Changing sound device does not enable save button at first

When changing the sound device in the options, you can't save if you just started the game.

It has done this multiple times now, but just trying it again... it now enables the save button. So this appears to only happen if you just started the game.

It also doesn't actually change the device until you make another change on the options. As soon as I change the master volume, the sound is using the correct device. Cancelling the changes does not actually change the device back at this point.

Edit: I should mention that I'm playing on Linux. If anyone on Windows could confirm this happens on Windows too, that would be great.
(Not sure how common it is to have multiple sound devices on Windows, though)
