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.
