ALSA: Define more channel map positions
For following the standard, define more channel map positions and shuffle the items a bit: - As both PulseAudio and gstreamer define MONO channel position explicitly, we should follow that, too. The mono streams point to this channel position unless they are explicitly assigned to certain channel positions. - Top-front-* and Top-rear-* positions are added, carried from PulseAudio's definitions. - Move NA and MONO definitions at the top of table right after UNKNOWN, since these are more abstract in comparison with other practical positions.
