Core

- Release v1.2.6.1

Configuration

- conf: fix the device parsing when arguments has no defaults

The commit bf528b90 sets the value to an empty string which causes
these errors:

   pcm_hw.c: Invalid type for device
   pcm_hw.c: Invalid type for subdevice

When device arguments (@args) have no default values set,
the field must be skipped to keep the compatibility.
