I experience the audible clicks with VLC but I have reproduced it with aplay as well. The clicks that I hear corresponds to underruns. For the records, this is not happening with a USB device. I have a Intel HDA sound card.
Ok, sorry. I missed that detail.
I did chime in the discussion to point out that the problem could come from something else than ALSA or the sound card driver. Here is the output of my aplay session. This makes me doubt my hypothesis. I'll check the cpu usage while the Wifi is on but not connected or see if running aplay in real-time prio makes things any better.
I see, and I'd say that's a sign that the wifi driver is holding off the system way too long somewhere, rather than a problem with the sound driver.
Could you repost your findings from the earlier mail and send them to Larry.Finger@lwfinger.net and linux-wireless@vger.kernel.org? The wireless people might have an idea what's going on.
