[gentoo-user] alsa switches to IEC958 - no sound from speakers

[Mick]

Something went sideways recently and I now find that only IEC958 is available 
as the default audio device.  Trying to change it to an analogue device does 
not take.  This PC has alsa only, no pulseaudio.

There is no /etc/alsa/, or /etc/asound.conf, or ~.asound.rc


How do I take back control of the default audio device on this PC?
