The Jamulus OS v2.00 with Jamulus 3.6.0 is out. It is based on ubuntu studio 20.04.1 and runs XFCE4.
Some script to optimize ubuntu studio env for Jamulus have been added.
Ardour 6.3 replaces ardour 5.12.
ulauncher has been added and a list of applications have been added to default (RaySession, vokoscreen ...)
Attention, the iso file size is greater than V1 size because compression is faster.
Some boot startup option have been added. The default target does not check the iso image.
First time you run your JamulusOS
Go to Ubuntu Studio Controls and click on "Fix Realtime permissions" which is in red if not yet done.
Once done logout of the X window session and login again.
CTRL+ALT+t : open a terminal CTRL+ALT+e : open text editor CTRL+ALT+w : open web explorer CTRL+ALT+m: open task manager CTRL+ALT+d : display desktop or restore applications CTRL+space : display ulauncher CTRL+ALT+L : lock screen CTRL+ALT+DEL : Change current user CTRL+ALT+HOME : Display previous desktop CTRL+ALT+END : Display next desktop
Audio Mixer
In order to access the ALSA mixer to increase/decrease volume of your headphones for example if you have no physical knob to do it. (You can also use QASMixer from UbuntuStudio Controls which is more convenient to use).
KEYS:
UP : increase volume
DOWN : decrease volume
LEFT : go to the channel on the left
RIGHT : go to the channel on the right
m : toggle mute channel
CTRL+ALT+talsamixer
You might want to create an application shortcut for alsamixer on your desktop.
Bluetooth
I tested successfully bluetooth connection with an ios and an android devices. I could send for example, iRealPro application audio to Jamulus and jam along on a Jamulus server by redirecting pulse_out to Jamulus using qjackctl.
How to start Jamulus (JamulusOS v2.00) ?
Step 1/ Set Ubuntu studio controls settings. Step 2/ Check qjackctl audio connections. Step 3/ Start Jamulus and connect to a server.
If you don't use pulseaudio to grab audio from web explorer like firefox or other pulseaudio capable applications, please don't activate the pulseaudio bridge in Ubuntu studio controls as it can take CPU even if you don't use it.
If you have a simple setup with Jamulus, you will not need pulseaudio bridge, so don't activate it (click on "remove input bridge" et "remove output bridge" buttons if any in Pulse Bridging tab and then click "Apply audio settings," | all in Ubuntu Studio Controls)
Close all applications that you don't need especially web browser which can take a lot of CPU/RAM ... So it can slower your computer if you have not enough resources !
Hi,
I followed your installation instructions as per https://sourceforge.net/projects/jamulus-os/files/JamulusOS/v2/.
I used this procedure to make the live USB: https://ostechnix.com/how-to-create-persistent-live-usb-on-ubuntu/.
I got stuck on this point of your installation procedure:
"4. Reboot your computer and select your usb drive/stick in the boot options menu. The computer boots on the USB drive/stick. (Select "Try Jamulus OS without installation" in the grub menu)".
In the GRUB, I have:
"Jamulus-v2.00-EN-dvd-amd64.iso - persistent live
Jamulus-v2.00-EN-dvd-amd64.iso - persistent live
Jamulus-v2.00-EN-dvd-amd64.iso - persistent live
Jamulus-v2.00-EN-dvd-amd64.iso - persistent live
Jamulus-v2.00-EN-dvd-amd64.iso - persistent live
Jamulus-v2.00-EN-dvd-amd64.iso - persistent live
Memory test"
Whichever option I select, I get
"error: Can't read kernel (hd0, gpt4)/casper/vminux.
error: you need to load the kernel first.
Press any key to continue..."
And when I do, I come back to the above GRUB list.
Help! Please tell me what I am doing wrong.

