Title:
unable to toggle microphone mute on T410 / unable to unload
thinkpad_acpi module
Status in “linux” package in Ubuntu:
Incomplete
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
