i’m using fmod on my android app to record sound with low level api getRecordPosition,it works just fine on many devices ,but on device vivo x85a,the call of getRecordPosition return FMOD\_OK but the position always zero,i tried many times most of time has this problem.any idea?thanks.

```
    do{
    ...
            /*
            Determine how much has been recorded since we last checked
            */
            unsigned int recordPos = 0;
            result = system-> **getRecordPosition** (DEVICE_INDEX, &recordPos);
            ERRCHECK(result);
            if (result != FMOD_OK) {
                LOGC("recording break :%s", FMOD_ErrorString(result));
                break;
            };

            unsigned int recordDelta = (recordPos >= lastRecordPos) ? (recordPos - lastRecordPos) : (
                    recordPos + soundLength - lastRecordPos);
            lastRecordPos = recordPos;
            samplesRecorded += recordDelta;
            if(recordDelta==0)
            {
                LOGC("zero recordDelta!recordPos:%d",recordPos); // **<-------- always hit**
            }
    ...
    }while(true)
```

Are you able to get any logging from the device when this occurs?
