. I was watching my TV, and suddenly an intense, extremely loud, piecing sound started being played from my Arc/surrounds. It was so loud that my ears are still ringing 15 min later. The only way I can describe it, is that it sounded like a commercial alarm system siren. I turned off my TV - nothing, unplugged the Arc Ethernet - nothing. Tried to lower the volume - no good. Finally had to pull the main power cord off the Arc to stop it.
I plugged everything back in and it is working fine so far.
This is very concerning. Not just the potential hearing damage, but damage to the speakers from blaring this noise so loudly.
Anyone else experience this?
