Default [Q] no sound sghi747

i flashed to hyperdrive rom on my samsung galaxy s3 for at&t. it did nothing but boot loop. i checked md5 sum ten times had my brother check it also. re downloaded via charter high speed. still boot loops. i decided to run slim bean android 4.4 rom. it loaded flawlessly. BUT i have 0 speaker sound. i have tried everything to get sound to no avail. does anyone have any ideas why i wouldnt have sound?
