Title:
[ThinkPad T400s] neither internal nor external microphones work
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
When running Ubuntu 9.10 on a Lenovo ThinkPad T400s laptop, the
internal microphone worked as expected, but the external microphone
was never detected. After undergoing a distribution upgrade to Ubuntu
10.04, neither microphone works -- gnome-sound-recorder reports no
sound level while recording and changing the settings in gnome-
alsamixer doesn't have any discernible effect.
