Hi Tom. Thanks for reaching out about this! I'm sorry you're running into issues with the sound system. We may be able to update the firmware. However, it would likely have to be done in your home, on your own network, as that could be part of the issue. We'd like to know some more about the speaker system and what exactly it's running into an issue with. To get started, you can either reach out to your local Best Buy store or contact us at (800) GEEK-SQUAD or (800) 433-5778.
