■ Notes for PC ASIO Driver Users
If playback issues occur when using the PC ASIO driver with default settings:

-> Set the Preset Profile to Sync_Low or Sync_Lowest
-> Alternatively, try other profiles to find the optimal setting for your system
■ MTU Configuration for Using Jumbo Frames (sMS-2000 / sMS-1000SQ)
The following instructions describe how to extend the MTU value in order to use Jumbo Frames on the sMS-2000 and sMS-1000SQ:
1. First, verify that audio playback via Diretta works properly with the default MTU 1500 setting.
2. Go to System Config → Ethernet and set the MTU value to 4088 or 9014.
(This setting should only be used in a network environment that supports Jumbo Frames.).
3. Click Save & Reboot to reboot the system.
4. After rebooting, go to the Diretta Config page and configure the following:
-> Set the Diretta Target MTU value to the same as, or lower than, the MTU value set in the System Config page.
-> Set the Diretta External MTU value to match the MTU value configured on the Diretta Host device (such as a PC or another Eunhasu device).
5. Complete the remaining Diretta settings, save the configuration, start Diretta, and confirm that music playback works properly.
■ PC Diretta ASIO Driver Update
The updated Diretta 148_00 ASIO driver for PC is also released together with this update. ASIO with support for MS Mode3, installation of either WinPcap or Npcap is required.

■ Important Notice Regarding Eunhasu OS Compatibility
With this update, a new verification mechanism has been added to check whether the software is running on an official SOtM product.
As a result, Eunhasu OS will no longer run on Raspberry Pi or general-purpose PCs.
If you are using Eunhasu OS on a PC that was built or modified through SOtM and require Diretta functionality, please contact us in advance. We will assist you so that usage remains possible.
