Interesting. That suggests the kernel is negotiating the audio at the
same time as the display signal. It also suggests that the same
negotiation does not occur if the TV is already connected when turned
on.
I think we'll need to test with other non-nvidia GPUs/drivers to see if
the problem persists, or if it's specific to the nvidia module.
