use of int16_t/uint16_t. This is the upshot of a recommendation by henrik.lundin and kwiberg on an original small change ( https://webrtc-codereview.appspot.com/42569004/#ps1 ) to stop using int16_t just because values could fit in it, and is similar in nature to a previous "mass change to use size_t more" ( https://webrtc-codereview.appspot.com/23129004/ ) which also needed to be split up for review but to land all at once, since, like adding "const", such changes tend to cause a lot of transitive effects. This was be reviewed and approved in pieces: https://codereview.webrtc.org/1224093003 https://codereview.webrtc.org/1224123002 https://codereview.webrtc.org/1224163002 https://codereview.webrtc.org/1225133003 https://codereview.webrtc.org/1225173002 https://codereview.webrtc.org/1227163003 https://codereview.webrtc.org/1227203003 https://codereview.webrtc.org/1227213002 https://codereview.webrtc.org/1227893002 https://codereview.webrtc.org/1228793004 https://codereview.webrtc.org/1228803003 https://codereview.webrtc.org/1228823002 https://codereview.webrtc.org/1228823003 https://codereview.webrtc.org/1228843002 https://codereview.webrtc.org/1230693002 https://codereview.webrtc.org/1231713002 The change is being landed as TBR to all the folks who reviewed the above.

INSTRUCTIONS: - Start with test #3 (Device enumeration) to get an overview of the available audio devices. - Next, proceed with test #4 (Device selection) to get more details about the supported functions for each audio device. - Verify two-way audio in test #5. Repeat this test for different selections of playout and recording devices. - More detailed tests (volume, mute etc.) can also be performed using #6-#11. NOTE: - Some tests requires that the user opens up the audio mixer dialog and verifies that a certain action (e.g. Mute ON/OFF) is executed correctly. - Files can be recorded during some tests to enable off-line analysis. - Full support of 'Default Communication' devices requires Windows 7. - If a test consists of several sub tests, press any key to start a new sub test. KNOWN ISSUES: - Microphone Boost control is not supported on Windows Vista or Windows 7. - Speaker and microphone volume controls will not work as intended on Windows Vista if a 'Default Communication' device is selected in any direction.
