It can record the audio but cannot get timestamps.
Check the getstate() before call gettimestamp(). It is **StreamState::Started.**
The error comes from https://github.com/google/oboe/blob/a0731d6041561da9a15efdfd4ed49718b57bf5b4/src/aaudio/AudioStreamAAudio.cpp#L661-L662

It may be the error from aaudio.

call mInputStream->getTimestamp(CLOCK_MONOTONIC)
**Expected behavior**
Get the timestamp
**Actual behavior**
return the error result
