* Add --music-output-device to route music separately from voice Music/media and TTS both play through --audio-output-device today, with no way to send them to different sinks. Add an optional --music-output-device (env MUSIC_OUTPUT_DEVICE) that the music player uses instead, defaulting to --audio-output-device so existing setups are unchanged. Wired through docker-entrypoint.sh and documented in the README and install docs. * docs: fix swapped Default/Description columns in env var table The MIC_VOLUME, MIC_AUTO_GAIN, MIC_NOISE_SUPPRESSION and AUDIO_INPUT_CHANNELS rows had their Default and Description columns swapped relative to the table header; fix the ordering and the 'Suppresion' misspelling. Also repair the UNMUTE_SOUND row, whose description was garbled and which was missing its closing table pipe. --------- Co-authored-by: Matthew Davis <fedoraproject@virtual.drop.net> Co-authored-by: Florian Asche <github@florian-asche.de> Co-authored-by: Omar Amin <65174210+omaramin-2000@users.noreply.github.com>
