NAME¶

bluealsa-aplay - a simple bluealsa player

SYNOPSIS¶

bluealsa-aplay [OPTION]... [BT-ADDR]...

DESCRIPTION¶

Capture audio streams from Bluetooth devices (via bluealsa(8)) and play them to an ALSA playback device.

By default bluealsa-aplay captures audio from all connected Bluetooth devices. It is possible to select specific Bluetooth devices by providing a list of BT-ADDR MAC addresses. Using the special MAC address 00:00:00:00:00:00 will disable device filtering - the same as the default behavior.

OPTIONS¶

-h, --help

Output a usage message and exit.

-V, --version

Output the version number and exit.

-v, --verbose

Make the output more verbose.

-l, --list-devices

List connected Bluetooth audio devices.

-L, --list-pcms

List available Bluetooth audio PCMs on connected devices.

-B, --dbus=NAME

BlueALSA service name suffix. For more information see --dbus=NAME option of bluealsa(8) service daemon.

-D, --pcm=NAME

Select ALSA playback PCM device to use for audio output. The default is “default”.

--pcm-buffer-time=INT

Set the playback PCM buffer duration time to INT microseconds. The default is 500000. ALSA may choose the nearest available alternative if the requested value is not supported.

--pcm-period-time=INT

Set the playback PCM period duration time to INT microseconds. The default is 100000. ALSA may choose the nearest available alternative if the requested value is not supported.

--profile-a2dp

Use A2DP profile (default).

--profile-sco

Use SCO profile.

--single-audio

Allow only one Bluetooth device to play audio at a time. Without this option, bluealsa-aplay plays audio from all selected Bluetooth devices. Please note that playing from all Bluetooth devices at a time requires used PCM to be able to mix audio from multiple sources (i.e., it can be opened more than once; for example the ALSA dmix plugin).
