Does anyone have experience with any of the recent RP2040 or RP2350-based boards that have DVI/HDMI output, a USB host port or ports, SD card slot, and audio? These boards are often used to run retro computer emulators. I'm particularly interested in the quality of the audio output, and whether anyone has been able to use that feature from Rust. Pinging @raph in particular, who wrote this HN comment: https://news.ycombinator.com/item?id=44883045

@matt@toot.cafe i just got a http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-5-Ultra.html for use as a media centre and the audio quality us great. Previously I had a Radxa RockPi4b+ and its audio was fine too. I never used Rust with them tho.

Damn, the most promising-looking board (https://www.adafruit.com/product/6200) is out of stock. The Olimex RP2350pc (https://www.olimex.com/Products/RaspberryPi/PICO/RP2350pc/open-source-hardware) is in stock, but it mentions PWM stereo audio generation, and my first Raspberry Pi project over 10 years ago taught me to hate the original Pi's PWM-based audio. Though that page _also_ mentions an audio codec, so I don't know if the PWM audio is all there is or just one of two options.

Yes, I'm itching to do an embedded Rust project on bare metal. Even Linux is too complex for my tastes these days. I think the growing complexity of modern software, as epitomized by the generative AI craze, is making me want to run the other way.
