<pre>I think that the difference can be explained by the fact that PulseAudio,
unlike aplay, at startup, tries to open many different PCM devices for probing
purposes. In other words, PulseAudio probes for spdif, analog (in various
forms) and hdmi, and aplay opens, ultimately, only the hw:0 device that is
responsible for analog output. Probing for spdif can explain the clicks that
you heard. Also, PulseAudio (unlike aplay) touches mixer settings at startup,
that can also be the relevant difference.</pre>
