The filetype you are attempting to upload is not allowed.

Code Shown below:

    $config['upload_path'] = getwdir() . 'voices/';
    $config['allowed_types'] = 'wav|mp3';
    $config['max_size'] = 2800000;
    $config['file_name'] = rand();
    $this->upload->initialize($config);
    var_dump($config);
    if ($this->upload->do_upload('file')) {
        var_dump('uploaded');
    }else{
        var_dump($this->upload->display_errors());
    }

var_dump($_FILES['file']);

  array (size=1)
 'file' =>

When using the upload library with these config values:

$config['upload_path'] = 'uploads/';
$config['allowed_types'] = 'wav';
$config['max_size'] = '1000000';
$this->load->library('upload', $config).

If you attempt to upload a .wav file (tested in firefox 7.0.1). It will report an error of 'The filetype you are attempting to upload is not allowed.'.

This can be solved by replacing line 68 in application/config/mimes.php

'wav' => 'audio/x-wav'
 with:
'wav' => array('audio/wav', 'audio/wave', 'audio/x-wav'),

Ok If you Tried it already then try this:

You could try looking at system/libraries/Upload.php line 199:

$this->_file_mime_type($_FILES[$field]);

Change to

$this->_file_mime_type($_FILES[$field]); var_dump($this->file_type); die();

Then do upload your .wmv file. It would show something like application/octet-stream or whatever. Add that to your mimes.php.
