所以我刚为我的 Linux 机器买了这款游戏耳机，麦克风非常安静。麦克风音量调到最大，如果其他游戏声音不是很大，在游戏中可以听到，但它非常安静。
音频面板中的增益选项显示为灰色。
有什么想法吗？除了更换驱动程序，我已经尝试了所有能想到的方法。
谢谢。

答案1
检查 ALSA 录音设置 - alsamixer -c 0 --view capture
除了通常的音量控制外，还可以通过附加控制将麦克风音量提高 10dB 或 20dB
建议在增加升压之前先降低水平！
命令amixer -c 0将以文本格式显示相同的 ALSA 信息。
使用“set”选项的 amixer 命令可用于更改任何设置
麦克风 ALSA 级别的提高也应显示在 Pulseaudio 中
