Whenever sets the bufferNum to be 4. It get stuck in the for loop of “filling all buffers with silence to prepare for playback”.

However, some of my other co-workers who are using 2.02 version. He works all well with 4 DSP buffer.

I’m just wondering whether there’s something different with 4.44 version, which prevents me from setting buffNum to be 4, or shall I do any other ops to make it work?

Huge thanks for anyone helps!!!

Just to double check, for the 4.44 version, do you mean FMOD Designer / FMOD Ex?

If that’s the case, unfortunately, FMOD Designer / FMOD Ex does not support Open Harmony. I will add a task to add better clarification in our documentation, thank you for bringing this to our attention.

For Open Harmony support, could you please update to FMOD Studio? We would suggest keeping the version up to date.
