It's a know bug existing in some E2 based boxes. You can try to change channel instead of working around HDMI cable ...After a reboot, for example, lost the light, the picture shows, but no sound. Helps only disable HDMI cable from Solo.
Switching to another channel does not help ...

Can you tell us on which type of TV you have noted this problem ??
I have similar problem with BH 1.7.2 in Vu+ Duo and Pioneer PDP-LX 5090. HDMI-CEC is enabled and I haven't checked if disabling it has an effect. In my case the problem goes away simply by changing channel so no biggy.
same problem for me. after reboot no sound. sometimes switching to other channel works. sometimes i must restart the box.
NB: this mainly appears in meoboot
