I just confirmed latest nightly build (of_v20180502_ios_release) has no problem above. Both input and output of the sound works correctly on the audio input example.
It seems that the sound playing function is switched from OpenAL to AVAudioPlayer. So I still need to check if sound play latency of AVAudioPlayer is feasible for my project… But I see the sound input problem in the example itself will be solved in a future release.
Hi,
For those who needs to use OF 0.9.8, a workaround is to play audio in an other thread (with ofThread).
I did that, and I can both record and play audio at the same time.
