Comment 22 for bug 433055

Bug 331130 discusses a problem on the eee with its array microphone. I wonder if in some circumstances PA or the ALSA driver on the Aspire One is assuming that we have an array microphone too, where really we only have a single one (as far as I know, anyway). If you treat the input as sum and difference, as described in 331130, and subtract one from the other where really we have identical input on both channels (mono really), you end up with silence!
