MTK播放声音的函数:
(1).mdi_audio_snd_play_file_with_vol_path();这个函数是播放声音文件的函数,第一个参数是文件的路径,注意如果是U8类型,只能播放英文文件名的函数,一般应将文件名设置为U16型的.
(2).mdi_audio_snd_play_string_with_vol_path();这个函数是播放资源类型的声音文件.

void play_aud_test()
{
U32 audio_len;
U8 *audio_data;
U8 audio_type;
U16 repeat = 1; /* Play once */
mdi_result result;
audio_data = get_audio((U16) (AUD_ID, &audio_type, &audio_len);
if (audio_data != NULL)
{
     result = mdi_audio_snd_play_string_with_vol_path(
                 (void*)audio_data,
                 audio_len,
                 repeat,
                 NULL,
                 callback,
                 volume,
                 speaker);
}
}

在这个函数里面,先要从资源中根据资源id获取到生硬数据,同时,可以得到声音类型和声音的长度.然后再用该函数播放之.

(3).如果要录音的话,首先要发出请求,mmi_sndrec_send_record_req();然后把录制的数据保存到自己的文件中,这个具体的录制过程不得而知,mtk对其做了封装,只需要发送这个消息给底层就可以了.所录制的声音都保存在SoundRecorder.fullname这个文件里面.
