Public bug reported:
Previously in Karmic there was bug #453966 which made the default input
source the front mic jack instead of the integrated microphone, though
this could be worked around / fixed by changing a switch in alsamixer.
However in Lucid the integrated microphone seems to no longer be
recognized at all, and there is no such switch alsamixer switch anymore,
so it seems like there is actually no way to use the integrated mic
anymore.
Let me know what other info I can provide! I am happy to test
dailies/PPAs as well.
