无法录音原因总结

 原因十：dsp已经出现异常。

从所提交上来的log来看，在录音出现异常之前，playback已经出错，也就是说dsp已经出现异常。但是，从这份log，无法判断dsp出现异常的原因。
Line 38946: 09-23 11:15:32.152  5748  5857 E alsa_pcm: cannot open device '/dev/snd/pcmC0D0c', errno 16
Line 38947: 09-23 11:15:32.152  5748  5857 E ALSADevice: open: Failed to initialize ALSA device 'hw:0,0'
Line 38948: 09-23 11:15:32.152  5748  5857 E AudioHardwareALSA: Error opening pcm input device
是因为点启动录音的时候，在打开PCM设备时发现所要打开的PCM设备已经打开。而之所以一直这样，是因为某一次操作后，已经无法从dsp读取上行的录音数据，然后有一个进程或线程不停的在尝试恢复（见附件图片），导致/dev/snd/pcmC0D0c设备一直没有关闭。从而错误发生后，每次点击录音，都会报16号错误，并提示其他程序正在使用录音机。

原因九：录音的底层设备被占用，框架层改变了录音设备，导致框架层和录音底层设备不一致，导致上层AP无法获得 input 导致无法录音

100%出现步骤为：未插入耳机进入i Mic录制一段录音，暂停录音后插入耳机home键退出，再进入录音机就能出现设备被占用（或者插入耳机时录制，暂停时拔插耳机类似操作，或者切换mic后类似操作）

a. 原因分析：iMic中创建AudioRecord进行录音会在驱动策略层新建对应的输入设备管理，如果另外的应用需要开启输入设备，输入设备需要和已有的输入设备是同一个，否则不能开启，分析Log发现iMic使用的是手机麦输入设备，停止录音后有插入耳机，此时如果AudioRecord仅仅是停止而不是release的话对应在驱动策略层的输入设备管理是不会被删除的，而系统在插入耳机时不会重新针对应用端进行底层输入设备的路由，导致此时系统内还是iMic对应的输入设备还是手机麦，此时再开启录音机录音就会提示设备被占用
b. 修改方法：凡是iMic内停止录音应用的AudioRecord一律release掉，重开其它应用的输入设备就无需在驱动策略层重新对比，避免设备被占用的情况

原因八：DSP打开失败造成，DSP内部ADM模块打开超时。导致无法录音，kernel log有报错，这个错误是读取adm copp状态时超时产生的。

原因五：MIC和底层录音设备没打开，导致无法录音

MTK的MIC是否打开：

AUDADC_CON0 = 0xb4，ADC都没打开

从贵司reg值来看是b4，ADC left/right power down
正常应该是93
请贵司提供audiomachinedevice.cpp分析

高通的MIC是否打开：

/sys/kernel/debug/asoc/apq8064-tabla-snd-card/tabla_codec

原因四：modem死亡，或者modem发生异常时，导致无法录音

mtk判断modem是否正常的方式：

adb shell cat /sys/class/BOOT/BOOT/boot/md  确认下Modem状态：0, or 1, or 2, or 3
0,1 表示还没有ready
2   表示正常
3   表示有exception

qcom判断modem是否正常的方式：

如果modem起不来或者modem死掉，adb shell ls /dev/efs_hsic_bridge后会显示什么？
曾庆明(曾庆明) 14:37:36
No such file or directory

如果modem正常工作，adb shell ls /dev/efs_hsic_bridge后会显示什么？
C:\Users\Administrator>adb shell ls /dev/efs_hsic_bridge
/dev/efs_hsic_bridge

原因三：单路录音中,其它AP无法获得input，导致无法录音

原因一：Audio相关的音频服务死亡，导致无法录音。举例如下：卸载sdcard卡有问题,强行杀掉了如下服务，导致无法录音。
