Waldecho 256b intro for Linux by dominikr ^ dSr Released@ROMA.EXE 2026 ---------------------- There haven't been many tiny Linux intros with sound in recent years - mainly because `aplay` got dropped from most standard installations. But we can just write our own static ALSA library... no external dependencies, all in 256 bytes. Featuring a 48kHz bytebeat, and a visualization of the audio to the framebuffer@1920x1080. This demo expects an ALSA-compatible soundcard at /dev/snd/pcmC0D0p. If it doesn't find one, it will try pcmC1D0p and so on. The soundcard must support 48kHz, 2 channel, 16bit signed audio (should be standard for any modern card). `waldecho-2ndsoundcard` will start from pcmC1D0p instead. Needs framebuffer permissions for the current user. Add them with "sudo usermod -a -G video $(whoami)". Then switch to the console with Ctrl-Alt-F2, log in, and run it. Exit the standard unix way with Ctrl-C. Special thanks to Nuclear for pointers in the right direction and testing.
