Are there experiences in running a Matrix Voice on Raspian/Debian Bullseye?
Normal installation fails:
... Reading package lists... Done E: The repository 'https://apt.matrix.one/raspbian bullseye Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. Reading package lists... Done Building dependency tree... Done Reading state information... Done E: Unable to locate package matrixio-kernel-modules
I was able to build the drivers as suggested in this post but the Matrix Voice is not recognized:
$ aplay -l aplay: device_list:274: no soundcards found...
