  1. Thank you! I'll check mine.
  2. Thanks for sharing this. Mine definitely has the ELNA caps but not sure about the earth ground connection. Can you share a photo of what I should be looking for? Thanks!
  3. I swapped out the charging PSU to the LPS-1 with an Uptone branded SMPS. Previously I was using an El Cheapo LPSU. I will see if that was the issue. Thanks the suggestion.
  4. Hi John - It just happened again and the LED on the LPS-1 goes red, then amber then green. But when it went red, all of the lights on the ultraRendu went out. Gary
  5. I'm experiencing a problem that I've isolated to my ultraRendu and I'm hoping someone can offer some advice or suggestion on the easiest way to troubleshoot this. I am using an Intel NUC as a Roon server and ultraRendu as the endpoint. The ultraRendu is powered by an Uptone Audio LPS 1. I am losing signal to my DAC intermittently. The signal drops for about a minute then comes back. When the signal drops, I can still ping the NUC but I cannot ping the ultraRendu. So that leads me to believe the issue is either with the ultraRendu or the LPS 1 PSU.... or perhaps something else I'm not considering? Anyone have any advice on the easiest way to troubleshoot this? Is there a way to look at error logs in the ultraRendu that might indicate what is happening? Or is there something else that might give me some insight into what's going on? I plan to swap out the LPS 1 with another PSU for testing to narrow down the problem even further. Any ideas or suggestions would be greatly appreciated. Gary
  6. Hope you are enjoying your vacation! I've been gone the past few days myself so I haven't had a chance to do anything with it, other than install the Optane stick into the NUC. If anyone else can offer any help, I'd really appreciate it. By the way, I'm going to use the whole 32GB for Roon, so I will not need a separate partition for Roon and AL (unless there's some reason I will need to have it formatted that way). Thanks! Gary
  7. @lmitche I'm working on setting up my Optane memory to hold my Roon DB. Do I need to first 'make filesystem' on the Optane drive (ie mkfs -t ext4 /dev/nvme0n1)?
  8. I just booted into BIOS with the working usb stick and I see under Boot Order UEFI the Boot Drive shows USB: SanDisk. When I restart with the original usb stick (the one containing my Roon DB) in BIOS it does not show the USB stick. Something is amiss with it. I think the only solution is to start over, then copy over my roon files to the new stick as suggested by @LTG2010 and @austinpop
  9. Yes I agree, that is excellent advice. Thanks @LTG2010 for the simplest solution.
  10. Maybe I'm running fsck wrong. The original (main) stick is /dev/sdb and there are /dev/sdb1 and /dev/sdb2 I am running fsck /dev/sdb2 Here's a screenshot:
  11. I ran fsck on the main stick and it gave me a message saying 'clean' so I tried booting from it again and I still get the same error. Odd because one usb stick works and the other doesn't, yet they are both recognized when running fdisk -l
  12. That's a good idea! (typical response from a Linux novice like me) 😀
  13. I think I will continue to boot from a usb stick but have my roon db stored on the Optane stick. So it will probably boot to ram from the usb stick, then have some script that saves my roon db to the Optane stick. I'm not entirely sure it this is correct, but once I figure it out, I'll document it for sure.
  14. I did a ramsave because I made some changes to my Roon library (tags, added tracks to a few playlists, etc). I only made standard changes to AL: set the date & time, modified fstab to mount my external HDD that stores my Roon music library, changed from DHCP to a static IP address. That's all I can think of.
  15. Maybe bad blocks. I hope I don't have to start over because my Roon DB is on that and I have a lot of playlists, tags, etc that I don't want to have to recreate. I installed a second usb stick and booted from it and ran fdisk -l and both USB sticks are visible. But my main stick will not boot. So it may very well be corrupted. I am going to see if I can access my Roon DB files and copy them over to the working usb stick. Then install an Optane stick and copy the Roon files there so I can minimize the risk of losing all of my Roon stuff going forward.
