New files for running the FM receiver in Docker with audio output: - Dockerfile.gnuradio-audio: GNU Radio image with ALSA→PulseAudio bridge - libasound2-plugins for ALSA PulseAudio plugin - /etc/asound.conf configures ALSA to route to PulseAudio - docker-compose.fm-receiver.yml: Full FM receiver setup - PulseAudio socket mount for audio - USB passthrough for RTL-SDR (requires privileged mode) - XML-RPC port 8090 exposed for tuning control - Environment vars: FREQ_MHZ, GAIN - entrypoint-fm.sh: Builds and runs flowgraph at specified frequency - run-fm-receiver.sh: Helper script with usage instructions Usage: HOST_UID=$(id -u) FREQ_MHZ=107.2 docker compose -f docker/docker-compose.fm-receiver.yml up

# Run containerized FM receiver with audio output to host

# Usage: ./run-fm-receiver.sh [FREQ_MHZ] [GAIN]
|
|
# FREQ_MHZ: FM frequency (default: 101.1)
|
|
# GAIN: RF gain in dB (default: 10)
|
|
#
|
|
# Once running, use XML-RPC from host to retune:
|
|
# python -c "import xmlrpc.client; p=xmlrpc.client.ServerProxy('http://localhost:8090'); p.set_freq(107.2e6)"
