我是 ubuntu 新手,遇到了声音问题,我浏览网页已经两周了,试图解决它。
一切都运行良好,直到我尝试使用我的 everyman hd 麦克风/耳机与 skype 一起使用。它确实显示在输出/输入声音设置中,但没有工作。重启后,我失去了声音设置中的所有内容,但如果我在终端中输入 alsamixer,我可以看到所有可用的声卡。抱歉,我无法在此处显示任何屏幕截图,因为我没有 10 个声誉点 :(
如果我输入 aplay-l,则会得到以下内容:

我目前所做的:
- 尝试按照以下步骤删除 pulseaudio 并安装 alsa-mixer:https://help.ubuntu.com/community/SoundTroubleshooting#Line_Input.2BAC8-Microphone_Troubleshooting
- 按照以下步骤升级 Alsa:https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS
如果你能帮我摆脱这种困境那就太酷了!;)

似乎在重新执行问题末尾的步骤后一切都恢复正常;)如果有人遇到同样的问题,也请尝试这样做。
谢谢
