Audiolinux V4 headless release notes

Version 6.1.0

1) Full system update

2) Kernel  linux-audiolinux-rt version 6.10.2 LTO

3) Menu 737

Improved Diretta memory play script 10 'DIRETTA memory play' (Audio extra menu)
Now is possible to select Diretta Target and use the seek option

In 8 'COPY/BACKUP current installation to another drive' (System menu) added a check that /mnt directory is not already mounted to some drive and will copy files only if the target destination drive is really mounted

Menu update will not change the list of applications with realtime priority used by rtapp and saved to /etc/rtpriority/rtapp.conf

In the option 13 'REALTIME PRIORITY configuration' -> 4) Configure IRQ priority you can add video card to the list of devices with realtime priority
This is not generally recommended, but you could try it if you are using for example NVIDIA Cuda for HQPlayer

Improved Ravenna audio over IP configuration
Added 4) Recommended system settings to 6 'RAVENNA/AES67 audio over IP installation' (Audio extra menu) with the following content:
0) If you have 2 Ethernet outputs, go to System menu ->  'NETWORK configuration (Bridge, DHCP, Static IP, DNS)', enable bridge and conenct one output to router and the other directly to Ravenna DAC
1) Disable rtapp and rtirqs in System menu -> 'REALTIME PRIORITY configuration'
2) If you have 2 Ethernet ports and the Ravenna DAC is connected DIRECTLY to one, you could enable rtnet in System menu -> 'REALTIME PRIORITY configuration' with a priority of 90
3) Disable Ethernet card Power saving in Expert menu -> 'NETWORK/USB power saving'
4) Activate Merging configuration in Expert menu -> 'NETWORK CARD configuration' taking off # in front of the corresponding lines
5) Examples of NADAC configuration with ravenna-alsa daemon can be found here:

Added Roon library and settings periodic backup to 9 'ROONSERVER backup' (audio menu):
1 - Select backup directory and default activation time
2 - Backup now
3 - Enable/disable periodic backup
4 - Restore
5 - Exit

Now is possible to set ENERGY value for intel pstate driver in 17 'CPU FREQUENCY SCALING (driver, governor, frequency, turbo)'

Added options
10 'DIRETTA memory play'
11 'DIRETTA memory play configuration'
to Audio extra menu
These options will install and configure Diretta Memory Player
While Diretta Host is sending your music to a virtual card, Diretta Memory Player will load your music files to RAM and send them to Diretta Target without using Alsa on the host
This approach could improve the audio quality but you will not be able to use your preferred player (including upsampling, convolution etc.) and the selection of files to be played it's not so easy
In alternative you can control Memory Player on Audiolinux with the Windows Memory Play Controller that you can download from Diretta site
Enabling Memory Player will disable automatically Diretta Host
Please be sure that Diretta target is running on your endpoint PC

Options for disabling Linux journal and watchdog temporarily removed in Expert menu
They could break systemd and d-bus with last systemd and kernel version

Since LMS is not working anymore the package logitechmediaserver-git has been changed to logitechmediaserver-bin
If you are using LMS you should install the new package with the option in Install menu
Previous logitechmediaserver-git is not removed. If all is working fine you can remove it with the command
sudo pacman -R logitechmediaserver-git
