Changed default system time service from systemd-timesyncd to the more powerful chronyd
For more information:
https://wiki.archlinux.org/title/Chrony
'Chrony is a versatile and powerful time synchronization tool for Linux systems. It combines the functions of a client and a server, allowing for synchronization with external time sources while also serving as a time server for other systems. This feature is advantageous in environments where maintaining a local time server is preferred or necessary'

Isolated core script will now update each time the list of available Audio applications

When Diretta host is enabled, Diretta Memory will be automatically disabled
In INSTALL/UPDATE menu you will now be notified if the application was not really installed becuase of errors
In that case contact support
The packages gssdp gupnp gupnp-dlna gupnp-igd rygel are no more 'on hold' since last HQPlayer version needs the last version

Fixed option 12 'SUPPORT logs' in Main menu changing transfersh with a python script supporting WeTransfer

FIX Qobuz or Tidal streaming using JPLAY iOS with HQPlayer:
Go to console/terminal and type
sudo bash /opt/scripts/update/jplayfix.sh
and reboot

Fixed the problem that acpi-cpufreq was correctly set but not enabled after a reboot with AMD CPUs
Updated camilladsp gui configuration. You should re-configure camilladsp with the option in Audio extra menu
HQPlayer embedded installation will re-compile libgmpris library

Web Interface 1 (wetty) disabled because incompatible with last nodejs
Otherwise wetty will produce a lot of coredump files in /var/lib/systemd/coredump/ that could fill your installation drive
Moreover it was a security risk and last upstream version is not working
Please use ssh audiolinux@ipaddress (recommended) or the other Web Interface at ipaddress:5001

General cleaning of special update scripts

Ravenna installation script (Audio extra menu) will modify /opt/ravenna-alsa/merging_ravenna_daemon.conf
during installation using /home/audiolinux/.config/alsa-aes67-driver/butler.config as path for daemon configuration file

Removed package tracker3 to avoid errors during system update

Updated various scripts and files for compatibility with last versions of HQPlayer

Improved Diretta scripts in Audio extra menu are now compatible with Diretta salsa
If you are using Diretta you should update the packages diretta-alsa-daemon, diretta-alsa-dkms, diretta-memory-player if installed and reboot
The new diretta-alsa-daemon is using the systemd service diretta_alsa instead of diretta_alsa_single and it should be changed automatically with menu update if enabled

Fixed option 22 'DELAY audio service' in Expert menu
(roonserver delay)

The option Audio extra menu -> 11 'DIRETTA memory play configuration' -> 1) Install/update will now compile Diretta Memory Player instead of installing the pre-build binary
With this change the player will be compatible with all versions of Audiolinux

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

Improved Ravenna audio over IP configuration

Added options
10 'DIRETTA memory play'
11 'DIRETTA memory play configuration'
to Audio extra menu

Option for disabling Linux journal removed in Expert menu
They could break systemd and D-bus with last systemd and kernel versions

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:
https://www.audio-linux.com/images/ravenna1.png

6) Merging documentation:
https://merging.atlassian.net/wiki/spaces/PUBLICDOC/pages/4817173/RAVENNA+ASIO+recommended+Network+Adapter

Added Roon library and settings periodic backup to 9 'ROONSERVER backup' (audio menu):

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

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
