VS1003录音后无法播放

我目前已经实现了VS1003的录音功能，能在耳机里听到自己的声音，然后按照官方的代码将数据读出并且存在了FLASH里，但是直接从FLASH里将数据读出送到VS1003里却没有任何反应，这是怎么回事啊？

[mw_shl_code=c,true]void VS1003_SoftReset(void) { uint8_t retry; while( MP3_DREQ ==0 ); VS1003_SPI_ReadWriteByte(0xff); retry = 0; while( VS1003_ReadReg(0) != 0x0804 ) { VS1003_WriteReg(SPI_MODE,0x0804); delay_ms(2); if( retry++ > 100 ) { break; } } while( MP3_DREQ ==0 ); retry = 0; while( VS1003_ReadReg(SPI_CLOCKF) != 0X9800 ) /* ?è??vs1003???±??,3±??? ,1.5xADD */ { VS1003_WriteReg(SPI_CLOCKF,0X9800); /* ?è??vs1003???±??,3±??? ,1.5xADD */ if( retry++ > 100 ) { break; } } retry = 0; VS1003_WriteReg(11,0x2020); MP3_DCS(0); VS1003_SPI_ReadWriteByte(0); VS1003_SPI_ReadWriteByte(0); VS1003_SPI_ReadWriteByte(0); VS1003_SPI_ReadWriteByte(0); MP3_DCS(1); delay_ms(20); } [/mw_shl_code]

这些就是关键的函数了，请原子哥帮忙看下，RIFF头文件我也加了。
