Was happily listening to my Karma when it suddenly stopped playing mid-song. It had locked up hitting the powerdown button just bought up the hourglass and it started clicking.

It does

clickclickclickclickclickclickbeep
clickclickclickclickclickclickbeep
clickclickclickclickclickclickbeep
etc

Had to resort to a paperclip reset, and now when I turn it on the display freezes at the Rio splash screen and it continues to click.

Is it knackered? I really hope it isn't - if it is, it doesn't say much for Rio reliability.
