Issues with recording sounds for clips

I'm not sure if this is the right place to post this, but has anyone else encountered an issue where your highlights wont record the sound from clips you are trying to make? Everything sounds fine and all while I'm watching a match. However, the moment I try watching a clip I made from said match, the little speaker thing in the client has a line over it and there is no sound in the clip. I've tried restarting my client and repairing it, but cant seem to find a solution =(
