I got a zvox soundbase (for free) but any ways it has worked normally once and had no problems otherwise everytime i turn it on (sometimes right away but usually within a minutenor two) it starts popping, crackling, and hissing...usually at full volume it seems even though i wasnt listening at that level. Its very annoying and also my dog iis scared to death of the thing...everytine i turn it on now...evem before it acts up she takes off hiding anf pacing circles around me...even more annoying! Someone please help!!
