Installed a Mic+ hat on a pi zero running vanilla raspbian 10 (buster). Install went fine as per docs, everything is working (running rhasspy voice assistant to control HomeAssistant). Only issue is alsamixer volume control has no impact (on onboard speakers). I need to drop the volume a bit as the voice is badly distorted. card choice in alsamixer is " - default" and “0 snd_rpi_googlevoicehat_soundcar” … both which show the same thing. If I choose All (playback and Capture) … I see 2 master and 2 micro … both of which move in sync and none that changes volume. Any ideas?
