Subject: Fix ALExtLoopbackDeviceSOFTTest

- Use max 4k to test
- Remove redundant default device/context
- Add AL source and assign buffer
- issue buffer play
- Only fail if certain accuracy is not met
  - Stereo 0.8 (passes w/ ~ 0.9)
  - Mono 0.4 !!! FIXME !!! (Only passes w/ ~ 0.49)

Tests are passing, however - have to check the MONO case.
