Cannot use internal Mic on Lenovo T500

The PulseAudio Sound Preferences appears to give no way of using the internal microphone on a Lenovo T500 running Debian Testing. The Input volume control appears to be for the mic input socket, there is no control for the internal mic. Using the Gnome ALSA Mixer there are extra controls over and above what the PulseAudio Sound Preferences offers. In particular there is a control Internal, which is required to set the input level of the internal microphone -- the power on default is zero which means the microphone is not providing source signal.
It isn't actually clear where the problem resides, it may or may not be a direct PulseAudio issue, but I was advised to submit a report here anyway since PulseAudio is the default sound system control and it should be able to control all the sound sources.
In a sense this is a blocking bug, but there is a simple workaround so it is not actually blocking.
I appreciate this may not be a suitably complete bug report, but I can provide any appropriate information needed as required.
