次のコマンドを実行して、オーディオが機能していることを確認しようとしました。
~のためoutput:hdmi-stereo
aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Right.wav
- 音声なし
~のためoutput:analog-stereo
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Right.wav
- オーディオが存在します
これは私のものです。pactl list short sinks
0 alsa_output.pci-0000_00_0e.0.analog-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
したがって、デフォルトはシミュレートされたステレオであることがわかります。だから、次のように変更しました。
pactl set-card-profile 0 output:hdmi-stereo
pactl set-default-sink alsa_output.pci-0000_00_0e.0.hdmi-stereo
pactl list short sinksそれは
1 alsa_output.pci-0000_00_0e.0.hdmi-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
次のコマンドを実行すると、両方にオーディオがあります
aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Right.wavoutput:hdmi-stereo- オーディオが存在します
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Right.wavoutput:analog-stereo- オーディオが存在します
output:analog-stereoこの設定でプレイする理由は優先順位が高いからではないかと思います。理想的には、どちらも同じ優先順位で実行したいと思います。これは、私がプレイするために行ったステップに従う必要がないことを意味しますoutput:hdmi-stereo。とにかく両方をプレイする必要があります。一致するように優先順位を変更する必要がありますかoutput:analog-stereo？両方6000か。これをどのように実行しますか？
