    have any of the beta testers run HQplayer embedded on the Mercury? Since it's Compute4, I assume it will run similarly to a Pi4 based box, but just wanted to confirm.

    Thanks

    With ssh (cli) try doing:

    mount

    And see if the ssd shows up. If it has music files on it and is a supported file system it should either just work or we should be able to get it to work.

    I have been using I2S and AES/EBU from the beta unit into Rockna Wavelight, and these are identical volume level through the DAC outputs.

    How is the text applied? some sort of paint, etching, etc? (just curious for the diy'er that lives in some of us)

    I have created partition and mounted it manually via ssh/cli but not in Volumio. When it is done i.e. piCorePlayer allows to mount it via web interface.
    Thanks for the link, I will try to do in Volumio following the instructions.

    It worked for me, the SSD disk is now visible in Volumio, I am able to play music files from it. You also need to add an entry to /etc/fstab to be mounted automatically at boot. Please note it is assumed you already created partition on your internal SSD drive. If not then additional steps need to be performed.
    Below are the steps I did, maybe they will be useful for someone:
    1. Enable ssh in Volumio: go to http://volumio.local/dev/ -> SSH Enable (by default it is disabled and there is no option to enable it in the Volumio webgui settings)
    2. Login to ssh (I am using puTTY), user: volumio, password: volumio
    3. Identify partition of the SSD drive you want to mount: command 'lsblk'. Mine is nvme0n1p1
    4. Make a directory for the mount point, i.e. command 'mkdir /mnt/Samsung'
    5. Mount the SSD drive, i.e. command 'mount /dev/nvme0n1p1 /mnt/Samsung'
    6. Make a link, i.e.: 'sudo ln -s /mnt/Samsung /var/lib/mpd/music/Samsung' (I needed to execute as sudo here, because otherwise it didn't allow to make changes in /var/...)
    7. Update the database, command ‘mpc update’
    8. Update /etc/fstab file to mount drive automatically at boot, command 'sudo nano /etc/fstab' (type volumio for [sudo] password)
    9. I have added the following row to the file: /dev/nvme0n1p1 /mnt/Samsung ext4 auto,user,rw 0 0

    Good to see that it worked for you, too:). As you also mentioned, it's required to edit /etc/fstab and do the right settings whenever you want to auto-mount a drive, remote folder(NAS share) etc. I have been using Gentooplayer for about 3 weeks and mounted my NAS folders(total size about 2TB) and a playlist folder for LMS and make them mounted automatically at startup by adding entries to /etc/fstab.

    Before we start offering the SSD we'd need to know we can do all this and supply the SD Card with the modified image. I worry that with Volumio an update could wipe it all out. We saw this with the USB Host enable for the CM4, but Volumio provided a separate cfg.txt file that survives updates.

    Not sure what update was just applied today via Volumio, but it did not break my /etc/fstab settings - similar to what folks did above except I mounted over the standard "Internal Storage". I'm not that good at reading instructions, and did not notice until today that other folks were doing a similar setup.

    Anyways, SSD mount worked before and after the Volumio update :)

    Hi everyone,

    I have been lurking for a while and have finally registered. I have pre-ordered one of the early Mercury units. (Sorry Michael, I forgot to mention my username when ordering.

    So far I am thinking that ropieee XL might be good option to run on the Mercury. Would I be right in thinking this would allow me to use Tidal Connect and QoBuzz?

    Thanks for any help!

    If you want to use Tidal Connect, I don’t believe RopieeeXL will work for you. You can use Tidal and Qobuz via DLNA/uPnP to RopieeeXL via apps like mConnect or Bubble uPnP. Or you can use Roon and integrate those services to your Roon account.

    Tidal Connect works with RopieeeXL. But it's not supported by default. You need to install it manually by using some commandline instructions (ssh to device using Putty). I installed and played via Tidal Connect succesfully.

    I had sent a message that explains how to do it >>> Tidal Connect on RopieeeXL

    Another longtime lurker here… just placed an order. Excited to give the Mercury a whirl!!! Only real question is about the power supply (linear)… have an Uptone Lps 1.2 that can do 12 volts. Has anyone tried it with Mercury? If it doesn’t work I’d be happy to add that power supply you made to the order, once that becomes an option (didn’t see it listed on your store yet).

    Is it possible to pre-order the Mercury SBAF edition and 12V "Noise Nuke" LPS and have them shipped at the same time?

    Also, is the SBAF unit and LPS perhaps Made in US, as discussed previously in the thread? :)

    I am experimenting further with the software and mounting of the internal SSD of Mercury. This time I was able add internal SSD drive to the library of moode. It is good because moode is the software I like most. BTW, it allows to select Denafrips Pontus II R2R DAC (I2S) driver and when using this driver it outputs up to 384 kHz stream (not limited to 192 kHz as it is when using Hifiberry Digi+ Pro driver). Below are the steps I performed.
    1. Logon to moode via ssh, user: pi, password: moodeaudio
    2. Mount the SSD drive to the existing mount point in moode SDCARD, i.e.: 'sudo mount /dev/nvme0n1p1 /mnt/SDCARD' (nvme0n1p1 is the partition of my internal SSD drive, you can find it by 'lsblk -f')
    3. Add row /dev/nvme0n1p1 /mnt/SDCARD ext4 auto,user,rw 0 0 to the /etc/fstab for automounting at boot (command: 'sudo nano /etc/fstab')
    4. In webgui of moode go to Configure -> Library -> Create Music Source. Select: Type: SMB (Samba), EDIT Path manually: ip_address_of_your_Mercury/SDCard, User ID: pi, Password: moodeaudio, Name: SamsungSSD (create your own name). Note none of these fields can be left blank. Click SAVE.
    5. Click Music Database -> Regenerate Music Library

    Uptone only has 1.1A and it may be limited in current supply. It may work but not recommended

    A Meanwell GST40A12-P1J is included with Mercury. Same type as was optional for PI2AES.

    Due to regulatory testing requirements, the LPS may not be ready when we start shipping Mercury. As for country of assembly, the first batch of Mercury is being assembled in China. However, after that we plan to assemble them in the US. This is about control and managing logistics, not quality.
