I have not heard any of the clicks I was hearing on the 4.19 RT kernel. I thought that the kernel bug was in 4.19.xx and later. https://github.com/raspberrypi/linux/issues/3204 I am pretty sure that the 32bit kernel had the problem also. I will SSH into my other device and load this kernel up on my Kii Three system to test there. My Audio Systems Link to comment

If the driver from ASIX that works with ARM doesn’t use usbnet I wonder if it is just the source of an older pre-usbnet USB to Ethernet driver. The most recent copyright date for it in the header is 2006. I can see why Raspbian wouldn’t want to merge the patch as it is never going to be in upstream Linux.

randytsuch Posted January 2, 2020 Share Posted January 2, 2020 I loaded the new (really old) version kernel again last night, and verified it pops in my system. Then tried something else. Confirmed that kernel 6 was the best one, it has the least number and lowest volume pops. Started trying the Profile Select options. I think 1 was fine, but did most of listening at Kernel 6, "Profile Select" = 2 With this selected, no pops. I guess the combination I have is rare, usbridge sig connected to a diyinhk usb to i2s card and that's why my system acts differently here. I may try the other kernels, and then try different profiles with them, but I also may just listen to music for a while lol FYI, to get allo/dietpi to work with no pops, here is what I did https://www.diyaudio.com/forums/vendor-s-bazaar/337859-shanti-dual-lps-5v-3a-5v-1-5a-92.html#post5963277 Randy My system Link to comment

Thanks Matt @matthiasI have not done a good comparison but here is the result I have so far: With Audirvana to MoOde in UPnP vs Roon in Squeezelite I have a very hard time telling the difference. I have not tried Audirvana in UPnP. I am in the process of trying to setup the same test in Gentoo Player. I also ran A/B on MoOde between Roon Endpoint and Squeezelite. And Squeezelite was better. I also need to test this with Gentoo Player. WHEW. I would have never tried Gentoo Player if I was not having trouble with MoOde and the developer was not listening. I got prodded to give it a try and I am very happy I did. Bob matthias 1 My Audio Systems Link to comment
the_bat Posted January 2, 2020 Share Posted January 2, 2020 Just a couple of things a I seem to be following Bob along the same path. I'm using the 64 bit, 4.19.71-GentooPlayer-RT-MIN-NOGRAPH-EUP100RCU-rt24+ kernel version. 1. Using Roon into Squeezelite I don't get any of the skips and glitches and track skips I was getting with other players. 2. I'm playing through the Allo USBridge Signature and DigiOne Signature spdif output and don't get any of the pops that people using the USB output seem to suffer. Oh, and the sound is very good indeed. I'm too am very happy. Alan Link to comment

I got irregular faint clicks that were audible only during quiet passages. I did wonder if I would have noticed if I wasn’t blessed (cursed?) by such a quiet listening environment.
