Just to repeat, that means a device can work properly in Jack even if it doesn't in Alsa / PulseAudio. This is an important info for me, thanks.

Also, thanks for another info, if I don't manage to solve this problem, Behringer 404HD might be a good alternative.

Code: Select all

jackd -d alsa --device hw:2

Then start QJackctl and look for IN and OUT-puts of your card.


I tried the command you specified and variations: 2,0, S1810c, S1810c,0, -P instead of --device, specified the number of out channels with -o, in all these cases jack fails. For example:

Code: Select all

jackd -d alsa --device hw:2

Increasing verbocity didn't provide more info, ALSA lines were the same.

That Jack does not want to start w/ this device is worrisome. :?:

From some other command line output that you posted it seemed to me that the (standard?) USB audio device driver from Alsa was loaded. It almost looks like the Presonos Studio 1810 is not supported by this driver. Almost every cheap USB sound "stick" up to my Behringer 404HD works with the driver called snd_usb_audio.

Check if the kernel module (read: driver) named snd_usb_audio is loaded:

Code: Select all

$ lsmod | grep usb

snd_usbmidi_lib        29282  1 snd_usb_audio

Wat seems very strange to me is that they say that the device works in MacOS because it's class compliant. The Presonus Studio1810c looks like a very nice audio card to me. Pity that it doesn't seem to work in Linux. I couldn't find anything on the internet about this device and Linux, other than that Linuxers ask for a port to Linux of Presonos' software. Is it a very new device?

If it is really class compliant then the developers at Alsa might pick up on it and find a way to support it. The tip you got from somebody to contact ALsa might be your best option at the moment...

Both snd_usb_audio and snd_usbmidi_lib modules are loaded upon connecting S1810c. I can check module parameters in /sys/module/ ..., I also changed index parameter by editing /etc/modprobe.d/alsa-base.conf and it worked as expected.

I just checked it on a Mac. Disconnected network to make sure nothing is downloaded and connected the device, for the first time on this computer. The device showed up in System preferences but I couldn't use it from there because it said "The selected device has no input / output controls", probably to be expected. Opened (pre-installed) Audacity, both play and record worked immediately. That's even without the software that Presonus recommends (was not installed). So it looks like it is class compliant.

Thanks for the tip, I agree, hopefully I have enough info by now to convince ALSA devs to look at this
