david d239d58c44 onboard audio: JMISC HPH wiring, UCM fix, update scripts for git deploy 2026-06-23 21:25:51 -07:00
david f1b65eb4d9 fix led-matrix-viz: use select.poll() instead of settimeout, fix hang 
The O_NONBLOCK flag set by setblocking(False) was not cleared by
settimeout(n) on this CPython/kernel combo, causing recvfrom to never
return data. Switched to explicit select.poll() with frame-interval
based timeout — simpler, more portable, and avoids the O_NONBLOCK trap.

Also fixes midi-bridge: add time.sleep(0.01) in no-data paths to
prevent 100% CPU spin from spurious POLLIN on f_midi rawmidi.
