Hi Jasonmcbride,
Welcome to Sony Community!
Do you still remember when was the last time that it worked? You may refer to this link to troubleshoot the issue, https://us.en.kb.sony.com/app/answers/detail/a_id/33256/p/48903%2C49902%2C71454%2C71497/c/65%2C66/kw/no%20audio%20when%20connected%20to%20the%20tv%20via%20hdmi
We highly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/ to assist you with this issue.
