サウンド設定が保存されていません

ここ は何が起こっているかを示すビデオです。

入力を「リアマイク」に設定するたびに、「デジタル入力（S/PDIF）」に戻ります（ウィンドウを閉じるだけで、再起動もログアウトもしません）。これは、出力が正常に機能するため、入力タブでのみ発生します。 pactl list sourcesを実行すると、ウィンドウを開いたときに次のようになります。

私はオーディオに問題があったので、これらのコマンドを実行しましたが、おそらく何かを台無しにしました：

Sudo apt-get install alsa-tools-gui
Sudo apt-get remove pulseaudio
Sudo apt-get remove pulseaudio-utils
Sudo apt-get remove pavucontrol
Sudo apt-get install pulseaudio
Sudo apt-get install pulseaudio-utils

ここでは、サウンドインジケータといくつかのシステム設定がなくなったため、次のことを行う必要がありました。

Sudo apt-get install indicator-sound
Sudo apt-get install unity-control-center
sound14.04microphonesystem-settings

私はそれを修正する方法を見つけました：pavucontrolを再インストールしましたが、リアマイクがそこに表示されなかったので、サウンド設定を変更し、今ではpavucontrolにも表示されて動作します。唯一の問題：サウンド設定を再度開くと、デジタル入力が表示されますが、それは問題ではありません。ありがとうございました！
