Does the voice part work for you? I configured all the mixers to
voice, and then am using

sudo aplay -D plughw:CARD=Audio,DEV=1 /usr/share/sounds/alsa/Front_Center.wav  -r 16000
X11 connection rejected because of wrong authentication.
xcb_connection_has_error() returned true
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit
Little Endian, Rate 48000 Hz, Mono
user at devuan:/my/tui/rweb$

to play the test sound. But I get white noise, not a test sound
:-(. [This also shows problem with card naming.]

Any ideas?
