Linux Mintを更新した後、サウンドが機能しなくなり、トレイアイコンを失いました。次に何を試したらよいですか？
サウンドが機能しなくなった...次に何を試したらいいですか？
最近、DellラップトップでLinux Mint（uname -rは4.15.0-99-genericを提供）を更新しました。その後、トレイアイコンと一緒に（ラップトップの内蔵スピーカーを使用して）オーディオを完全に失いました：
キーボードのサウンドボタンを使用して、音量を上げたり下げたり、サウンドをミュートすることができます。
Mp3を再生すると、PulseAudioボリュームコントロールpavucontrolはサウンドが再生されている（小刻みに動く）ことを示しますが、サウンドは再生されません。
見つけた指示に従ってウェブを検索しましたが、解決策はまだ見つかりませんでした。以下に関連すると思われるコマンドの結果を含めます。
PulseAudioを削除するのは難しい
理由はわかりませんが、pulseaudioを削除しようとすると シナモンも削除されます です。例えば。：
becky@becky-Inspiron-5379:~/Downloads$ Sudo apt-get remove pulseaudio
[Sudo] password for becky:

The following packages were automatically installed and are no longer required:
gsettings-ubuntu-schemas liburl-dispatcher1
Use 'Sudo apt autoremove' to remove them.
The following packages will be REMOVED:
cinnamon indicator-sound libcanberra-Pulse pulseaudio
0 to upgrade, 0 to newly install, 4 to remove and 2 not to upgrade.
After this operation, 5,837 kB disk space will be freed.

Abort.
Sudo apt-get install --reinstall pulseaudioを実行すると、pulseaudioが再インストールされますが、何も実行されないようです。
私のコンピュータが言うこと：
pulseaudio --verboseは多くのエラーメッセージを返します。

私は数時間前にまったく同じ問題に遭遇しました。私が解決できる唯一の方法は、古いカーネル（4.15.0-96-genericなど）の1つを再起動するためにgrubを使用することでした。
これはこの新しいカーネルのバグのようです 4.15.0-99-generic 。
私は個人的にこれら 指示 に従って削除することにしました。特に、4.15.0-99-genericに関連付けられているイメージ、カーネル、および署名されていないイメージを削除し、GRUBを更新すると、ようやく通常に戻りました。
