Calculate Linux uses the ALSA (Advanced Linux Sound Architecture) driver to handle sound output. ALSA is closely related to the Linux kernel, thus reducing hardware requirements and improving sound quality. If you need a more complex configuration, for example sound output via Bluetooth or using an additional web camera, you should rather use the cross-platform Pulseaudio sound server.
Choosing your audio server
Pulseaudio comes by default on a newly installed Calculate Linux system, but you can also switch to another audio driver. To do so, click on the "Audio" icon to run
You can also select the default sound card for ALSA in this window.
The same result may be achieved from the command line, with the
cl-setup-audio --audio alsa --card 0,0
* Configuring audio parameters... [ ok ] * Настройка аудио выполнена!
To list the available audio devices, run:
cl-setup-audio --card list
Default sound card: [0,0] HDA Intel PCH, ALC887-VD Analog * [0,1] HDA Intel PCH, ALC887-VD Digital [0,3] HDA Intel PCH, HDMI 0 [0,7] HDA Intel PCH, HDMI 1 [0,8] HDA Intel PCH, HDMI 2 [0,9] HDA Intel PCH, HDMI 3
Managing sound volume with ALSA
To adjust the sound volume in ALSA, you can use
qasmixer, a tool included in the package, or simply use the window manager's audio controls:
The same may be done in the command line with the
alsamixer tool that comes with :
Managing sound volume in Pulseaudio
To configure Pulseaudio, you can use
pavucontrol (PulseAudio Volume Control), a tool included in the package, or just use the regular sound controls:
