googlesamples-assistant-hotword doesn't reply

[wxgithub]

I installed Google Assistant on an ARM board. pushtotalk sample app works fine, but if I run hotword sample, I couldn't get any reply. Do i need to change anything to make this to work?

Console messages look normal:

By ARM board, do you mean the Raspberry Pi? It looks like everything works except for audio output.

[wxgithub]

No, not Pi. It is Samsung ARTIK530 board (https://www.artik.io/modules/artik-530/). Right, looks like everything works except for audio output. As mentioned, audio output works fine with pushtotalk sample. What are the differences between these 2 sample apps?

[Fleker]

In the hotword sample, the audio output is more tightly coupled to the underlying code, so it may have certain dependencies on ALSA output that are not an issue when using the more generic Service API.
