If the problem was localized to 17.10 then I would have said try undoing a recent change we introduced to /etc/pulse/default.pa:
### Use hot-plugged devices like Bluetooth or USB automatically (LP: #1702794)
.ifexists module-switch-on-connect.so
load-module module-switch-on-connect
.endif
But that's probably not relevant if you had the same bug in previous Ubuntu versions.
There is however this module that's been enabled for a long time and isn't documented so I'm not yet familiar with its behaviour. Perhaps commenting this one out would help:
### Should be after module-*-restore but before module-*-detect
load-module module-switch-on-port-available
