[alsa-devel] [PATCH 1/1] BAT: Add default device name for playback and capture

[han.lu at intel.com]

From: "Lu, Han" <han.lu at intel.com>

If the playback device and the capture device was not set through
'-D', '-P' or '-C' options, set the name of the two devices to
"default". So by default, BAT will work through PulseAudio sound
server on Ubuntu/Debian, and work though CRAS sound server on
Chromium OS/Chrome OS.

If the playback device or the capture device was set through '-D',
'-P' or '-C' options by user, the device name "default" will not
be set.
