  Well… sometimes things don’t go exactly as planned and in the software world that is often the case, now that AV Linux 2020 has been out for a while some known issues have come to light so here is some information in case you’re affected..

Issue 1: Some Users have reported PulseAudio doesn’t connect to the Audio hardware or takes its sweet time to connect.. A Google search of this problem yields quite a few hits especially with Ubuntu users so this seems to be a known PulseAudio problem affecting some systems and not necessarily specific to AV Linux.. What happens is, if you boot into a session the PulseAudio applet on the panel displays with an ‘X’ which means it’s muted and a notification tells you “Establishing connection to PulseAudio. Please wait…”. Some people report that it doesn’t connect at all, some report that after a minute or two it connects and others report that on a reboot it works as expected with no further issues.. The problem seems to be with PulseAudio writing it’s config files in $HOME/.config/pulse and since it occurs elsewhere and doesn’t affect everyone the only ‘fix’ I can suggest is to try rewriting the pulse folder and files by opening a regular Terminal and using this command:

mv ~/.config/pulse ~/.config/pulse.old

Then restart PulseAudio’s sound server manually with this command:

pulseaudio --start

Issue 2: This is a big one…literally! AV Linux uses Systemback to create it’s bootable ISO files and to copy (install) and uncompress the Live ISO filesystem to your hard drive. The original developer of Systemback ceased development almost 4 years ago and as time has gone on more and more people with newer computer systems are needing support to install to NVMe SSD drives which Systemback didn’t support… just before AV Linux 2020 was released a User tipped me off to a fork of Systemback that now supports NVMe drives, of course I was ecstatic to see the NVMe problem solved just like that! Well… the good news is NVMe installs work, the bad news is that this fork of Systemback has a bug that seems to install AV Linux to NVMe and all types of hard drives as expected but it installs both the usual way to the User selected HDD partitions and it also additionally seems to retain the Live filesystem in a “/lib/live/mount” folder and copy it to the Users hard drive. Now “/lib/live/mount” is a necessary folder on the Live ISO but it is not necessary at all on the installed system so in effect Systemback is double-installing the AV Linux filesystem in 2 different locations which is not harmful or detrimental in any way to performance but it makes an install take up much more hard drive space than it should with a copied over useless folder containing the entire filesystem! A few Users had reported surprise at how large the installed filesystem was and one User did the homework necessary to identify the problem (thanks Dan!) So despite this annoying new issue let me reiterate it does no harm to your system and is quite unnoticeable in daily use but of course who wants Gb of wasted space on their HDD!? The solution is brutal but simple, we simply need to remove the useless /lib/live/mount folder which can be done in 2 ways… The simplest way is to open a Root Terminal and issue the following command:


rm -rf /lib/live/mount

Deleting the mount folder and contents may take several seconds…For those who don’t feel comfortable issuing a Root command and want to click a button I have made an updated AV Linux Assistant that will do this with a button, this updated Assistant also will install “winetricks” and provide a button to run it for those who want to further customize Wine-Staging as a newly added feature as well.

The updated AVL Assistant is here:
















*ADDENDUM: An updated 1.9.4 version of Systemback which fixes this issue has been provided (Thanks Franco Conidi!). If you’ve deleted the folder referred to above and wish to use Systemback to make your own customized ISO or for it’s backup capabilities then you will want grab it and install it. Download the ‘tar.gz’ folder and extract it, run the ‘’ script as Root and follow the terminal prompts and it will upgrade Systemback to 1.9.4.

Issue 3: The ‘EQ10Q’ plugins don’t display their GUI’s in Ardour… Ugh, this is a long running issue that results from the EQ10Q Plugins being compiled with a different GTK2 version than the one in Ardour.. This type of persistent issue is the reason that many developers of Linux Audio plugins are abandoning Desktop toolkits (GTK 2,3 and QT) and using much more compatible X11 libs to create Plugin GUI’s. To obtain a set of these plugins that will work with Ardour is is necessary to uninstall the existing ‘eq10q’ package with Synaptic Package Manager and then go to the EQ10Q Website here:



These may not be the only issues in AV Linux 2020 but these are the most currently prominent ones, more may be added to this post in the future…

AV Linux 2020.4.10 RELEASE NOTES!

AV Linux 2020 DesktopAV Linux Software DemosCinelerra-GG Video Editor

  Shortly after the Christmas holidays some time opened up for me to work on an AV Linux update and as time went on the rumours about a new respiratory virus started to permeate the mainstream media and now here we are in the middle of a worldwide pandemic! So it is with mixed feelings but much gratitude I release the latest ISO of AV Linux 2020. I am very thankful for the multitudes of talented developers and collaborators from all over the world whose incredible work I get to present and share on this little DVD-sized serving platter, my compliments to the chefs!! It occured to me recently that with the exception of Ubuntu Studio and perhaps the CCRMA project AV Linux is the longest running Linux Audio Distribution out there, As with many DIY spare time projects there have been times of ebb and flow and even a few times when continuing seemed to be impossible but I have to say the odds were never great for a Canadian farmer to pull this off in the first place and it’s still here!

  Unlike older versions of AV Linux this LiveISO is not aiming to provide an everything-but-the-kitchen-sink experience, running Linux Distros live off thumbdrives is fun but in the real world nobody is going to spend a sustained amount of time using any Operating System to it’s full potential from a USB Key… what’s possible isn’t necessarily practical. The idea here is to focus on a fast, efficient and attractive base and complement it with strong front-running applications to showcase good performance and reliable software with an eye toward practicality and economy. Ardour and Mixbus32C are great included DAW examples but what makes AV Linux a good platform for Ardour also makes it a good platform for Qtractor, Reaper, Bitwig, Renoise, Waveform or whatever DAW you prefer. For those not experienced with Linux Audio the intention is to answer your questions before you know to ask them and provide most of the laborious ‘next steps’ that would be required if you were to start with a basic vanilla Linux Distribution and configure it for the best Audio performance.

  For those who may doubt the seriousness or potential of such an independent homespun DIY project to be of any value I ask you to to simply try it and see, download it, copy it to a USB Key with Unetbootin and boot it. Read the User Manual (the only one of its kind in Linux Audio) and hopefully you will see that the countless hours invested in curating, compiling, maintaining and ‘fixing problems you didn’t know you had yet’ since 2007 have some merit and will provide you with a fast, productive and powerful platform to create top shelf multimedia content that can go toe to toe with any platform out there…

Now go create a masterpiece!
