Alex P 0be9dbcc6c Enable ALSA rate resampling for configurable audio sample rates ... Changes the audio subsystem from hw: (direct hardware access) to plughw: (plugin layer with rate conversion) to enable configurable sample rates. Changes: - Update ALSA build to include plug,rate,linear,copy plugins - Change device names from hw: to plughw: in C and Go code - Remove 48kHz hardcoding for HDMI audio output - Keep USB at 48kHz since hardware is fixed at that rate - Update all comments to reflect plughw usage Technical details: - hw: devices bypass all ALSA plugins and require exact hardware rate match - plughw: devices enable the ALSA plugin layer for automatic rate conversion - Hardware still receives at native rate (48kHz), resampling happens in userspace - HDMI can now use 8k/12k/16k/24k/48kHz, USB remains at 48kHz - NEON-optimized resampling provides good performance on Cortex-A7 Requires rebuilding ALSA library with updated plugin configuration.		2025-11-21 02:22:22 +02:00
