我的静音键、降低音量键和提高音量键都可以使用，但是上一个键、下一个键和播放/暂停键则不工作。
我尝试了发布的解决方案这里，但这似乎不是问题。我的所有org.gnome.settings-daemon.plugins.media-keys设置似乎都以 XF86 为前缀：
以下是按顺序按下上一个、下一个、播放/暂停和静音的输出：

我决定进一步研究一下这个问题。显然，如果你有 USB 键盘，你需要使用evtest而不是showkey获取正确的扫描码：
$ sudo evtest

我能够验证我的钥匙是否正常工作将它们重新映射到字母：
$ cat /etc/udev/hwdb.d/90-custom-keyboard.hwdb
evdev:input:b0003v1130p7979*
KEYBOARD_KEY_c00cd=a
KEYBOARD_KEY_c00b6=b
KEYBOARD_KEY_c00b5=c
$ sudo udevadm --debug hwdb --update
$ sudo udevadm trigger
现在我可以用上一个、下一个和播放/暂停键输入字母了。接下来，我使用xdotool测试按键：
$ xdotool key XF86AudioLowerVolume
$ xdotool key XF86AudioRaiseVolume
两者都有效，但以下任何一项都不起作用
$ xdotool key XF86AudioPlay
$ xdotool key XF86AudioNext
$ xdotool key XF86AudioPrev
这让我觉得 Unity 的媒体播放器集成有些失误。我不确定如何检查 Unity 在后台是否做了正确的事情。有什么想法吗？

答案2
正如@Jeffrey 所说他的回答媒体键适用于 rythmbox v.3.3。它们也适用于 totem v.3.18.1，无需调整。
也可与 Rosewill RKM-1600RF (RF6560) 2.4GHz 无线多媒体键盘配合使用
