Sound routing problem after EXTUSB unplug/replug

[auburnham]

I believe that sound routing through the EXTUSB is fairly new, but I've run into a repeatable problem with it. Once I plug the EXTUSB in after boot, the sound routes through the connection as expected. However, if I pause the playback, unplug the EXTUSB, and then plug the EXTUSB back in, the sound does not route through the EXTUSB. I've found that if I toggle speakerphone on & off, then the sound will correctly route through the EXTUSB connection again.
Until there is a permanent fix for this issue, I was wondering if there was a faster way to "restart" the sound routing, rather than calling voice mail, toggling speakerphone on/off, disconnecting, and returning to the original app.
