Custom notification sound

[danielhatton]

An odd problem:

In the beginning, everything was fine: when I got a boost, or a mention, or a favourite, Tusky would send a notification through the Android notifications system, and it would make the default bing-bong sound (I presume selected by the phone manufacturer).

But then I tried to get clever: I found the notification sound settings for boosts, mentions, and favourites on the relevant account, and set them to point to a wav file in my Ringtones folder.

Now, when I get a boost, or a mention, or a favourite, a Tusky notification still appears in the Android status bar, and the phone vibrates, but there's silence: the wav file is not played.

What's more, I can't find any way to set the notification sound back to the default.

Any ideas, please?
