已完成的排查步骤 #

• 已在Manifest中配置正确录音权限，设备已开启录音权限，应用首次安装时也请求了运行时权限
• 检查Java源码未发现问题，推测故障出在原生库层面
• 尝试在系统完全初始化后的不同时机执行初始化操作，问题未解决
• 测试过多个Android版本，故障依然存在
• 已在TinkerBoard论坛发帖求助，现针对系统层面问题再次咨询

新发现的线索 #

发现音频设备目录中缺少pcmC0D0p文件，当前目录内容如下：

crw-rw---- 1 system audio 116,   6 2013-01-18 08:50 controlC1
crw-rw---- 1 system audio 116,   8 2013-01-18 08:50 controlC2
crw-rw---- 1 system audio 116,   5 2013-01-18 08:50 pcmC1D0p
crw-rw---- 1 system audio 116,   7 2013-01-18 08:50 pcmC2D0p
crw-rw---- 1 system audio 116,  33 2013-01-18 08:50 timer

提问 #

直接修改这些音频设备文件的命名是否安全？能否解决当前的Picovoice初始化故障？
