Public bug reported:
The integrated "HP Wide Vision HD Camera" (USB Vendor ID 0408, Product
ID 5481) on an HP Victus by HP Gaming Laptop 15-fa0xxx is experiencing
significant issues with video conferencing applications (specifically
Google Meet and Zoom) on Ubuntu 24.04. The camera is often not detected,
or the video feed is unstable, frequently cutting out with no clear
error messages in standard system logs.
Restarting the pipewire.service (user-level) sometimes temporarily
resolves the "no camera" issue, allowing the camera to be used. However,
the video quality is often limited to very low resolutions (e.g., 180p),
and even at these low resolutions, the video can be choppy or exhibit
intermittent issues. Attempting to use higher resolutions consistently
leads to the video feed cutting out entirely.
Kernel logs (journalctl -k -f | grep uvcvideo) show "Failed to resubmit
video URB (-19)" errors, indicating a problem with USB communication to
the webcam.
Troubleshooting steps taken include:
Trying various uvcvideo quirks via modprobe and /etc/modprobe.d/uvcvideo.conf.
The quirk options uvcvideo quirks=0x00000080 (UVC_QUIRK_FIX_BANDWIDTH) seems to
provide the most stable experience, allowing video at very low resolutions
(180p) in both Google Meet and Zoom, although Zoom is choppier. Higher
resolutions remain unusable.
Investigating USB power management using powertop, which showed the webcam's
autosuspend was already set to "Good."
Restarting the pipewire service.
Testing with a command-line webcam application (snapshot), which also crashed.
Checking pipewire logs (journalctl -u pipewire.service), which showed errors
related to VIDIOC_STREAMON, VIDIOC_STREAMOFF, and VIDIOC_REQBUFS with "No such
device" errors for /dev/video1.
The issue was also present in a Timeshift restore to Ubuntu 22.04 from a point
where the camera was previously working, suggesting a potential regression or
persistent configuration issue. The problem started around April 19, 2025.
