고통 없이 마이크와 라인을 동시에 녹음하는 가장 쉬운 방법은 무엇일까요?

저는 alsa, pulseaudio, pavucontrol, jack 등과 함께 Arch Linux를 사용하고 있습니다. 볼륨이 아무리 낮아도 마이크와 기타 소리를 동시에 녹음하고 싶습니다. 두 개의 채널이 한 채널의 후면 마이크에 연결되고 다른 채널의 라인 입력이 모니터 또는 연결 잭 수신기에 연결된 가상 펄스 오디오 수신기를 만드는 방법에 대한 여러 기사가 있지만 제 경우에는 아무 의미가 없습니다. 현재 설정.

그러나 이것은 스크립트에 있습니다.

$ pactl list short sources

 1  alsa_input.pci-0000_00_1b.0.analog-stereo   module-alsa-card.c  s16le 2ch 44100Hz   RUNNING

하지만 나에게 필요한 것은 이것이다.

$ pactl list sources|grep input
Name: alsa_input.pci-0000_00_1b.0.analog-stereo
    analog-input-front-mic: Front Microphone (priority: 8500, not   available)
    analog-input-rear-mic: Rear Microphone (priority: 8200, not available)
    analog-input-linein: En línea (priority: 8100, not available)
Puerto Activo: analog-input-front-mic

장치가 아니라 포트입니다. 레코드의 출력은 다음과 같습니다

 $ arecord -l
 **** List of CAPTURE Hardware Devices ****
 card 0: Intel [HDA Intel], device 0: VT1708B 8-Ch Analog [VT1708B 8-Ch Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

그렇다면 alsa 또는 pulseaudio를 통해 이러한 포트에 어떻게 액세스합니까? 아니면 다음과 같은 보다 간단한 솔루션이 있어야 합니다.

$ arecord 1 channel1.wav&arecord 2 channel2.wav
