Jambox in a Jacktrip Virtual Studio box (pi4+Hifiberry Dac adc pro hat) #80

I've used exactly the hardware you describe with the jambox 1.3beta3 image,
burned with the Raspberry Pi Imager on a mac, and copied directly with dd.
Nothing in your message suggests a problem with your methodology, but I can
confirm that the software should work fine if the VS software works.
https://github.com/kdoren/jambox-pi-gen/releases/tag/v1.3.0b3
Perhaps try the RP Imager, (no need to unzip the image) or if you're
already doing so, then you might provide a bit more detail so we can
consider how to help.
Good luck,
Carlos

I have tried to have Jambox in a Virtual Studio Jacktrip pre-built box.
The box consists of a pi4 2GB, and a Hifiberry DAC+AdC pro hat.
The card flashes twice until reaching a rainbow screen twice and then
stays in rainbow for all versions of Jambox 1.3.
Is there something I should do or anywhere I can look for help? Any Sha to
check the files are downloaded correctly. I downloaded them twice with the
same results.
I have tried with a couple of cards. The included Jacktrip card works fine.

Glad to hear that you're making progress. I don't honestly know if the
hifiberry stores config across poweroff, nor am I well-versed in the many
options presented in the pimixer features. But I would expect that it
would "just work" out of the box. I generally run headless, so I have
never really played much with video on the RPi 4, but I do recall having
similar trouble with the second hdmi interface, and there were some times
when I couldn't get video out of the first interface either; I don't recall
ever figuring out why.
Sorry I don't have more info for you, but it certainly sounds like you're
close now!

Update: I put back the [pi400] to its original, and waited the boot time.
I then put the hdmi cable and saw nothing.
I then put the hdmi cable *in the first connector*, and could see the
image. I have subsequently put the monitor in the first plug, and has been
rebooting without problem.
I wonder if this has to do with the "2 monitor post below":

I wonder still about your configuration for the hifiberry DAC+ADC pro.
All I need now is to set up the hifiberry DAC+ADC pro.

@adrian-u-soto @CAguayo That's strange, I run jambox on RPi 1.2 with a hifiberry with no problems. If you are connecting a single monitor, you should plug it into the HDMI connector next to the USB-C connector. Was the problem only when the HDMI monitor was connected? Pi400 is known to fail to boot unless the vc4-fkms-v3d overlay driver is loaded, not sure why. That's the reason i put the [pi400] section at the bottom of /boot/config.txt. pi400 is supposed to be just a Pi4 in a keyboard case, yet it behaved differently. I wonder if that difference has now made it into pi4 shipments. Did you buy yours recently? The vc4-fkms-v3d driver enables the use of dual monitors, and also dynamic display resolution changes. However I've kept it disabled on Pi4 for 2 reasons. (1) it introduces a small amount of additional overhead, and (2) I believe it has a bug which causes the display to lock up occasionally. I have seen such lockups (days apart) on some Pi4s with that driver, and they are all rock-solid when it's disabled. You could try booting to the standard (non PREEMPT_RT) kernel by temporarily changing [pi4] to [none] in the kernel section (5.10.25-rt35-v7l+) near the bottom of /boot/config.txt, to see if that makes any difference. What are the outputs from the following?
