Solved! On our sanyo TV (only a few months old) my husband muted tv to listen to something outside, and when he unmuted it, no sound.

I have that happen sometimes on my Samsung tv. On it changing channels will usually fix it. I usually just do channel up or down then right back. May not fix your problem but easy to try.
