where i can find the generated sound from Amazon to test it on another device.
where i run: smarthome:audio play doorbell.mp3
i hear sound from OpenHAB.
but when i play another test file from OH
smarthome:audio play barking.mp3
there are no sound. May be problems in audio formats? How i can change default sample rate from Amazon synthesys files? I use OH 2.5.0 m1 and latest version of binding
Has anyone had a problem with more recent versions of specific voices not working? For example, I use the “Brian” voice. I’ve had to back out to the 2.3.0 version so that it works. Otherwise I get an error along the lines of “can’t find that specific voice”. It seems like it connects properly otherwise.
