-Subject: [PATCH] [Audioinjector] Fix bit offsets for equal volume and add 8
- kHz operation (#1727)
-
-Applying to the audioinjector sound card only. This patch offsets channel
-2 correctly from the LR clock. This ensures that channel 2 doesn't loose
-any bits during capture. It also results in both channels 1 and 2 having
-the same volume. This commit also adds 8 kHz operation.
