Unable To Upload Audio/FIile with Retrofit 2.0

I'm unable to upload audio file and some string to server. I'm using Retrofit 2.0 . i'm getting "Not Save" response as you can see on last else of php api .Please check below code.

PHP API CODE:

<?php
header('Content-Type: application/json');
if(isset($_FILES['file'])   && isset($_POST['section']) && isset($_POST['sub_category']) && isset($_POST['question']) && isset($_POST['optionA']) && isset($_POST['optionB']) && isset($_POST['optionC']) && isset($_POST['optionD']) && isset($_POST['answer']) ){
    //require database
    require_once('DbConnect.php');
$output=array();
$section=$_POST['section'];
$sub_category=$_POST['sub_category'];
$question=$_POST['question'];
$optA=$_POST['optionA'];
$optB=$_POST['optionB'];
$optC=$_POST['optionC'];
$optD=$_POST['optionD'];
$an=$_POST['answer'];
$ans=(int)$an;   
     $output['error'] = false;
     $output['message'] = "File  Uploaded Succesfully";
    $p=dirname(__FILE__);
    //echo $p;
$audio=basename($_FILES['file']['name']);
$size=$_FILES['file']['size'];

//echo $audio;
$audio=str_replace(' ','|',$audio);
$tmppath1=$_SERVER['DOCUMENT_ROOT'].'/upload/'.$audio;

if(move_uploaded_file($_FILES['file']['tmp_name'],$tmppath1)){
   
     $conn=$dbh->prepare('INSERT INTO toefl(section,sub_category,question,optionA,optionB,optionC,optionD,answer,file_url) VALUES (?,?,?,?,?,?,?,?,?)');
$conn->bindParam(1,$section);
$conn->bindParam(2,$sub_category);
$conn->bindParam(3,$question);
$conn->bindParam(4,$optA);
$conn->bindParam(5,$optB);
$conn->bindParam(6,$optC);
$conn->bindParam(7,$optD);
$conn->bindParam(8,$ans);
$conn->bindParam(9,$tmppath1);
$conn->execute();
    if($conn->rowCount() ==0){
$output['error'] = true;
$output['message'] = "File not save in db ";
}
elseif($conn->rowCount() !==0){
$output['error'] = false;
$output['message'] = "Question Uploaded Succefully ";
}
     
}else{
     $output['error'] = true;
     $output['message'] = "FIle Not Uploaded ";
}
 }
else{
     $output['error'] = true;
     $output['message'] = "Not Sent";
}
echo json_encode($output);

?>

Android Retrofit Code:

public interface FileUploadService {
    @Headers({"Content-Type: multipart/form-data",
            "Accept: application/json"})
    @Multipart
    @POST("quizappdb/uploadlistening.php")
    Call<MyResponse> upload(
            @Part MultipartBody.Part file,
            @Part("section") RequestBody section,
            @Part("sub_category") RequestBody sub_category,
            @Part("question") RequestBody ques,
            @Part("optionA") RequestBody optA,
            @Part("optionB") RequestBody optB,
            @Part("optionC") RequestBody optC,
            @Part("optionD") RequestBody optD,
            @Part("answer") RequestBody ans

    );
}

Below is Android File Uploading Code:

File file = new File(RealPathUtil.getRealPath(activity_add_question.this, fileUri));
        RequestBody requestBody = RequestBody.create(MediaType.parse("audio/*"), file);
        try {



            MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("file", file.toString(), requestBody);
            Log.d("name",fileToUpload.toString());
            //creating request body for file
            //RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
            RequestBody section = RequestBody.create(MediaType.parse("text/plain"), sec);
            RequestBody sub_section = RequestBody.create(MediaType.parse("text/plain"), sub);
            RequestBody question = RequestBody.create(MediaType.parse("text/plain"), ques);
            RequestBody optionA = RequestBody.create(MediaType.parse("text/plain"), optA);
            RequestBody optionB = RequestBody.create(MediaType.parse("text/plain"), optB);
            RequestBody optionC = RequestBody.create(MediaType.parse("text/plain"), optC);
            RequestBody optionD = RequestBody.create(MediaType.parse("text/plain"), optD);
            RequestBody answer = RequestBody.create(MediaType.parse("text/plain"), ans);

            //The gson builder
            Gson gson = new GsonBuilder()
                    .setLenient()
                    .create();


            //creating retrofit object
            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(" http://mazadtime.com/")
                    .addConverterFactory(GsonConverterFactory.create(gson))
                    .build();

            //creating our api
            FileUploadService api = retrofit.create(FileUploadService.class);

            //creating a call and calling the upload image method
            Call<MyResponse> call = api.upload(fileToUpload, section, sub_section, question, optionA, optionB, optionC, optionD, answer);

            //finally performing the call
            call.enqueue(new Callback<MyResponse>() {
                @Override
                public void onResponse(Call<MyResponse> call, retrofit2.Response<MyResponse> response) {
                    Log.d("fileres", response.body().message);
                    try {


                        if (!response.body().error) {
                            Toast.makeText(getApplicationContext(), "" + response.body().message, Toast.LENGTH_SHORT).show();
                            T//oast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
                        } else {
                            // Toast.makeText(getApplicationContext(), ""+response.body().message, Toast.LENGTH_SHORT).show();
                            Toast.makeText(getApplicationContext(), "Some error occurred..." + response.body().message, Toast.LENGTH_LONG).show();
                        }
                    } catch (Exception e) {
                        Log.d("Retrofit catch", e.getLocalizedMessage());
                    }
                }

                @Override
                public void onFailure(Call<MyResponse> call, Throwable t) {
                    Log.d("fileerror", t.getLocalizedMessage());
                    Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();
                }
            });
        }catch (Exception e){
            Log.d("Errop",e.getLocalizedMessage());
        }

But When i test api on postman it working perfectly.check it
