Hi, I also had the issue of a IPU6 camera of a Dell Latitude stopped working in 6.14.0-27 I tried a lot and got it working, unsure which of my steps were needed in the end.
The last one I needed to fix was permission issues, e.g. userspace. Please check the following as root, and then as normal user: `gst-launch-1.0 icamerasrc ! autovideosink` For me it worked as root (after sudo bash), but not as normal user. After changing permissions to `crw-rw---- 1 root render 510, 0 Aug 1 17:21 /dev/ipu-psys0` by adding a udev rule: ``` cat /etc/udev/rules.d/99-ipu6-permissions.rules KERNEL=="ipu-psys0", MODE="0660", GROUP="render" ``` things also worked for the normal user.

Then linux-generic-hwe-24.04 was updated to 6.11 and with the linux-modules-ipu6-generic-hwe-24.04 package the webcam and sound started working (although the headphone jack didn't). We did occasionally have issues where we needed to kill the v4l2-relayd. Recently, linux-generic-hwe-24.04 has been updated to 6.14 and now the webcam no longer works at all, although the sound does still work.
