Getting information while having sound issues

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…

Auto-Mute:

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.

Information and configuraion tool for PulseAudio:

pacmd – Reconfigure a PulseAudio sound server during runtime

  -h, --help                            Show this help
      --version                         Show version
When no command is given pacmd starts in the interactive mode.
pacmd list-sinks

will show info about connected output-input-devices

Some more tools:

wget http://www.alsa-project.org/alsa-info.sh && sh alsa-info.sh

will give you advanced info about the Soundcards + system and outputs an URL where the info is posted.

pactl list sinks

Lists your active devices.

speaker-test -c 6

The number needs to be changed to your situation.
