Sometimes it is a huzzle 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 watch should be allways alsamixer as a simple source to solve most mute problems, and get a view what is aviable:
As we use pulseaudio by default choose the right tools to see if there is a problem:
- GTK GUIs: paprefs and pavucontrol
- KF5 plasma applet: kmix and plasma-pa
- Xfce4 plugin: xfce4-pulseaudio-plugin, pa-applet-git
Configs are here: ~/.config/pulse/ and can easy reset by removing the files and relogin to DE (rm -R ~/.config/pulse/) as normal user !
pulseaudio is started as 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:
Mode is may be enabled, this is causing such problems at the moment for multiple users:
It can be disabled 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 change 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 .
wget -O run.py http://www.alsa-project.org/hda-analyzer.py
change python to python2 in the last line of the skript that it looks like this:
aha my python skills are lame in a way
i forget i need to change last line inside run.py to python2 like this:
os.system("python2 %s" % TMPDIR + '/' + FILES[0] + ' ' + ' '.join(sys.argv[1:]))
and run it:
sudo python2 run.py
you can also use my download here with the fixed skript out of the box like this:
wget http://www.kamprad.net/Downloads/hda-analyzer.py && sudo python2 hda-analyzer.py
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.
