![]() ![]() ![]() Should you have trouble with a particular application, start it and find it on pavucontrol’s Playblack tab (Figure 5). The most likely setting you need will be High Fidelity Playback (A2DP Sink), which gives the highest quality sound. The tab should show your speaker, but sometimes it will not be turned on. As a last step for security’s sake, run discoverable off so your controller does not become a back door to your entire system.Īt this point, open pavucontrol and go to the Configuration tab (Figure 4). You will want your speaker to be trusted, because, unlike wired speakers, your Bluetooth speaker runs on batteries, and you probably do not want to have it on all the time. Finish with trust SPEAKER-ID so that the speaker is automatically paired when turned on, and your speaker is ready for use. When a pairing is successful, another audio cue is given, but use paired devices to check. Returning to the speaker, use the sub-command pairable on, quickly followed by pair SPEAKER-ID. Pairing may also be erratic for other reasons, so you may need several tries before you are successful. If you fail to pair the first time, one reason may be that you started the attempt to pair with too little time left to establish the connection. Usually, an audio cue tells you that the speaker is ready.) The speaker will be pairable for about two minutes. (In the case of my speaker, that consists of holding down the plus volume control at the same time as pressing a small button by the on button. To pair, consult the speaker’s manual about how to prepare it for pairing. Then use discoverable to get the speaker’s ID. Use the sub-commands list or show to learn the controller’s ID or copy it from a desktop tool. The first step is to prepare the controller. You could also use a user-friendly alias, if you have given the controller one: bluetoothctrl select Nandayįigure 3: The advantage of bluetoothctl list is that it gives detailed information about what it is doing. Sets the controller to the one with that ID. For instance, the command bluetoothctl select F4-F5-D8-E7-B5-AD bluetoothctl consists of the basic command, plus a sub-command, and, in places the device or controller ID. However, I recommend bluetoothctl for configuration (Figure 2), a command-line tool that breaks down tasks into smaller steps, so you can see where the problem lies (Figure 3). You can use a variety of desktop tools for configuration, including the tools provided by Gnome and KDE, or install blueman. ![]() Depending on the software you use, your computer can be identified as the controller or adapter, while the speaker device, for some arcane reason, is sometimes referred to as a headphone. To save time, you can also set your speaker as trusted, so it pairs automatically each time it is turned on, saving you time and repetition. To set up a speaker, you must pair it with your computer’s Bluetooth support, linking the two. Most, too, should support Linux out of the shrink wrap. Most dongles support Bluetooth 4.0, and many will support earlier versions. Low energy consumption dongles may have a limited range of a couple of meters, so the positioning of your speaker may affect your purchase. If Bluetooth is not running, you can buy a USB dongle for $5-40, depending on quality, range, energy consumption, and version. For instance, to start Bluetooth, use the command: systemctl start bluetoothįigure1: Bluetooth up and operating with music playing. You may need to reboot before your system is ready or to stop and restart Bluetooth and PulseAudio using systemctl (Figure 1). To check that Bluetooth support is enabled, run: systemctl status bluetooth In addition, install or update the following packages: bluetooth, pulseaudio-module-bluetooth, and pavucontrol, the GUI for configuring PulseAudio. At least in theory, this precaution can help you pinpoint where any problems lie. What follows is some of the basics, most of which applies to other Bluetooth devices as well.īefore configuring Bluetooth support, update your PulseAudio installation and check that it is still working. ![]() However, the stereo-quality sound of high-end Bluetooth speakers makes the struggle worth any audiophile’s time. Still another challenge is finding relevant online help. To be fair, part of the trouble is PulseAudio, Linux’s sound system, which can be a cantankerous application in its own right and does not play particularly well with Bluetooth, often ceasing to coordinate with the least change. Getting Bluetooth sound to work always reminds me of the bad old days when configuring every piece of hardware to function with Linux was a struggle. ![]()
