Xin chào, @nguyenhungsync.

Thanks for providing the output, that’s very helpful.

In this case, I think that alsa is unable to find the mixer control called 'Master`. I don’t know why though.

If you Ctrl + C out of the mycroft-cli-client and type the command alsamixer at the shell prompt, what results do you get?
