W / audio_hw_generic：硬件支持HAL太慢，只能写入720帧中的0帧

Question

在AS logcat中我得到：

"W/audio_hw_generic: Hardware backing HAL too slow, could only write 0 of 
720 frames"

带

"W/audio_hw_generic: Not supplying enough data to HAL, expected position 
10090346 , only wrote 9938160
W/InputMethodService: Window size has been changed. This may cause jankiness 
of resizing window: -1 -> -2"

持续警告。 这个警告是什么？如何从中恢复？
