Ubuntu 15.04 で S/PDIF および HDMI オーディオが動作しない問題が発生しています。
「システム設定 > サウンド」に S/PDIF 出力が表示されますが、サウンドは出力されません。HDMI 出力は表示されません。
ステップ1のコマンドを実行してみましたhttps://help.ubuntu.com/community/サウンドのトラブルシューティング手順しかし、問題は解決されません。
alsa-info.sh スクリプトの出力は次のとおりです。http://www.alsa-project.org/db/?f=76f5134bf711a2727fa56d1d7ec582945fc6944c
出力は次のとおりですaplay -l:

走るaplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wavと
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
ただし、実際にはサウンドは再生されません。カード 0 のデバイス 7 と 8、およびカード 1 のデバイス 1 でも同じことが起こります。
ここからどこへ行けばよいか、何かアイデアはありますか?
