我在 Ubuntu 15.04 上使用 S/PDIF 和 HDMI 音訊時遇到問題。
「系統設定 > 聲音」中顯示 S/PDIF 輸出，但沒有聲音輸出。 HDMI 輸出不顯示。
我嘗試執行步驟 1 中的命令https://help.ubuntu.com/community/SoundTroubleshootingProcedure，但他們並沒有解決問題。
以下是 alsa-info.sh 腳本的輸出：http://www.alsa-project.org/db/?f=76f5134bf711a2727fa56d1d7ec582945fc6944c
這是輸出aplay -l：

當我跑步時aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav，我得到
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
然而，實際上沒有聲音播放。卡 0 的設備 7 和 8 以及卡 1 的設備 1 也會發生同樣的情況。
有什麼想法我可以從這裡去哪裡嗎？