1st, thank you Laurent for this update, and for an elegant potential solution for folks who want to evangelize or just want to kick the tires of Jamulus.
Using mkusb-dus from Debian "Buster" and and md5sum-confirmed download of the 2.0 .iso onto an 8GB thumb drive, I get "symbol grub_calloc not found" and then a grub-rescue prompt on boot. I have no problem booting from USBs from the previous release.
Have you seen this, or have any suggestions to help me troubleshoot?
Thanks for any light you can shed, and again thanks for this update.
=tew=
P.S. Sorry. This time I burned the .iso as a "persistent" image/os. Could this be part of my problem?

The only thing i can think of (if you use defaults to all options using mkusb) is that your thumb drive is tired and contains corrupted sectors or try to update your mkusb if it is not last version ...
Persistent image/os is OK, it is aimed to be use in persistent mode as well as hard drive install.

I think that was it. I just wiped the USB and tried again. It was new, but came with backup software installed on it. Jamulus OS now boots up fine on an old Acer laptop and a Core 2 duo tower.
Thanks again, Laurent.

You were right, the iso file was not properly downloaded. In fact, I encounter issues when downloading: it fails when it reaches approximately 2GB. And, download speed rate is depressingly low though my internet connection is cabled. I'll get back to you when I've managed to get this iso file on my computer.

Jacques
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
There is no torrent but you can try to click "Problems downloading" button when clicking on iso file to download and select a mirror site to download iso from.
Please note that you will perhaps need an NTFS file system if your are on windows. I'm not sure it will download successfully on a FAT32 file system.

Hurray! I finally managed to download the iso file this morning. I believe it was simply a download speed rate issue because it's the only thing that changed from my previous trials.
I got JamulusOS running on a liveUSB and opened a Jamulus Client session.
I did this with Ubuntu 20.04 on Lenovo Thinkpad 470.
Thanks for your support,

As you can start jamulus OS on usb, can you choose at boot time, the option "try Jamulus OS without installing but check filesystem*? If yes, then select the option. Messages will appear saying it checks the iso file and say if it was a success or not.

Well, sorry for my bad explanation... I got very good experience with the Jamulus OS starting from USB (works fine with my band, we tried several times), e.g. I got about 10 ms less overall delay than with Windows (same hardware). But now I decided to install the Jamulus OS to my harddisk in order to get better system performance. So I can say, I have no problems using Jamulus on Linux (and all the other neccesary stuff like Qjack and so on). But I'm not familiar with the use of Linux itselve, which makes it difficult for me to handle the system problems... Sorry for the inconvenience., and thx for your patience...

It is a seperate, internal SSD 1TB. It's the same as the windows SSD. I dismounted the windows in order to have a clean PC with an empty SSD for installation. Than I startet Jamulus OS installation via USB. This went well... Restarted and landed on this "Minimal BASH-like line editing is supported..."
So to answer you last question: Yes, I mounted by myself (works with all Windows System) and no, this is the only HD mounted in the pc at the moment.
I did the "Jamulus without installation but check filesystem" getting the message "check finished, no errors found."

Hello Jacques-Olivier,
Did you check iso consistency with md5 ? (It is useful to verify that downloaded iso file is not corrupted.)
https://help.ubuntu.com/community/HowToMD5SUM
For Linux:
The two displayed lines must be the same.
Jamulus-v2.00-EN-dvd-amd64.iso and Jamulus-v2.00-EN-dvd-amd64.md5 are files available in download section.
Which mkusb-dus version did you use ? (dus version)
If you have a doubt on the options to select just hit the "Default" button to all options.
I will make test on my side to check if i have the same behavior after downloading the iso file from sourceforge.
Last edit: Laurent Schwartz 2020-11-14
(I added some informations in the previous post so please check the forum message).
I tested succesfully the downloaded iso file on my Dell Inspiron 1525 (2009).
Another question Jacques-Olivier, are you trying to start JamulusOS on a 64 bits PC ?
Hi Laurent
V2 all good, works well with old Acer laptop, and now works on a new Dell laptop that blocked V1 in BIOS with security issues that I was unable to fix.
