Follow-ups

Yes. I have repeated it. After connecting a call, from PC, we can only hear the

audio from target for 2-3 seconds, then no sound again. Using ad1980 to run the

same case, there is no this problem.

A simple debug shows capture DMA hasn't stopped after audio disappears using

AD1836. Let me check what's the reason.

It should be a duplicate bug with the AD1836 record overrun and playback

underrun in bf533. After more careful debug, according to the flow trace,

capture overrun triggers the SNDRV_PCM_TRIGGER_STOP, but there is no

SNDRV_PCM_TRIGGER_START trigger again. So DMA stops and doesn't start again.

Refer to the duplicate bug

[#3908] For BF533-STAMP with AD1836/AD73311/AD1981b, there will be under run or

overrun errors

So close this bug.
