Sound card on TV?

Question

TVs

Does the TV have a sound card? If there comes a digital sound via hdmi, and is output by the speakers connected to the tulips.

Answer 1

Yes.
And the video card, and the processor, and the memory ...
And all the crap is soldered to one "motherboard" and cannot be removed.

Answer 2

There is no card as a separate device.
There is a set of chips that perform different functions, located on the same board.
There is a DAC for analog audio output. It can be either a separate chip or part of the main chipset.
