My laptop speakers are producing a tapping sound which occurs every ~2seconds and only when there is not other audio playing. When I connect external speakers the tapping is even loder (and still coming from internal speakers). I remember this wasn't happening a while ago.

I have made a recording of it - SoundCloud stream.

lshw produces this output concerning audio:

         description: Audio device
         product: SBx00 Azalia (Intel HDA)
         vendor: Hynix Semiconductor (Hyundai Electronics)
         physical id: 14.2
         bus info: pci@0000:00:14.2
         version: 00
         width: 64 bits
         clock: 33MHz
         capabilities: bus_master cap_list
         configuration: driver=snd_hda_intel latency=64
         resources: irq:16 memory:fbaf4000-fbaf7fff

What can I do to eliminate this sound?

I sold the old laptop and now I have no problems anymore :) I still think it was a software problem though. – Primož Kralj May 7 '13 at 11:04
