I got the source from kernel.org and all I did was replacing sound/usb/misc/ua101.c completely.
I didn't apply any patches.
Well I figured out the patch system and now I'm on a patched 5.8.6 and all seems well so far (about 30 mins) so congrats and thank you to you and drumfix for a working patch!

Some gotchas in my case (MOTU 1248):

  • Asmedia 3.1 port didn't work, Intel 3.0 port does
  • Must boot with it connected and turned on
  • Set midi property in motuavb.conf to false
  • Set number of I/O channels in Routing page to 8x8
  • This is just a plain Manjaro KDE install other than patch, haven't tried JACK yet

I really just installed Manjaro in the hopes that 5.8 would work OTB and have ended up here. So next up for me is to install JACK, etc. and see how that all goes. I might even just re-install Ubuntu Studio and try patching that instead.

I am surprised that other interfaces than the UltraLite AVB work at all. That's cool.

You can force loading of the driver on boot by putting a line into the file /etc/modules (including the module parameters).
See "man modules".

You can check what driver the device is using by "lsusb -t"
Important is to look at inderfaces 0,1,2.
If they are using snd-usb-audio then just execute the following commands:

sudo rmmod snd_ua101
sudo rmmod snd_usb-audio
sudo modprobe snd_ua101 <your module parameters>
sudo modprobe snd-usb-audio

Hello Drumfix and Bluebell,
You can force loading of the driver on boot
That is what I wanted to "test further". It solves my issue. In /etc/modules-load.d/motu.conf :

Code: Select all

snd_ua101
And in my /etc/modprobe.d/alsa.conf the options to fit my setup :

Code: Select all

options snd_ua101 samplerate=48000 midi=1 index=1
No samplerate changes !! It went from "kinda working" to "just working". I want to thank Drumfix and Bluebell for their work and help. The 828 is now a killer soundcard for my use.

What interface exactly? UltraLite AVB? The old one or the new one with ESS chips?

Hello,

i have the same issues as root2 with the new driver. I have also the Ultralite AVB ESS with Firmware 1.3.5+637. In the moment i'm testing with kernel 5.8.8.
If I use the device only with Pulseaudio, i have sometimes distortions and sound disappears. If using with jackd sound disappears immediately
sometimes after 10-20 minutes, sometimes after hours of use. Restarting jackd helps.

Is the correct driver loaded?
