방금 lenovo U430p를 주문하고 우분투 14.04를 설치했습니다. 오디오를 제외한 모든 것이 매력처럼 작동했습니다. 오디오가 작동하고 시스템에서 감지되지만 Windows 8.1(사전 설치되어 제공)에 비해 소리가 매우 낮습니다.

답변1
- 기본 사운드는 두 번째 사운드(첫 번째 사운드는 hdmi 사운드)이므로 소프트웨어 센터(또는
sudo apt-get install pavucontrol)에서 "펄스 오디오 볼륨 제어"를 설치하고 멀티미디어 메뉴에서 실행하세요. - "출력 장치" 탭으로 이동하여 마지막 장치의 볼륨을 설정하세요.
- 마지막 오른쪽 탭에서 프로필을 변경하면 도움이 될 수 있습니다.
alsamixer터미널에서 볼륨 실행을 설정한 다음 F6을 눌러 두 번째 카드를 선택하고 오른쪽/왼쪽 화살표를 눌러 페이더를 선택하고 위쪽/아래쪽 화살표를 눌러 볼륨을 설정하고 m 키를 눌러 음소거/음소거를 해제할 수도 있습니다 .
