CD를 재생할 때 오래된 CD 플레이어가 작동하는 것처럼 미디어 재생이 끊기는 현상이 발생합니다. 오디오가 약 200-500ms 뒤로 이동할 수 있습니다. 이 동작은 몇 초에서 몇 분까지의 빈도로 발생합니다. Firefox에서 YouTube 비디오 재생, VLC MP4 재생 또는 mplayer WAV 재생과 같은 소스를 사용할 때 이러한 동작이 발생했습니다.흥미롭게도 Vivaldi 브라우저에서 미디어를 재생할 때는 이런 일이 발생하지 않습니다.비발디에서도 그런 일이 일어나는데, 그런 일이 일어나지 않는 40분짜리 무대도 있어요. 또한 오류가 발생했을 때 CPU 로드가 약간 떨어지는 것을 관찰했습니다. 마더보드의 아날로그 오디오 출력을 사용하고 있습니다. 재생은 동일한 하드웨어를 사용하는 Windows에서 훌륭하게 작동합니다.
내 설정에 대한 몇 가지 정보는 다음과 같습니다. 처음에 이 질문을 드린 이후 Fedora에서 openSUSE로 전환했지만 문제가 지속됩니다. 현재 및 이전 설정에서는 현재 openSUSE 저장소 5.2의 최신 안정 버전인 KDE 데스크탑을 사용합니다. 더 많은 정보가 필요하시면 댓글을 남겨주세요.
