It has analogue audio out from a 3.5mm jack socket or digital audio from 
the HDMI connector. I don't know whether HDMI provides for a low-level 
input suitable for a microphone. Probably not.

I'm trying SpeakUp using speechd-up and speech-dispatcher tonight to see 
if that works any better. If not, the only way to avoid the vchiq (video 
core hardware interface queue) which causes the crash is to use USB audio.

Of course it could be that something SpeakUp is doing is causing the 
null pointer dereference in the kernel.
