내 HP Ultrabook의 트랙패드를 교체해야 했기 때문에 저렴한 198달러짜리 Acer Gateway NE46RS1 노트북을 구입하고 여기에 Linux Mint 18을 설치했습니다. 헤드폰 출력 외에도 이 노트북에는 통합 스피커가 하나만 있습니다.
그래서 나는 alsamixer에서 노트북 스피커의 소리를 들으려면 "헤드폰" 볼륨을 높여야 한다는 것을 발견했습니다. 또한 헤드폰을 연결하면 헤드폰 볼륨을 다시 높이지 않으면 스피커가 음소거되고 음소거 상태가 유지됩니다. 스피커가 작동하려면 믹서에서 헤드폰 볼륨을 높여야 합니다. "sudo alsactl store"를 실행하여 alsa 상태를 저장하려고 시도했지만 다음 재부팅 시 상태가 유지되지 않고 침묵됩니다. 또한 "전면" 볼륨이 누락되었습니다.
내가 원하는 것은 "헤드폰" 볼륨을 사용하는 대신 스피커에 적절한 볼륨 제어 옵션을 다시 할당하고 시작할 때마다 자동으로 음소거하는 대신 볼륨 상태를 저장하는 것입니다.
