마이크 입력 없음 - VIZIO CT15-A5 및 12.04 LTS (64)

내 VIZIO CT15-A5 및 12.04 LTS(64)가 원활하게 실행되고 있습니다.. 한 가지 문제가 있습니다.. 마이크 입력이 누락되어 사운드를 녹음하거나 Skype를 사용할 수 없습니다.

알사 믹서를 사용해 소리를 키워보고, 펄스 오디오 볼륨 조절도 사용해 봤는데, 하드웨어 문제가 있는 것 같습니다..윈도우(듀얼부팅 시스템)에서는 잘 작동합니다.

이것이 출력이다lspci -vv

또한 "/etc/modprobe.d/alsa-base.conf"에 다음을 추가하려고 시도했지만 소용이 없었습니다.

options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes

네, 이상한 전면 오른쪽 채널 비활성화도 시도했지만 성공하지 못했습니다.

여기 내 원본 alsa-base.conf의 복사본이 있습니다.
