  2. Hello, Can the USBridge Signature be powered directly off the GPIO pins ??
  3. Hi, I just tested with my Sparky USBridge with volumio 2.657 and Windows 10 foobar2000 USB output to Meitner MA-1. It works on Sparky USB and Windows 10, both detect the MA-1 as XMOS USB audio 2.0, but connect to USBridge USB it fails with error "failed to open ALSA device "hw:1.0": no such file or directory". Please can help to resolve this issue? Thanks. Mat
  4. Wireless success: Although multiple restarts of the wireless networking failed to configure the DHCP lease, when I rebooted the USBridge Sig, I got a fully configured wireless connection, but DNS was still trying to connect through the Ethernet, even when I disconnected it. A second reboot with the Ethernet disconnected got me full Internet service, including DNS, through the wireless.
  5. Thanks. With that advice, I got the dongle recognized and configureed as wlan0. I found my two local wireless networks on a scan in dietpi-config. So far, I can't get them to configure their IP addresses, but I expect to solve that. I will post my final result here in case someone else has similar issues.
  6. There seems to be a problem with Chord Mojo and Hugo with USBridge Sig (and RPI3) due to the latest kernel move (4.19) We are investigating and hopefully we can have a solution rather fast In any case the 4.19 kernel seems to be rather unstable on USB audio . We will post news asap. https://github.com/raspberrypi/linux/issues/3204
  7. Hi, I have just get a Meitner MA-1, and I am interested to match it with Usbridge Signature (runs Volumio) as transport. Please may I know if this DAC is supported? Appreciated if someone can share experience on such combo. Thanks, Mat
  8. on RPI RTL8xxxu driver available , but its blacklisted by default in dietpi. comment the line on /etc/modprobe.d/blacklist-rtl8xxxu.conf #blacklist rtl8xxxu
  9. My advice would be to change to Moode Audio. Moode has the driver for Comfast 802.11AC WiFi dongle for USBridge Sig. Matt
  10. I found plausible settings for CONFIG_PLATFORM_ARM_RPI, except for the KSRC variable. It appears that the Makefile for the RealTek driver changes directory to a kernel source directory and runs another Makefile there. modules: $(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KSRC) M=$(shell pwd) modules /lib/modules/<version>/build is a common choice for KSRC, but there are others, such as /usr/src/<version>. The DietPi installation does not appear to have any appropriate directory with a Makefile for kernel modules. Perhaps there is a very different way to approach this problem, and perhaps I need a different WiFi dongle?
  11. Can you point to instructions for finding and installing the driver? On my Lenovo laptop running Ubuntu, the relevant drivers appear to come from a linux-modules-extra-* package with lots of irrelevant ones. None of them is called 8192eu, but my system recognizes the rtl8192eu dongle, so perhaps it is a more generic driver?
  12. In order to compile the driver for the RPI 3 computer module, it seems that I should fix the Makefile to show: CONFIG_PLATFORM_ARM_RPI = y (all other CONFIG_PLATFORM* variables set to n) and there should be a section starting with: ifeq ($(CONFIG_PLATFORM_ARM_RPI), y) I have no idea what should go in the conditional section for ARM_RPI.
  13. I just noticed that the installed modules are all of the form "rtl8192cu" while my dongle appears to be "RTL8192EU" ("CU" vs. "EU"). Not clear how to take care of that. Maybe the download allows me to compile the driver for the *EU version, if I can figure out how.
  14. I just attached the WiFi dongle (https://www.allo.com/sparky/usb-wifi-dongle.html) to my USBridge Signature (eMMC memory) in its new case. I enabled WiFi with dietpi-config. dietpi-config does not see the dongle, and reports: WiFi : Not Found | [On] | Disconnected lsusb finds the dongle: Bus 001 Device 003: ID 0bda:818b Realtek Semiconductor Corp. RTL8192EU 802.11b/g/n WLAN Adapter There are modules that appear to be appropriate: /lib/modules/4.19.73+/kernel/drivers/net/wireless/realtek/rtl8192cu/8192cu.ko /lib/modules/4.19.73-v7+/kernel/drivers/net/wireless/realtek/rtl8192cu/8192cu.ko /lib/modules/4.19.73-v7l+/kernel/drivers/net/wireless/realtek/rtl8192cu/8192cu.ko The download from the Allo product page provides an "install.sh" which claims to be for PC-Linux, and which fails when I run it. Instructions would be real helpful.
  15. IMO, the best is to go via his direct email. ATB Matt
  16. Thanks for your help. I'm afraid, the github link is gobbledegook for my limited raspi knowledge. I shall contact Tim Curtis. Maybe he is patient enough to help me.
  17. The set-up guide is here: https://github.com/moode-player/moode/blob/master/www/setup.txt Otherwise you can contact Tim Curtis here: https://www.diyaudio.com/forums/pc-based/271811-moode-audio-player-raspberry-pi-1496.html?s=114876cea8c0efe880df97e572b57b6b or via his direct email: tim at moodeaudio dot org Matt
  18. Tried moOde, flashed it onto an SSD, inserted it into the USBridge Sig, but couldn't get it to work at all. Is there some walk-through how to do it? Thanks
  19. Squeezelite renderer is integrated in Moode, so you can use Moode for Roon via Squeezelite and for Audirvana via UPnP. Matt
  20. If I understand correctly, setting 'Enable Squeezebox' in Roon requires a Squeezebox music player, correct? I don't have one, so I can't try.
  21. I could never give up Roon (because of the interface), but I prefer the way it sounds when outputting to Squeezelite. To enable this, go to Roon Settings, Setup, Enable Squeezebox Support = Yes. In Device Setup (under Advanced), I also set Use Flac Compression to No. Many of the audio OSs have Squeezelite built in.
  22. Yes, you are right, of course. The differences could be due to different transport protocols (UPnP vs RAAT). I'll try Moode and see how it goes with Audirvana. Thanks for the tip! However, based on Roon's vastly better GUI, I might be sticking to Roon for the time being. But it's always fun to optimise things. While I'm typing, I am downloading Moode. Till soon and thanks!
  23. Yes, I am sure the differences are small, so it is a matter of fine-tuning or matching. Audirvana uses UPnP. Searching different forums I found Audirvana and Moode to be a good match. Thank you for trying it and sharing your impressions. Matt
  24. I have a Isolator, Katana stack and think the OpAmp has failed (again). I have mailed Rudy, Sudeep and the gang with no response. Can you help ? I have a mail with symptoms, voltage readings and stuff which I can send (if you tell me where I should send to)
  25. The difference between Audirvana and Roon isn‘t large. I perceived Roon to be a tad more pleasant. If Audirvana had a tiny bit of edginess, Roon lacked it entirely. As in both sessions, Ropieee XL was used, the, admittedly small, difference I heard must reside in the different algorithms. Roon uses RAAT as the streaming protocol, while Audirvana uses a different one. I‘m almost convinced that a different OS like Moode, etc. will produce a slightly different SQ. I‘ll try this suggestion out in the next weeks and report back.
