    This has come up a few times. The PI2AES is based on the Cirrus/Wolfson WM8804 AES transmitter. Additionally there are two GPIO used to select the proper MCLK. This is 22.5792Mhz for 44.1Khz based files, and 24.576Mhz for 48Khz based files. Since we use the same chip and the same GPIO as the HifiBerry Digi+ Pro, that card selection can be used for the PI2AES.

    Which jumper did you remove? The one on the 16-pin header, pins 13-14 should stay. The one marked PI5V is what you want to remove.

    Did that work? Be nice to know that you’re up and running.

    As for Jriver I have no idea, I thought that was a PC only tool. Hopefully others can chime in.

    JRiver is available for Raspberry Pi. No personal experience, but it has been reported to work with Allo DigiOne and Hifiberry, so there is a good chance it would work for Pi2AES.

    Yes.
    I run MoOde and JRiver on a Pi2AES. Stock MoOde doesn't give you the desktop functionality that JRiver needs but the Pi install guides on the JRiver forum linked to above take you through this. It is a little bit fiddly and the most recent version of MoOde required a slightly different approach.

    Good to know that by being cheap, I actual chose a cleaner solution. Though I'm using the Zero W and connecting to my network with Wi-Fi, so there's that.

    I was able to put a small number of additional boards into stock today after reworking some boards that came from the factory with some minor issues. There should still be 15 or 16 in there right now, but I don’t know how long that will last obviously.

    We are working on another 100 unit lot being built domestically so it should be here by the end of the month or beginning of July. Will hold the price now based on that small increase we already had and that hopefully will cover the increase in our cost.

    Not sure if this is the best place to post this; feels like we have too many Pi2AES threads.

    I have 2 Pi2AES boxes and was running both with RoPieeeXL. Both are used as AES Airplay streaming boxes.

    I had my first running RoPieeeXL for a few weeks and had no issues. Around the time I built my second, I started having Airplay dropouts. Not sure if it was an update that caused this or what. Well the second Pi had major issues with RoPieeeXL. Frequent dropouts and the whole unit freezing after being left unused over night. I would have to unplug and replug power to get it to respond again.

    After a few days of this crap, I decided to change both over to Volumio. The loaner unit we had going around never had these issues,
    and I’m guessing it was probably shutdown improperly a lot, to no ill effect. So long story short, both Pi’s are back to normal on Volumio. No dropouts and no freezing issues.

    I just thought I’d share this experience, in case anyone else with RoPieeeXL is having similar problems. I do notice Volumio has a default system buffer of 2mb and 10% (and can be given larger buffer). Not sure what RoPieeeXL has or if you can even change it, since it’s a limited/simplified OS. Something I noticed after the fact. Hopefully Volumio stays stable for me.

    So we will not be renaming this the “super best audio friends of the PI2AES” forum? ;)

    Our next build off 100 units is fully underway. We have re-enabled ordering. Lead time is 3-4 weeks.

    One of my Pi2aes has become undiscoverable all of a sudden.

    There was some kind of incident last might maybe the internet went out for a moment which seems to really f**k with this system.

    I got logged out of Tidal and had to log back in again 3 times which is unusual. Qobuz was fine. Both Pi2aes disappeared from bubbleUPNP. I did the usual unplug both and plug back into power. Then restart my Samsung S10e and reopen bubbleupnp. This always solves it. But both Pi2aes were still gone. I had to redo that about 6 times. At one point both showed up on my iPod touch AirPlay which told me it was a bubbleupnp issue not the Pi2AES. But only my headphones Pi2aes showed up on bubbleupnp. restarting the phone did nothing. Now only the headphones Pi2aes shows up on both bubbleupnp and airplay. Cutting the power and resetting my speakers Pi2aes does nothing. Still won’t show up.

    I’m guessing I have to re flash Moode? Such a pain in the ass.

    I don’t understand how this system goes from working to not working all of a sudden without anything changing. It’s just had a winning streak too of both working for a log time.

    Was it a power outage that reset your router maybe? The pi doesn’t always handle sudden power loss gracefully as it can corrupt the microsd card it uses for booting. It’s always better to try to ssh in and use “sudo shutdown now” rather than just yanking the plug. If the microsd card has been corrupted there’s not much that can be done about having to reflash unfortunately.

    There was a distro that claimed to be mostly memory resident that might help if you have frequent power outages and there was a patch someone posted for moode that moved the logs to a ram drive but I don’t remember much about that other than looking to see if it worked (it did).

    To be sure your Pis are not working, I’d recommend using fing to look at all devices on the network. If you find them but accessing using .local doesn’t work, you can use the IP address directly in your browser. From there you can check the settings. If they don’t show up with fing and restarts then I’d try reflashing.

    Sorry I can only offer brief help, I’m traveling for a couple days.

    Agree with all the above comments. However, typical result of a power outage is my Moode startup completes before the WiFi router is available. I simply connect to the Moode hotspot and restart Moode.

    No but my headphones Pi2AES works fine and I don't think the router is the problem the internet was working while the whole incident happened (I kept checking to see if that was the problem)

    No power outage

    I checked FING and it found "Moode Headphones" as I named my headphones Pi2AES but could not find my speakers Pi2AES. I tried entering all the generic addresses and none of them worked.

    So I've just downloaded a fresh version of Moode. I formatted the card to MS-DOS (FAT) as recommended on a site online. Moode is flashed to the card in my speakers Pi2AES and it's connected to Ethernet. But it doesn't show up in FING and none of the "generic" addresses load.

    moose.local just loads my headphones Pi2AES.

    I'm at a loss as to what to do now...

    thank you for your help everyone!

    Reset the wifi router anyway. It’s got nothing to do with the internet connectivity, it has to do with the local LAN devices. Honestly it’s probably not the issue, but worth ruling out. I’ve had these types of device discovery issues before that only ever seemed to get resolved with a router reboot.
