Does a person sin if he hears his family playing music from the television and receiver, which were set up and paid for not with his own money, and what is his duty?

It is not permissible to bring a worker to install a device if it is known that it will be used for unlawful purposes, as this constitutes aiding in sin and aggression, which is forbidden. Allah Almighty says: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." And whoever has done so must repent to Allah and remove whatever can be removed of the آثار (effects/traces) of the sin, and advise family members to abandon forbidden music. And whoever repents and strives to remove [the effects of the sin] will not be burdened by the sin of what remains of the آثار (effects/traces) of the disobedience.
