I was wrong about the distortion, sorry about that. My Server rebooted and i didn't realize it booted back to the unpatched realtime kernel. If i play via alsa on channel 16 it hops to 24.

I left my Motu powered overnight and it switched channels again
Anyway, no distortion in 12h runtime is very promising! Thanks @Drumfix

Edit: After some days of usage i got multiple Distortions. Sometimes it recovers automatically after 1-3 minutes.

I forgot to mention that even with your kernel patch applied i got channel hopping modulo 8 :( Here's the output of lsusb -v: Bus 001 Device 006: ID 07fd:0005 Mark of the Unicorn UltraLite AVB Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 239 Miscellaneous Device bDeviceSu...

That sound's great. I really wanna keep my Ultralite! I also experienced the "scheduling while atomic" bug without hardlock. First time stopping/starting playback -> hardlock. Second and third time without hardlock. My Motu isn't plugged in right now, i'll send you the output of lsusb -v l...

I tried the new patch for 5.7.0-rc4 but i am also getting errors and freezes... Is there any hope this patch works with the ESS Version?

Thank you, i'll try your patches later Do you have them as a .patch file?
What's better, usb2 or usb3?

I was so excited about this Interface, i really hope i can get it to work. Btw, i am using this for my Home Automation. There are not many Interfaces out there with an API. I think with the current Software Version it is completly unusable if you need USB. We should spread the word! I pressed the ou...

Thanks for your answer. I already got it working again by pressing two buttons while booting (bootloader mode) and flashing the newest firmware again. It seems like i have the new Version Even with LTC i get distorted audio after one minute.

Thank you very much. Sadly my Ultralite does not boot after the Firmware Downgrade. It's stuck in load animation

I recently bought the Ultralite AVB and it came with Firmware 1.3.5+637. I also experienced channel hopping and distorted sound :( Can you send me that beta firmware too? Thank's in advice! The firmware that should work without any additional patches is this one: http://cdn-data.motu.com/downloads/a...
