16 bit RGB565 colors in dvi_out_hstx_encoder example and enable sound

[fhoedemakers]

Does anybody know how to use change the example in https://github.com/raspberrypi/pico-examples/tree/master/hstx/dvi_out_hstx_encoder to display an image in RGB565 in stead of RGB332.

I was asked to change the Pico-InfoNes NES emulator to work with HSTX. I have an Adafruit Metro RP2350.

The test repo can be found here:
https://github.com/fhoedemakers/pico-infonesFB/tree/HSTX
This is a version without menu or sd-card support. Roms must be compiled into the .uf2

It works but only with 8 bit RGB332 colors . There is also no sound, which comes to my second question, how can i enable it for sound?

This is probably the sort of question you should be asking at https://forums.raspberrypi.com/viewforum.php?f=143

I suspect that the example you're referring to is using HSTX to output DVI, which (unlike HDMI) only supports video data, not audio data.
