Ubuntu 20.04-音が出ない

Ubuntu 20.04 LTSをインストールしましたが、音が聞こえず、Lenovo Legion Y520-15IKBNを使用しています。 Ubuntuを使い続けてLinuxについて学びたいのですが、音が聞こえないのは一種の取引ブレーカーであり、Windowsに戻ることが最後の手段です。

私はすべてのGoogleの結果とすべての「解決策」を試しましたが、何も機能しません。このようなスレッドがすでに存在している場合もお詫びしますが、Ubuntuに質問を探していて、解決策を見つけることができませんでした。

あなたの助けをありがとう、そして私の英語でごめんなさい:)

まず、USBヘッドフォンを接続すると、オーディオは問題なく動作しますが、問題はラップトップの内蔵スピーカーとマイクにあります。

これが私が知っていることです：

virtualboxの下で実行している場合：20.04をVMに新しくロードしました。驚いたことに、音量はデフォルトでミュート（0％）に設定されています。設定を開く->サウンドと「音量レベル」（システムサウンド）で音量を上げるという単純なプロセスでこれを解決しました（以下に示すデフォルト設定）

同じ問題がありました。 Ubuntuの横にUbuntu 20.04をインストールした後、音が出ないことに気付きました。 alsa-baseとpulseaudioを再インストールすると解決しました...

Sudo apt-get install --reinstall alsa-base pulseaudio
Sudo alsa force-reload

pavucontrolで運がよかった。何らかの理由で、[設定]-> [サウンド]ダイアログボックスの出力セレクターが機能しませんでしたが、pavucontrolを使用すると、正しい出力を選択できました。

$ Sudo apt install pavucontrol
