...> So I copied the
/etc/modprobe.d/alsa-base.conf file from the running
US12 environment to
my system partition, rebooted, and QJackCtl starts jack with no problems
and Yoshimi is currently making lovely sounds through the Audiophile.
The only audio devices that appear are the Audiophile (card 0) and HDMI
(card 1).
Maybe paste your current, working contents of /etc/modprobe.d/alsa-base.conf here so if
anybody else is having a similar problem they can see what worked for you :)
Dale.
