Hi Rachael
Sorry that nobody is replying, but I think it is because this is not easy to implement and not a lot of people are desiring this
There is a linux driver
here.
But I dont know linux, so it may not be fitting to iLiad. I think the best way would be, if the manufacturer of the mic would provide a linux driver. When the driver could be implemented the rest should be not a big problem.
Here a site with a
lot of linux sound applications
