Mic doesn't work when in loudspeaker mode

[joelselvaraj]

I tried this fix in 87528c9. When the loudspeaker is enabled, the speaker is working, but the main mic below the phone doesn't work and whatever we speak is not audible in the other end. However the mic in the top(near IR sensor) is working, but we need to hold it closer and upside and speak.

Can you confirm the issue? Or its working for correctly for you?
