I've run for speaker-test, aplay, it plays well for sound file.

What's wrong with my Raspberry Pi and shairport-sync? I have no idea.

Thanks for the post. It looks a bit like that the audio data from your Airplay device isn't getting through properly, giving rise to those Aliasing of buffer index – reset messages. What kind of a device / software is the source? It would be worth checking the TROUBLESHOOTING.md page for a few hints.

@mikebrady Ahh, I've solved by allowing some ports described on TROUBLESHOOTING.md Thank you so much!! Such an awesome repo. You rock!

[mikebrady]

Great.
