Some of these packages may install with others, so forgive any duplication – I wasn’t tracking when I did it last.

1) Install jack, cadence, ladish, lib64flowcanvas, lib64qtcore, lib64qtgui, qjackctl, calf, pulseaudio-module-jack.

2) Open qjackctl, Setup. My setup was as follows, yours will differ:

Interface: hw:MobilePre


###Qjackkit Options

On Startup:

pactl set-default-sink jack_out

Then Quit qjackctl.

3) Add yourself to the audio group as shown in the video.

4) Create this script, make it executable.


sleep 25

pulseaudio &


Add the script path you created to your Startup Application preferences – enable it, close then reboot.

5) Open Cadence, Configure, Driver, make sure the devices reflect the correct input and output as seen in the video.

6) Start JACK from Cadence front page., tab over to Tools at the top, select Claudia. If Pulse and JACK are both running, you’ll see your input,  PulseAudio JACK Source, PulseAudio JACK Sink and Hardware Playback. Use the video to learn how to add extras like Calf, OBS, etc to the left panel. Once added, you can start the apps in the left panel by clicking on them once, then right clicking to Start.

7) Once you have Calf, etc setup – save your Calf, OBS and Claudia configs to save yourself the hassle next time.

Linux Accessibility For The Visually Impaired - For The Record

Linux Accessibility For The Visually Impaired. I received a comment from Milton asking me about text to speech options in Linux. He also wanted to know what I recommended for audio dictation under Linux. The first option is indeed, using FoSS awesomeness. However the later relies on Google’s Web Speech API. Also, here is that article on controlling your mouse cursor with your webcam and no hands.

sudo apt install festlex-cmu festival xsel
cd /usr/share/festival/voices/english/
sudo wget -c
sudo tar jxf cmu_us_clb_arctic-0.95-release.tar.bz2
sudo ln -s cmu_us_clb_arctic cmu_us_clb_arctic_clunits
sudo cp /etc/festival.scm /etc/festival.scm.backup
sudo echo "(set! voice_default 'voice_cmu_us_clb_arctic_clunits)" >> /etc/festival.scm
echo "This is a test." | festival --tts

To create the script that you will map in your keyboard settings (see video):
