I’m not sure why I can’t see or hear my spanking brand-new Schiit Modi 3E. Is it because I’m using the 5.17.74 Kernel? I tried 6.02 but that sent my computing into a frenzy. Maybe 6.01 would work better and ultimately see it?
Thanks, I was going to contact them as a last resource. Yes, the switch is all the way up selected for USB. I was thinking maybe it’s pipewire, maybe have to deal with QtJack, dunno. I was wondering if there is a switch to have the computer pump audio through USB, but I haven’t found that. And I’m not an expert either :\

Yeah, if it’s not actually ‘seeing’ the device at the kernel level, then the other stuff involving Pipewire, etc is not really relevant.
Hope you manage to get some joy from Schitt support. IMHO, USB Audio compliant devices are normally pretty easy to use with Linux and need little in the way of setup. My ifi Dac just worked straight away.
Yup, that’s why I got that one. It was $125 and fairly affordable. The fact my Apple laptop doesn’t recognize it either could mean it has a problem.
Thanks for your feedback. I tried using kernel 6.02 but it didn’t recognize a lot of things on my computer. Maybe 6.01 will. I will try next. I did contact Schiit. Damn, I’m bumbed…
According to the specs, the Chipset used for the USB interface is C-Media CM6631A. Looking at linux-hardware, it should at least be detected with lsusb .

Yup, I started a troubleshooting ticket with them. Will update this thread as needed unless it should be closed?
They just answered my ticket. They’re talking about disabling port power management. I’ve read up on this elsewhere. I need to find how to do it here. I didn’t have the right folder although I was reading an Arch Linux site.
The USB specification states that all USB devices must support power management. Nevertheless, the sad fact is that many devices do not support it very well. You can suspend them all right, but when you try to resume them they disconnect themselves from the USB bus or they stop working entirely. This seems to be especially prevalent among printers and scanners, but plenty of other types of device have the same deficiency.
For this reason, by default the kernel disables autosuspend (the power/control attribute is initialized to on) for all devices other than hubs. Hubs, at least, appear to be reasonably well-behaved in this regard.
It does talk about low powered USB and adding the DAC to my USB hub. It’s strange because they ship the DAC with a USB power outlet.
" 1. If you’re using a computer source, make sure you’ve selected SPDIF output in BOTH System Preferences/Control Panel and your non-iTunes player software (Bitperfect, Amarra, Audirvana, Foobar, JRiver, etc…) Sometimes you’ll have to restart the player again, too."
I’m still not finding all the tweaks in the GUI control panel.
I did nothing a slight sound on my stereo when I plugged in the USB of the DAC, so something is coming through.
OK, So I’m going to connect an older USB hub I have. Drats, now that I think about it, these USB hubs are a decade old. I wonder if they’re still USB A. Maybe I should spring for a new USB hub.
I must say I’ve personally not encountered this low-power thing being an issue with Dacs, at least not on Linux. (Also, it doesn’t help that the link Schitt provides for Mac info now redirects to a different page…)
Sadly I’m afraid that’s about the limit of my knowledge regarding USB power. Hopefully someone else on here might have some other suggestions. I thought the whole point of USB was to make stuff like this easier!
@33Nicolas
I think they did point you in the right direction regarding the USB power. You may want to try disabling usb autosuspend. Other options are try different usb ports, shorter different cables. Better powered usb hub?
I’m going to try this today. I’ll plug it into the hub directly. I meant that my USB hub is easily a decade old and maybe this device needs some of the faster more modern USB connection, but now that I’ve said this, electricity should be the same.
