Diamond Multimedia Systems Deviceに注目してください。これは私のビデオカードのサウンドのようです。私のビデオカードはDiamondマルチメディアです。
また、そこには奇妙なNVIDIAデバイスがあります。これは、現在取り外したNVIDIAグラフィックカードの残りか、何らかのオンボードのものでなければなりません。どちらかわからない。
**UPDATE** I disabled my onboard sound via the BIOS settings, and now only 2 cards appear in this list. The NVIDIA one is gone.
$ killall pulseaudio
また、(タスクバー)(時計の横)のサウンドコントロールをクリックして、ボリュームスライダーをドロップダウンできますが、ボリュームが0の場合は無効/グレーになります。

Radeon 7000 Mobileシリーズカードも搭載したHP Envy 15ラップトップでも同じ問題が発生しました。この投稿は、少なくともシステムが実行されるという点での問題の部分的な解決策ですが、すべてのusbサウンドデバイスを無効にします。
/etc/modprobe.d/alsa-base.confで、ファイルの最後に次の行を追加します。
blacklist snd-usb-audio
このソリューションにより、AMDビデオアクセラレーションを搭載したラップトップが、USBサウンドデバイスを搭載しなくても、非常にうまくラップトップを使用できます。より良い解決策は、ドライバーが壊れているように見えるので、AMD Radeonカード上のUSBデバイスを選択的に無効にする方法です。
gnome-sound-appletをアンインストールして再インストールすると役立つ場合があります
ターミナルを開いて入力します
Sudo apt-get install --reinstall gnome-sound-applet
gnome-sound-appletをアンインストールしてから再インストールします。
この同じ問題がありました。次の行を追加して回避しました。
blacklist snd-hda-codec-hdmi
/etc/modprobe.d/alsa-base.conf
。これはuser1798721のソリューションと似ていますが、問題はHDMIサウンドデバイスであり、USBサウンドデバイスではないようです。
もちろん、これはHDMIサウンド出力を無効にします。私の場合、マザーボードのサウンドデバイスからSPDIFデジタル経由でサウンドシステムにサウンドを出力し、ビデオにはHDMIのみを使用しているため、損失はありません。しかし、これを修正することは素晴らしいことです。古いハードウェアバージョンでは、同じハードウェアでこの問題は発生していないようです。
