두 개의 헤드폰을 통해 비디오를 들으려고 합니다. 하나는 블루투스로 연결되고 다른 하나는 케이블로 연결됩니다.
두 옵션 모두 개별적으로 작동하지만 함께 작동하도록 할 수는 없습니다.
다음 명령을 사용하고 있습니다.
$ pacmd load-module module-combine-sink \
sink_name=combined5 \
slaves=alsa_output.pci-0000_00_1b.0.analog-stereo,bluez_sink.70_26_05_89_B1_2F.a2dp_sink \
sink_properties=device.description=myCombine5 \
pacmd set-default-sink combined5
설정을 확인하기 위해 및 을 사용하여 mplayer새 vlc수신기가 실제로 와 작동하는지 확인했습니다 pavucontrol.
놀랍게도 새 수신기의 출력은 케이블을 통해 연결된 헤드폰으로만 전달됩니다. 블루투스 헤드셋이 조용했습니다. 재부팅 pulseaudio하고 -v로그 출력을 살펴봤지만 오류를 찾을 수 없습니다.
내가 할 수 있거나 확인할 수 있는 다른 아이디어가 있나요?
편집: pacmd list-sinks의 출력을 추가했습니다.
$ pacmd list-sinks

편집: 댓글에서 언급했듯이 블루투스 헤드폰만 포함된 콤보 수신기를 추가했습니다. 나는 Paplay로 트랙을 재생한 다음 해당 소스의 pacmd list-sink 출력을 일반 Bluetooth 수신기의 출력과 비교했습니다. 아래에는 변경된 줄의 출력이 표시됩니다.
