USB 마이크가 있는지 확실하지 않습니다. 다른 매개변수를 몇 가지 시도했는데 마지막에 나타나는 것 같습니다.

답변1

다음 입력 소스 중 하나를 전면 마이크로 설정해야 합니다.

Simple mixer control 'Input Source',0
  Capabilities: cenum
  Items: 'Front Mic' 'Rear Mic' 'Line'
  Item0: 'Line'
Simple mixer control 'Input Source',1
  Capabilities: cenum
  Items: 'Front Mic' 'Rear Mic' 'Line'
  Item0: 'Line'

다음과 같은 것이 귀하의 요구에 적합할 수 있습니다.여기

예를 들어amixer cset name='Input Source',index=0 'Front Mic'

그것은 당신에게 효과가 있을 것입니다.

답변2

Audacity를 실행하고 "기본 설정" --> "장치" --> "녹음"을 선택하고 "장치 펄스: 내부 마이크 0"을 선택하세요.
