Getting information on soundproblems

by joekamprad

Sometimes it is a puzzle to get around with a new soundcard, or getting a mix to work, I give some hints on getting information about devices and system here:

First check if alsamixer is enabled so you can use it as a simple source to solve most mute problems, and get a view of what is available:

Pulseaudio is used by default and here are some tools to solve the most common problems:

Configs are here: ~/.config/pulse/ and can easily reset by removing the files and log in again in the DE (rm -R ~/.config/pulse/) as a normal user.

Pulseaudio is started as a per-user service:

So as normal user:

systemctl --user status pulseaudio.socket

systemctl --user restart pulseaudio.socket

systemctl --user stop pulseaudio.socket

systemctl --user start pulseaudio.socket

Will give status / restart /stop and start for pulseaudio…


If the Mode is enabled, it can cause problems for multiple users:

It can be disabled by using alsamixer.

See http://superuser.com/questions/431079/how-to-disable-auto-mute-mode for more.

To save your current settings as the default options, run alsactl store as root.

HDA Analyzer to get direct hardware access to hda_intel cards:

This tool allows changing the HDA codec setting using direct hardware access
bypassing driver’s mixer layer.

To learn more about HDA (High Definition Audio), see
http://www.intel.com/standards/hdaudio/ for more details.

Please, if you find how your codec work, send this information to alsa-devel
mailing list – http://www.alsa-project.org .
