Wav file with G.723.1 codec can not be played in Windows Media Player of Windows 8

To solve the issue follow the advice on this link:

"I ended up copying the msg723.acm file from a Windows 2003 Server,  dropped 

it in the \windows\syswow64 directory, then creating a registry entry to the
file under
HKLM\Software\Wow6432Note\Microsoft\WindowsNT\CurrentVersion\Drivers32
REG_SZ  msacm.msg723 = msg723.acm .

Now the codec shows up in the Media Player About listing and I can play back 

the call recordings.

Indeed it works much better now.  I have this kind of file generated a voice recording in Altigen MaxACD Call center WAV G.723.1 ((khz, 8bit, Mono, 0.8kb/sec)

the other choice is WAV GSM and WAV PCM. The latter can be played in Media Player out of the box.
