Asterisk chooses a file encoding based on the channel encoding. If your 
channel is encoded as GSM, Asterisk will not look for a .wav of the same 
name if a .gsm is available. If the .gsm is not available, Asterisk will 
use the .wav with the additional 'overhead' of transcoding the data to 
GSM.

Without any console log, these are just guesses:

1) Don't specify the file type in your dialplan. Asterisk chooses a file 
type for you based on channel encoding and formatting modules loaded. Is 
format_wav.so loaded?

2) Your WAV file is not encoded correctly. The 'file' command should show 
something like 'RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 
bit, mono 8000 Hz'

3) You have permission issues. From a shell, as the user your instance of 
Asterisk runs as, can you access the file?

If this doesn't help, please repost including the relevant dialplan 
context (as displayed by 'dialplan show <relevant-context-name>) and a 
snippet of the console log of a call playing the WAV file.
