I have RP3 B+ with raspiaudio voice hat. I don’t think mycroft’s hearing is very good. He speaks well, but when I tell him to record the play-back sound quality is very poor. Als when I say Hey Mycroft he doesn’t always hear.
I have tried tweeking the levels in alsamixer, but they are never stored on reboot. I have also tried alsctl store, but that does not work either.
In alsamixer I have 2 soundcards - ‘default’ and ‘Sound_rpi_googlevoicehat_soundcard’. Each one has two level indicators, capture and master. I could do with an explanation which card and what is master and capture
Can anyone offer some advice please
