What doesn't work about it? Do you have the Symbolic Toolbox which contains that function?

syms x
x= -vpasolve(sinc(x) == 1/sqrt(2));
Was useful for me asawell. In this case, x has both positive and negative solutions and i wanted the positive one (therefore the - sign)
I used your solution first and gave me this so thank you !
