Today I bought a tritton ax pro 5.1, in the morning it was working fine but my 5 year old son has pressed a button which I do not and even he is also not able to recognize which was that button . The sound has vanished . Now I am not able to understand what to do whether I should call the company executive or not . but i must tell you it is not a warranty product . So they will charge me .Is there any suggestion from your side to correct this problem?
