When no members follow up, it is usually because they're not experiencing the issue. I tried a bunch of channels, including the Food Network, and did not experience the issue. You could try clearing your caches, clearing channel data, rebooting your modem and router and doing an IPTV Reset. In fact, you might try an IPTV Reset first to see what that will do.
Depending on your add-on/app, there might be an audio delay setting you could tinker with in the audio settings, although this often has to be tweaked for each channel.
