help

  • 1.4
    Usage:
      bluealsa [OPTION]...
    
    Options:
      -h, --help		print this help and exit
      -V, --version		print version and exit
      -B, --dbus=NAME	D-Bus service name suffix
      -S, --syslog		send output to syslog
      -i, --device=hciX	HCI device to use
      -p, --profile=NAME	enable BT profile
      --a2dp-force-mono	force monophonic sound
      --a2dp-force-audio-cd	force 44.1 kHz sampling
      --a2dp-keep-alive=SEC	keep A2DP transport alive
      --a2dp-volume		control volume natively
    
    Available BT profiles:
      - a2dp-source	Advanced Audio Source (SBC)
      - a2dp-sink	Advanced Audio Sink (SBC)
      - hfp-hf	Hands-Free (v1.7)
      - hfp-ag	Hands-Free Audio Gateway (v1.7)
      - hsp-hs	Headset (v1.2)
      - hsp-ag	Headset Audio Gateway (v1.2)
    
    By default only output profiles are enabled, which includes A2DP Source and
    HSP/HFP Audio Gateways. If one wants to enable other set of profiles, it is
    required to explicitly specify all of them using `-p NAME` options.
