블루투스 스피커가 연결되어 있지만 음악이 재생되지 않습니다

Beoplay P2 Bluetooth 스피커를 Ubuntu/KDE 노트북과 함께 사용할 수 있게 되기 직전인 것 같습니다.

모든 Bluetooth 유틸리티는 스피커가 연결되어 있음에 동의합니다. 예를 들어 bluetoothctl시작 출력에는 다음이 포함됩니다.

    [NEW] Device 04:FE:A1:4B:0F:EA Fenchurch

스피커 장비입니다. (그것이 바로 이라고 합니다 Fenchurch.) 더 자세한 내용을 물었을 때 얻은 결과는 타당해 보였습니다.

KDE Bluetooth 구성에서는 스피커가 연결되었다고 주장하며 스피커 자체에 동의함을 나타내는 표시등이 있습니다.

장치가 플라즈마 오디오 볼륨 위젯에 나타납니다.

다음에도 나타납니다 pavuctl.

더욱 매력적인 점은 볼륨을 조절하면 pavuctl스피커 자체에서 확인음이 나온다는 점이에요! 하지만 내가 재생할 수 있는 유일한 소리입니다.

예상대로 소리는 노트북에 내장된 스피커에서 나왔습니다.

무엇을 조사해야 합니까? 다음에는 무엇을 합니까?

추가 정보 또는 붉은 청어:

• 내 전화기는 스피커에 연결하고 재생하는 데 아무런 문제가 없었습니다.
• 실제로 노트북과 휴대폰에서 Spotify를 열면 Spotify는 연결된 Bluetooth 스피커에서 음악을 재생하도록 휴대폰에 지시할 수 있습니다!
• 스피커가 노트북에 연결되어 있는지 확인하기 위해 휴대폰의 Bluetooth 연결을 비활성화하면 흰색 표시등 대신 녹색 표시등이 표시됩니다. 이는 "핸즈프리" 모드에 있음을 의미합니다. 일반 스피커와 어떻게 다른지는 잘 모르겠습니다.

alsamixer사운드카드가 1개만 있다고 하더군요. 다음과 같습니다.

정확한 이름을 입력하면 P2를 인식하게 할 수 있는데 이름을 찾는 방법을 모르겠습니다.

다음 요청에 따른 출력은 다음과 같습니다 systemctl status bluetooth.
