PulseAudio 출력 포트에 "아날로그 스테레오"와 "디지털 스테레오(HDMI)"를 동시에 표시하려면 어떻게 해야 합니까?

제목에서 알 수 있듯이 PulseAudio에 내장된 옵션 Analog Stereo과 출력 옵션이 보이지 않습니다 Digital Stereo (HDMI). 구성 탭에서 프로필을 변경하고 및 사이를 전환하면 Analog Stereo Output사운드 Digital Stereo (HDMI 5) Output출력이 예상대로 작동합니다. 그러나 출력 장치 탭에는 하나의 출력 싱크만 표시되므로 PulseAudio 트레이 플러그인은 출력 포트를 변경하는 옵션을 제공하지 않습니다.

여기에 이미지 설명을 입력하세요.

두 개의 오디오 싱크가 포함된 사용자 정의 PulseAudio 프로필을 정의해야 합니까? 연결되면 새 출력 포트가 자동으로 나타나는 다른 설치에서는 이 문제가 표시되지 않습니다. Xubuntu 20.04.1 LTSLG 그램 17에서 사용하고 있습니다 .

미리 감사드립니다!

답변1

아날로그 및 다양한 HDMI 수신기가 동일한 카드에서 나오므로 기본 구성에서는 모두 하나의 프로필로 구성되는 것으로 보이며, 이는 한 번에 하나의 프로필만 사용할 수 있음을 의미합니다. 따라서 이 문제를 해결하려면 사용자 정의 구성 파일이 실제로 필요합니다.

내 경우에는 아래 지침을 따랐습니다.pulseaudio에 구성 파일 쓰기. 저는 2개의 파일을 만들었습니다.

/etc/udev/rules.d/91-pulseaudio-intel.rules

# Custom Profile for onboard Intel 8086:a171

SUBSYSTEM!="sound", GOTO="xpulseaudio_end"
ACTION!="change", GOTO="xpulseaudio_end"
KERNEL!="card*", GOTO="xpulseaudio_end"

SUBSYSTEMS=="pci", ATTRS{vendor}=="0x8086", ATTRS{device}=="0xa171", ENV{PULSE_PROFILE_SET}="intel-hdmi+analog.conf"

LABEL="xpulseaudio_end"

/usr/share/pulseaudio/alsa-mixer/profile-sets/intel-hdmi+analog.conf

[General]
; # Instead of defining all profiles manually, autogenerate
; # them by combining every input mapping with every output mapping
auto-profiles = yes

[Mapping analog-stereo]
device-strings = front:%f
channel-map = left,right
paths-output = analog-output-speaker analog-output-headphones
paths-input = analog-input-internal-mic analog-input-headset-mic
priority = 15

[Mapping hdmi-stereo]
description = Digital Stereo (HDMI)
device-strings = hdmi:%f
paths-output = hdmi-output-0
channel-map = left,right
priority = 9
direction = output

[Profile output:analog-stereo+output:hdmi-stereo+input:analog-stereo]
description = Analog Stereo + Digital Stereo (HDMI) + Analog Stereo Input
output-mappings = analog-stereo hdmi-stereo
input-mappings = analog-stereo

[Profile output:analog-stereo+output:hdmi-stereo]
description = Analog Stereo + Digital Stereo (HDMI)
output-mappings = analog-stereo hdmi-stereo

그렇다면 달려가는 문제입니다.

$ sudo udevadm trigger -ssound
$ pulseaudio -k

이제 싱크대가 분리되었습니다.

아날로그 스테레오와 HDMI-0이 싱크로, 마이크가 소스로 필요합니다. HDMI-5를 언급했으므로 경로 출력에 hdmi-stereo-extra4를 사용하는 것이 좋습니다. 추가 HDMI 싱크가 필요한 경우 해당 매핑을 추가하고, 모든 옵션을 개별적으로 원하는 경우 각 "활성화된" 싱크 및 소스 조합에 대한 구성 파일을 제공하세요.

Ubuntu 20.04의 파일 /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf(또는펄스 오디오 Git 저장소) 복사할 수 있는 다양한 매핑이 있습니다.
