Logitech H800 헤드폰의 마이크가 "HFP/CVSD" 8kHz보다 더 나은 품질로 작동하도록 할 수 없습니다. 이것이 본질적인 하드웨어 문제인지 구성 문제인지 알아보고 싶습니다.
Ubuntu 22.04에서 파이프라인/와이어 배관공을 사용하고 있습니다.

보시다시피 a2dp-sink-faststream_duplex명령문은 다음과 같습니다. sinks: 1, sources: 0. 그러나 아래에서는 입력과 출력이 모두 구성 파일의 일부 ports라고 말합니다 .a2dp-sink-faststream_duplex

input/microphone/source 임에도 불구하고 표시되기 때문에 이상해 보입니다 profile = "a2dp-sink".
이 문제를 해결하기 위해 할 수 있는 일이 있습니까? 아니면 이 헤드셋을 HFP/CVSD "기본 전화기" 모드에서 사용할 수 없습니까?
