We’ve tested it with the following settings,
– Set Network speed 1Gbps(when set the Network speed 100Mbps, it had an issue, so it should be tested with 1Gbs.)
– Enabled the latency tune
– Used Roon ready. (When used the app such as required faster processing like LMS, MinimServer, BubbleUPnP Server, it requires high frequency. When used the app such as Roon ready, MPD, HQplayer, Shairport, LibreSpot, Squeezelite(not LMS) , they would work with this setting environment. .
– And the kernel version no. is 6.1.60-211(it’s currently in our beta server)

Result.
– The unit works upto 312Mhz, it becomes slow, but no problems for operations and playback.
– But the frequency set below 312Mhz, the unit itself became slower so even accessing to the web gui is difficult. There is 144Mhz set available when set below 312Mhz CPU frequency, but this 144Mhz selection has an issue such as when trying to accessing to the Web gui or doing other tasks while playing music, it’s impossible to do it, so 144Mhz set option will be removed in the next upgrade.

Conclusion.
– When tested with 312MHz, we can achieve the best sound quality. Compared to the default setting, we can proudly say the sound upgrade with CPU frequency settings is more than twice. Considering the price of the product, it was good enough before, but if you set up CPU FREQUECY, then I would say it is the best value for money.

By following multiple user’s feedback, when used MPD/DLNA function, 528Mhz frequency is recommended rather than using 312MHz. 312Mhz selection can bring abnormal functional issues to the device.

Eunhasu firmware version number 0.5.51 is released officially.

 

Version: V0.5.5
– Date: 11-24-2023
– Added ‘CPU frequency’ selector.
– Added ‘Set Max volume’ button.
– Updated eunhasu, smb avahi services.
-Disabled unused avahi service(nfs).
– Changed a few GUI texts.
– Fixed up ‘Start with Logitech Media Server’ bug.

 

CPU Latency tune and CPU frequency functions can improve sound quality by changing CPU and OS settings.
This feature is only available with the latest version of Eunhasu firmware and the latest kernel versions, and supported on Intel series CPUs such as sMQ-Q370.

 

– CPU Latency tune
The biggest function of CPU Latency tune is that it improves sound quality by controlling CPU operation and OS functions.

When this function is turned off, like other general OS settings, when the CPU does not need to be operated, the CPU settings are changed to operate slowly or stop operation to reduce power consumption. If the CPU operates slowly or stops and the CPU needs to operate quickly again due to processing, change the CPU’s frequency and settings to enable it to operate quickly again. However, during this operation, the operating frequency and voltage of the CPU change, and the CPU’s response to certain processing (latency) becomes slow, which reduces sound quality.

If you turn on CPU Latency tune, the CPU will wait for content to be processed without changing the CPU’s operating frequency and voltage even when it does not need to operate. Additionally, when something needs to be processed, it can be processed immediately without having to change the operating frequency and voltage of the CPU, so the CPU’s response (latency) becomes very fast and the best sound quality can be maintained.
To change this setting, you must reboot Eunhasu for the setting to take effect.
For the best sound quality, we recommend always turning it on.

 

-CPU frequency
* Performance: Automatically controls the operating frequency and turbo boost function of the installed CPU.
* Frequency : Set the CPU frequency.
* Frequency + turbo: Turns on the CPU’s basic maximum frequency (base frequency) and turbo boost function, and if necessary, the CPU’s frequency is automatically controlled up to the max turbo frequency.
* Frequency only: Operates the CPU at the selected frequency. The turbo boost function is turned off and a constant frequency is always maintained.

 

If the frequency setting is too slow, the CPU may not be able to process the required processing quickly, which may cause problems with music playback. Therefore, you must test to set the frequency to a problem-free frequency.
It is recommended to set it to 50 to 80% of the CPU’s maximum speed, but depending on the PC situation, it may operate without problems at lower frequencies and sound quality may be improved.

 

The updated kernel version no. is 6.1.60.

Thank you!
