To debug audio problems, I access the Linux command line via '''ssh''' and use some command-line utilities to test and configure.
The Linux audio system is called ALSA. You can install '''alsa-utils''' to get some command line tools for testing/configuring audio. Unfortunately, ALSA and Linux audio configuration is complex and hard to figure out.
Install those utilities by giving the command:
sudo apt-get install alsa-utils
Here’s some documentation on ALSA http://www.linuxfromscratch.org/blfs/view/cvs/multimedia/alsa-utils.html1
One command I use is '''speaker-test'''. This will cause your audio device to make tones, if everything is properly configured.
Making audio devices work in Linux can be complex and frustrating. Here are some more tips:
Use this command to list the audio devices that the system knows about:
Login to the console using ssh from another computer. see [[Accessing_Zynthian_from_your_computer]]
Use the following command to list the audio devices that the system knows about:
aplay -l
aplay -l
alsamixer
alsamixer
followed by the Enter key in the terminal/console.
(followed by the Enter key in the terminal/console.)
