I have a rapsberry pi zero w running Alexa from the tutorial here:
I tried connecting a bluetooth speaker but it really didn’t give me the results I needed so I bought the pHAT speaker. I have installed all the drivers etc but when I start the Alexa service I get an error that:
[b3f01f20] alsa audio output error: cannot estimate delay: Input/output error
Is there something I need to do to ensure that alsa can work with the pHAT?
