Mutation does change frequency of alleles in a population

Say you have 50% A and 50% a in a given population
and just suppose that heterozygous Aa individuals experienced "mutation" and became aa.

That right there increased allele frequency for a and decreased allele frequency for A.

Overall, then mutation changes the allele frequency in a given population.
