I finally have it working with esphome. Unfortunately I'm unable to use it - or any local device - for a voice assistant. My host is too old without AVX to host Whisper. However I still have it working as a smart speaker able to play media and tts just fine (not easy!). However the volume is too low no matter what I do. I can hear it but barely. From the marketing pictures the speaker appears to be 8 ohm at 3W. I have a few Gen1 Amazon Dots and they appear to be only about 1.2W and are much much louder than the AS. Are there any hints to maximize the volume? I'm running the most current version of Esphome builder and Home Assistant as of the date of this post.
I've commented out volume_max as it is said the default is 100%, but I've tried many values with no improvement.
Thanks for any help

Here's the yaml
