Music, sound, has gone from my computer.....AVG wanted me to pay more for another thing called custo

how do I get my sound back on…something happened when AVG repaired a lot of other computers for many other people, which they lost the sound.on…I tried and phoned them, but they want me to pay for another service…I already have three (3) paid for Tune Up, Performance Multi Device & Internet Security…Now something called Customer support or Help…I give up, anything time I phone they want more $$ for another product they want me to buy…very frustrating !!   does anyone know how to restore it ??
