Re: New Metric Halo ULN-8 mkIV
I am afraid that you cannot control the mixer with a Linux-only setup, so it's a mere „We had to make it Class Compliant because of our Macs but we don’t give a fuck about Linux.“stanlea wrote: ↑Fri Oct 29, 2021 6:44 am https://mhsecure.com/products/mkIV/ULN8mkIV.html#usb
A new "very" high end interface, they said it is Linux compatible... who's got money here ?

Re: New Metric Halo ULN-8 mkIV
Hi, I'm late but:
We have two of these in the Studio. Since its class compliant it's well recognized ootb with jack. However, after one hour of use, or a big hum appears, or a noise, and mic signal itself disappears...
no idea why.
And as say bluebell: no direct control, but I guess you can set everything easy from front panel...
I'm curious if anybody else experienced same issue?

Re: New Metric Halo ULN-8 mkIV
Actually, this happens because I use two interfaces in Jackd:
-a class-compliant USB DAC with 2 outputs
-ULN-8 for inputs
If I use only UNL-8 it works, at least longer, I only tried about two hours.
Maybe something to do with wordclock settings? (DAC has no WC, so no way to sync through hardware). I tried to "cycle" setting, I'll test longer to be sure it works. If not I'll open a new thread.

Re: New Metric Halo ULN-8 mkIV
I think what people are starting to discover is that, even when a product is advertised as "class-compliant", that doesn't mean that it isn't buggy, or implemented poorly, or has some other issue that prevents it from working on Linux.
The bottom line: Even if a product is "class-compliant", assume that it doesn't work with ALSA until/unless someone actually tests the device with Linux. There's just too much that can go wrong.

Re: New Metric Halo ULN-8 mkIV
I worked on the ULN-8 in duplex mode on a Pure Data patch, a bit unstable. On each CPU peak, something crashed and this very loud noise again. I had to "switch master" or restart jackd to get it work again.
So no, doesn't work, at least for me...

Re: New Metric Halo ULN-8 mkIV
Anecdotally, I just got back from a session where I tried to use either of a pair of these with my machine in someone else's studio. They were both picked up by pipewire & pavu but I couldn't get either of them to make a sound. It could have been a configuration issue (he had been using them over RJ45 through their proprietary link whatever thing), but we didn't push it.

Re: New Metric Halo ULN-8 mkIV
thank you for the feedback...
If you have opportunity to try with Jack it would be nice!
