USBridge ID properly detected , but the DAC ID not detected on lsusb results.
did you tried with other USB ports ?
I have. It actually looks like this might be a problem with my DAC, as it usb not detected by either my PC or my Mac.
Anyone using a USBridge with a McIntosh C52 or similar? I have an issue where the first few notes of tracks are muted. I can see the display on the C52 show āSilentā on the USB input in between tracks which signifies no signal and is the same message I get when nothing is being played. Iāve messed with the track delay in Roon but it makes no difference. I asked on the McIntosh forums and folks are using Sonore & Auralic streamers with no issue so Iām wondering what the USBridge is doing differently. I contacted McIntosh support and they just told me to connect a laptop directly to the USB input and that JRiver doesnāt have this issue!
I have a MA9000 which have the identical DAC module. But I donāt have Allo USBridge anymore, so I canāt test it. I had similar issues at times with other devices till I changed the settings in āUSB Automuteā in my amplifier to āOffā
Sounds perfect except that option isnāt exposed on the C52
EDIT : I just saw the thread in support showing other folks have the issue with Dietpiā¦
Anyone else having an issue updating to Version 1.0 (Build 167)? Roon says the update is downloading & installing but then states āThere was an error checking for an updateā.
Iāve tried uninstalling the Roon client in dietpi and reinstalled but still it shows the previous version of 164 and then attempts the same cycle as above.
Just performed this, without any issueā¦
(On my USBridge with DietPi, clean install)
This was not true, sorry bout the confusion. The install seemed to do fine, but the version number never changed. I too have manually installed.
All my ropieee bridge installs updated to 167 no issue, but all my dietpi sparky x2 and a rpi are stuck at 164 still
I have this exact same thing @Mike_Ormerod and @wizardofoz , did either of you find a way to solve it?
I manually updated.
Thanks, I did too in the end.
please could you describe me exactly how to use Qobuz and Spotify with the USBridge ?
thanks.
Hi @erho no problem. You need need to be ok with Linux and ssh to do it. First you need Diet pi installed as the operating system, this came as standard. You need to ssh into the device and then from dietpi-software menu install Raspotify and you also need MPD Music Player Daemon.
Raspotify is for Spotify connectā¦You need to change a few things in Raspotify settings file to get the high quality stream and thatās about it. You need to look up itās location in Dietpi.cant remmebr off hand as I donāt use the bridge anymore. Main instructions here about it you can ignore the install as dietpi does it for you. https://github.com/dtcooper/raspotify/blob/master/README.md
MPD is a player software that will help you play Qobuz but you also need to install a upnp client called upmpdcli which works with it.
https://www.lesbonscomptes.com/upmpdcli/downloads.html.
You dont need to change much here if you donāt want to and you can ignore the bits about Qobuz and Tidal as you dont need them as you can use a phone app for that bit.
Get either Kazoo or Lumin app for your Phone, these will see the upmpdcli as upnp renderer to play to and they have accees to Qobuz in then you just need to add your credentials.
One question, over night is it recommended to shut down the device or to leave it on permanently?
Hi Eric,
I definitely would leave it on all of the time. Power draw is minute (on the order of 1.7 watts), and digital gear tends to work best when left on for 24-48 hours at least anyway.
Pro tipā¦Iāve found that the USBridge sounds a bit nicer when an iFi Audio DC iPurifier2 is connected in-line with the provided 5V power supply. Iāve tried separately powering the Sparky board using a high quality 5V DC source; however, Iām not sure that this improved the sound further.
Glad that I found this board thoughā¦I have been using the USBridge (DietPi + Roon Bridge) for nearly a year but do have a question. Iāve observed that when I have one of my iFi Audio DACs directly connected to my Apple MacBook Pro and stream MQA, the Signal Path shows more complete information, including the āMQA Renderer ORSFā sampling rate and āAnalog Outputā stages. This information is absent from Signal Path when streaming to an iFi DAC that is connected to the Allo USBridge. Hereās a simple example:
āLoft Sparkyā, of course, is the name of my USBridge. Although Signal Path shows that the iFi USB Driver is recognized, the ORFS Renderer information is missing on the USBridge. Before you ask, I verified that the settings were identical for both zones: āMQA Capabilitiesā set to āRenderer Onlyā and āEnable MQA Core Decoderā set to āYesā for both. In this instance, DSP and volume leveling are disabled for simplicity:
The options are a little different for MacOS vs. Linux/DietPi, but as you can see, they are essentially identical, yet the signal path (above) is not. What is especially curious is that the Signal Path on the MacBook Pro is flagged as āEnhancedā while itās āLosslessā on the Allo USBridge. I assume this is because Roon is not trying to guess what happens after the signal is received by the ALSA driver? Not sure. Itās also strange that Roon Core has to work a bit harder in the MacBook Pro case than for the USBridge (note the āProcessing speed: 18.2xā for the Mac case yet absent for the USBridge case).
Hereās another example with my more typical settingsā¦DSP and volume leveling enabled and identical between MacBook Pro and USBridge. In this case, Signal Path is āEnhancedā for both, as youād expect:
Iām not really worried about thisā¦as far as I can tell, the iFi DAC is rendering the MQA stream the same way in both cases. It would be nice; however, if iFi and Roon would work together to properly add the iFi DACs to Roonās database so that the graphics show up and the signal path is complete for iFI DACs that are connected via the Allo USBridge.
BTW, I have tried manually identifying the device as Allo USBridge (does result in the correct graphic for the Allo) and then manually overriding all of the settings so that they match what Iāve shown above. No change in the signal path thoughā¦MQA Renderer ORFS and analog output are still missing. Iām interested in hearing from others who may have similar configurations, and especially from Roon and iFi about possibly adding these DACs as first-class citizens. Iām happy to help with testing!
Rebooted my USBridge this morning and now no matter what I do Roon doesnāt see the USB output
Check it shows up in the os it might have died or lost it as the main audio device in deitpi. Mine started to do this and that it died permanently.
Ssh in and go for dietpi-config and choose usb-dac and reboot via the shell.
