Hi @hertsmacman,
Thank you for getting back to me.
I'm sorry to hear that you're not happy with your Hub 2. However, we have only recently released the Hub 4 which is not yet available nationwide. This Hub is only available in certain areas around the UK, and by looking at your account, unfortunately, it's not available in your area just yet.
Are you experiencing any connection or speed issues with your current Hub 2? We can only complete Hub swaps if there is a fault which we have diagnosed and identified. If you're experiencing any issues with your current Hub, I'm more than happy to look into this for you.
As for your TV box and sound issue. Have you taken a look at the link I previously provided?
Can you tell me if rebooting your TV box has resolved this issue? Have you checked your TV settings to ensure that there is nothing causing the sound drop out?
Please keep me updated on this.
Thanks.
