Public bug reported:

Just as the title says, if a usb sound card is in use pavucontol's
settings are ignored. This appears to be an unintended result of the
changes made to address bug #1702794. Specifically if you now look at
/etc/pulse/default.pa you'll find this section:

### Use hot-plugged devices like Bluetooth or USB automatically (LP: #1702794)
.ifexists module-switch-on-connect.so
load-module module-switch-on-connect
.endif

So you must comment out those three lines in order for pavucontrol
device default settings to be respected if a usb sound card is plugged
in at reboot or startup. It's not a big deal but I hadn't run across
this in the past and couldn't find an existing bug report.
