Bug Description
I recently pressed the physical microphone mute button on my Lenovo T410. However, I am now unable to unmute it. The orange light next to the mic mute button comes on when the kernel boots, but pressing it has no effect.
Possibly related to this, I am now unable to unload the thinkpad_acpi kernel module (required to run the fan in disengaged mode to work around the long-standing bug 751689) as it seems to be permanently hooked into the sound drivers:
$ sudo modprobe -r thinkpad_acpi
modprobe: FATAL: Module thinkpad_acpi is in use.
$ sudo lsmod|grep thinkpad_acpi
thinkpad_acpi 69003 1
nvram 14027 1 thinkpad_acpi
snd 60871 23 snd_hwdep,
$ sudo modprobe -r thinkpad_acpi snd_hwdep snd_timer snd_hda_codec_hdmi snd_hda_
modprobe: FATAL: Module thinkpad_acpi is in use.
