audio-io handles not supported stream type

[Version] 0.3.8
[Profile] Common
[Issue Type] Feature
[Dependency module] NA
[Dependency commit] NA
[Comment]
supported stream type:
 - audio-in/out   : voip, media
 - audio-in only  : voice recognition, loopback
 - audio-out only : system, alarm, notification, emergency, voice information, ringtone voip, ringtone call
 (reference : platform/core/multimedia/mmfw-sysconf / mmfw-sysconf-target-n4/etc/pulse/stream-map.json)
additionally, fixed TCT issues.
