I think my screen is quite happy with the chair it is placed on while I sit in half-lotus position on the floor.
One might argue it would be wiser to sit in the chair yourself, but that kinda would be cheating. It's already getting better even though I am still a lightyear away from reaching full lotus without breaking my legs with a crowbar first. Well, after all - no pain, no gain.

Back to topic - I noticed occasional clunking sounds in the alpha tracks. Were they inserted on purpose like the voice, just artifacts or am I already going insane?

I can't seem to able to hear any of the sounds on my tablet or my phone, even though the video works perfectly. (I've tried the Constant Alpha and the Ascending Theta)
Is there any way I can fix this?

EDIT: Fixed my problem. I converted the .mp4 file to a  .wmv and it seems to be working perfectly.

Uh, I don't want to be a dick but the sounds really are there.
In the beginning I really thought they were something in the background like my cat but they always remained the same so I took a closer look. You can hear one example in Constant Alpha at 4:30, two distinct 'beats' in rapid succession.

I made some (pretty ugly) sonograms to show what I found.

1) Three normal alpha beats @ 4:34
2) The background voice as dark line in the lowest frequencies @ 4:26
3) Here's what I mean - some low frequency sounds @ 4:30
