これを修正する方法がわかりません。カーネルを再インストールしようとしましたが、役に立ちませんでした。

Fedora 22-> 27のアップグレード後にこの問題が発生しました。新しいグループが原因でした。 sndデバイスにアクセスするには、audioグループのメンバーである必要があります。

~ > ll /dev/snd/controlC* crw-rw----. 1 root audio 116, 2 Mar 31 08:27 /dev/snd/controlC0 crw-rw----. 1 root audio 116, 9 Mar 31 08:27 /dev/snd/controlC1

idでグループを確認してください。 usermod -G audio,... <myuser>で追加しましたが、他の方法があるかもしれません。

これは設定ミスです。名前の変更~/.config/Pulse、次にデスクトップセッションを再起動します（ログアウト、ログイン）

システム全体のサービスとしてpulseaudioを実行する必要があり、あなたが説明したダミー出力の問題がありました。

私の場合、この記事に従って解決しました https://rudd-o.com/linux-and-free-software/how-to-make-pulseaudio-run-once-at-boot-for- all-your-users およびオーディオグルー​​プにPulseユーザーを追加します。
