[Pianod] Pianod downloader, libao boot issues (pi: to exclusive)

[Perette Barella]

We've tried everything I can think of on our end... I think adding some kind of startup delay is probably the easy answer, if you want to delve more deeply ask about the issue on libao's mailing list since it's their library that handles the audio I/O.

Let me know if that fixes the boot-up problems with the libao default device, if so there's a bit more work to make it work with other devices.
