다시 시작한 후에는 오디오가 꽤 오랫동안 작동하지 않습니다. 몇 분 후에 스피커에서 펑하는 소리가 들리고 그 소리가 다시 작동할 것이라는 것을 알았습니다. Pulseaudio와 Alsa를 설치했습니다. 왜 지연되나요? 어떻게 해결할 수 있나요?

HDMI 오디오가 아닌 표준 1/4인치 오디오 잭을 사용하고 있습니다.

/etc/modprobe.d/alsa-base.conf생성/수정 기준bdl_pos_adj: hda-intel에 대한 IRQ 타이밍 솔루션 설정
options snd-hda-intel enable=1,1 bdl_pos_adj=-1,32
실제 bdl_pos_adj값이 정확하지 않을 수도 있지만 저에게는 효과가 있었습니다.
