If anyone has any objections, please let me know. ------------------ From: David Henningsson commit 18dcd3044e4c4b3ab6341c98e8d0e81e0d58d5e3 upstream. The internal mic input is phase inverted on one channel. To avoid people in userspace summing the channels together and get zero result, use a separate mixer control for the inverted channel.
