Just flashed the Linux optimized Amanero f/w, the hisses and cracking noises when changing channel 5 to channel 6 disappeared, which is very good! The Linux-optimized Windows driver is special. There is only 32bit to choose in the Windows driver panel while we could select 16 and 24 bits in the...

I think it is not only the grain is reduced but the output gain as well. Same to you I have to bump up my volume knob to compensate the new soft sound. Flashing the Amanero firmware is a bit easier since I do not have to open the top cover. I would try it later but I would worry that the DAC...

Hi DACLadder, I finally get this issue sorted: 01. Flashing the Altera R721 jic and the two original Xilinx jed to the DAC, then installing the Windows driver downloaded from Audio-gd website. Now the DAC goes back to its default state; 02. Then flashing the two latest 2021-Oct PLL-N...

It is already very late night here in my place so I would try the Altera FPGA R721SMD.jic tomorrow. I think it is ithe FPGA that controls the functionality of the DAC. I hope by retrieving the two Xilinx (IIS_pro.jed and R7_10m_clk_sel.jed) and FPGA (R721SMD.jic) back to their defaults my R7...

I now have original firmwares for the two Xilinx chips, but not FPGA. Would you have the original FPGA firmware for R7 MK2?

I flashed back the "IIS_pro.jed" to header "A", the front lcd panel displays the frequency as 48.0 regardless of what type of quality of music file I played on my Windows PC. The functionality of auto-sensing the sample rates of source file failed, and no sound coming out from USB as well. I...

Thanks for your prompt reply. You just lent me a big hand on this!

Hello I a newbie here. Nice to be joining such a big family of users of Andy-GD equipments here. I am an R7 MK2 owner. I was flashing the new 2021-Oct FPGA firmware to my R7 MK2 a moment ago. However, I plugged the cable to the wrong socket. The cable should have been plugged onto socket B but...

Hello my name is Julian. I' been visiting this forums for a few years now and wanted to be part of them. Thanks to everyone here. :relaxed: I am a user of Shanling M6 Pro 21 and Audio-gd DAC.
