Cool. Do you expect to release a similar update for the X16?Changelog:
Looking forward to getting your feedback.
- Fixed the noise issue under some Linux based sources.
- Compatibility optimized.
- Sound quality reviewed.
- Reliability improved.
If you find the dropout on all the filters when using spdif, the problem should be from your signal source or cable. The optical, coax and AES shares the same signal path in circuit, if it is about filters‘ problem, you should get the same dropout on any of these 3 portsIn order to offer high quality filters, Gustard has chosen to develop its own filters using a DSP Analog Device SHARC chip. This solution integrates an anti-aliasing algorithm designed by Gustard, using a high-precision 64bit floating point system. Moreover, this algorithm has been optimized to work perfectly with ESS DACs and ensure the best possible sound quality.
this filter is causing problems
or clock
description
have testing, 2x gustard x26pro
they had almost the same problem
filter works ok on usb but runs spif on tv, are there dropout
tried all filters
if in researching it is done with a firmware it will be good
try to get the filter tested
maybe just one, bad batch of gustard x26pro
uses f2 firmware
Thanks for your feedback. The '24.5Mhz' is caused by some OS which will put XMOS into an unpredicted mode with random noises. We added some rules in F20 to avoid this situation and did a lot of tests.I upgraded to the F20 beta. My first thoughts are here.
X16’s firmware already fixed this problem.Cool. Do you expect to release a similar update for the X16?
Hi, I've same problem with DSD 24.5MHz false detection. Steps to reproduce:Thanks for your feedback. The '24.5Mhz' is caused by some OS which will put XMOS into an unpredicted mode with random noises. We added some rules in F20 to avoid this situation and did a lot of tests.
From your post, I saw you entered '24.5Mhz' again. Please try to repeat it and describe the detailed configuration and power on sequences of your system.
Thanks for your support and I think here is a better thread to discuss firmware with less unrelated information.
My Gustard X26 Pro is on f2.0 Beta firmware. It is directly connected to my amplifier. My source is Alpine Linux based PC based on Linux 5.10 kernel.Thanks for your feedback.

If want to make sure about that your setup doesn't trigger the noise problem (that actually all units have), you must crank up the amplifier's volume at highest or you have to use an amplifier that doesn't have an integrated preamp with volume control.I have been watching this thread with interest but have had no noise or dropout problems with my x26pro. When first powered up it always displays DSD 24.5 MHz but changes instantly when it detects actual input with no issues. I use it connected to a Technics ST-G30 music server with USB. I don’t have a clue what the Technics uses to operate the USB interface as it is proprietary and can only be operated remotely with its own music library management system. The good news is it works perfectly in my case. I also use the Gustard BT interface occasionally also with no issues. Great sounding DAC! Yeah, it does run a bit warm but not at a level I am concerned with in the moderate weather in the PNW. I will upgrade the firmware once it passes beta.
Can you describe how is the noise like? Is your system in the common listening volume(using DAC's volume or amplifier's volume)?(Or take a video?)My Gustard X26 Pro is on f2.0 Beta firmware. It is directly connected to my amplifier. My source is Alpine Linux based PC based on Linux 5.10 kernel.
With the sequence below, I'm always experiencing "DSD 24.5 MHz" and noise issue as before firmware upgrade.
1. Put X26 Pro in USB IN
2. Power Off X26 Pro and your Linux based source
3. Wait 7 hours (my sleep time)
4. Power On X26 Pro
5. Power On your Linux based source
6. Watch the X26 Pro screen
7. See the "DSD 24.5 MHz" on screen when your Linux source gets booted
8. Listen X26 Pro's outputs with an amplifier and notice the existence of the noise
The noise is same as what it is before. It is like high pitch white noise. New firmware didn't affect on noise character...I don't know why you are still asking this??Can you describe how is the noise like? Is your system in the common listening volume(using DAC's volume or amplifier's volume)?(Or take a video?)
I have discussed with our firmware engineer. 24.5 on display is common for most Linux devices. Last update is trying to fix the noise in normal listening volume.
I tested on my Raspberry pi, got 24.5, but did not notice the noise(with full volume on X26Pro and amp).
Disregard this question. User error. All is well with I2S.New X-26 Pro owner here. Question for Gustard . Not firmware related but I have your U16 but apparently the I2S output of it cannot be used with the X-26 Pro I2S input. I tried 2 HDMI cables but the X-26 Pro will not detect the output of the U16. Is there a particular reason why they are incompatible with each other using I2S? Seems odd the X-26 Pro being the newer product would be designed not to be able to use the U16 I2S.
A strange thing happened yesterday. As I listened, I heard the noise of a disturbing wave starting slowly and increasing more and more and then decreasing. It happened while I was listening to the dsd. What can it be? I updated to F20 firmware. I'm connected via usb to a RPi4 as Roon Endpoint and via xlr to a Gs-x mini headset amp. ThanksChangelog:

вот у меня тоже самое ...Вчера произошла странная вещь. Когда я слушал, я услышал шумную волну, начинающуюся медленно, усиливающуюся все больше и больше, идущей медленно. Это случилось, когда я слушал dsd. Что это может быть? Обновился до прошивки F20. Я подключаюсь через usb к RPi4 в качестве конечной точки Roon и через xlr к усилителю мини-гарнитуры GS-x. Спасибов
