0-43-generic 5.11.0-43.47~20.04.2 ProcVersionSignature: Ubuntu 5.11.0-43.47~20.04.2-generic 5.11.22 Uname: Linux 5.11.0-43-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: GNOME Date: Sat Dec 18 14:58:51 2021 InstallationDate: Installed on 2020-08-07 (498 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) SourcePackage: linux-signed-hwe-5.11 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.11/+bug/1955304/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
