Ubuntuで音が出ない、ダミーの出力、サウンドカードが検出されない
これは、Ubuntu 18.04.4 LTSにSkypeをインストールした後に発生しました。 Skypeには音が聞こえないので、解決策を探しました。誰かがpavucontrolのインストールを提案しました
Sudo apt install pavucontrol
その後、Skypeの問題は解決せず、ラップトップでオーディオ出力が失われました。
たくさんのソリューションをオンラインで試しましたが、どれも機能しません。ここに私がすでに試した解決策があります。
# solution 1
pulseaudio -k && Sudo alsa force-reload
# then I did
pacmd list-cards
# which gives me
0 card(s) available.
# I also tried
aplay -l
aplay: device_list:270: no soundcards found...
#solution 2
Sudo apt-get update
Sudo apt-get dist-upgrade
Sudo apt-get autoremove
Sudo killall pulseaudio
rm -rf ~/.config/Pulse
pulseaudio -k
私はこれらを試し、ラップトップを再起動しました。しかし、どれも機能しません。私のラップトップはhp spectre x360です。助言がありますか？どうもありがとう！
