Alexa with Raspberry Pi4 and Matrix Voice

Hi Team,
Is there any update on the support of the Matrix Voice on Buster (RPI4)?

I have the same problem with the creator.

After a lot of research it appears there is a breaking change in the Broadcom ALSA driver that is causing port audio to fail. It will not correctly select you default device.

@rysmith0315 & @deepakgupta,

The MATRIX Voice does work with the RPi 4 on Buster. However, our matrixio-kernel-module package is currently down due to some updates which may be causing your problems.

A temporary solution is to purge the package installation of the MATRIX kernel modules and compile from source.

sudo apt purge matrixio-kernel-modules

Then, follow steps here.

Apologies for any inconvenience and please reach out if with any further questions/concerns/suggestions.
