By asking for buffer-time=10000, you are only providing 10ms buffering in the audio device - if the audio thread starves for more than 10ms, you are in trouble. Unless you've taken care to ensure that your kernel provides fine-grained timeslices and that the system isn't going to be too busy to service the audio thread, that'll be fine, but unless you really need the low-latency behaviour (you don't for just playing music), why not set it higher?
