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
Pulseaudio is used by default and here are some tools to solve the most common problems:
Configs are here: ~/.config/pulse/ and can
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…
If the Mode is enabled, it can cause problems for multiple users:
It can be disabled by using alsamixer.
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 to
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.
Change the last line inside run.py in python2 so it looks like this:
os.system("python2 %s" % TMPDIR + '/' + FILES + ' ' + ' '.join(sys.argv[1:]))
and run it:
sudo python2 run.py
you can also use my download here with the fixed script 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.
pactl list sinks
