Re: Ultralite AVB

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.

Re: Ultralite AVB

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.

Re: Ultralite AVB

Second and third time without hardlock. My Motu isn't plugged in right now, i'll send you the output of lsusb -v later, than...

Re: Ultralite AVB

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...

Re: Ultralite AVB

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.

Re: Ultralite AVB

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

Re: Ultralite AVB

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...
