- ALSA Utilities
Install thealsa-utilspackage. This contains (among other utilities) thealsamixerandamixerutilities.
pacman -S alsa-utils
- Unmuting the channels
ALSA by default has all channels muted, all of which will need to be unmuted manually. This can be done using amixer:
amixer sset Master unmute
This can alternatively be done using alsamixer:
alsamixer
- Test your changes
speaker-test -c 2
- User privileges
Usually, local users have permission to play audio and change mixer levels.
To allow remote users to use ALSA, you need to add those users to the audio
group.
