fail 信息如下：

-- test4_1MeasurePeakRms fail junit.framework.AssertionFailedError: peak deviation in mB=2797 at junit.framework.Assert.fail(Assert.java:50) -- test4_2MeasurePeakRmsLongMP3 fail junit.framework.AssertionFailedError: peak deviation in mB=2813 at junit.framework.Assert.fail(Assert.java:50)

解决方法

关闭besloundness再测试，这个菜单位于Settings/sound&notification/sound enhancement ，默认是开启的。 Note: xxxxx的DRC(BesLoudness)会在AudioEffect之前处理。该CTS测试项会在AudioEffect中取出data并计算PeakRms。由于DRC会对gain值产生影响，而CTS测试对gain值有所限制，所以BES_LOUDNESS_MUSICDRC_SB_GAIN会影响最终CTS测试的结果。
