Pop OS 22.04에서 Logitech 웹캠 C270에 간헐적으로 발생하는 문제 - UVC 카메라(046d:0825)

Pop OS 22.04 및 LMDE 4의 웹캠에 문제가 있는 것 같습니다. Xubuntu 18.04에서 완벽하게 작동하는 동일한 장치가 있습니다.

카메라를 사용하려고 하면 흰색 화면이 나타나는 경우가 cheese많지만 guvcview결국 예상한 이미지가 나타납니다. 캡처된 오디오는 작동하는 것으로 보이지만 Google Meet의 영상 통화에 영향을 미치는 것으로 보입니다. 오디오 수신이 불규칙하고 인터넷 연결에 문제가 있다는 증거가 없습니다.
