Presonus Studio 1824c USB audio interface driver

Hello there.

I bought a PreSonus Studio 1824c USB audio interface. It works on my Mac Mini but I was wondering to use it with my Arch Linux box as well.
I'm trying to figure out if there is any driver / module for this device. At the moment, when I connect the device into my PC I get the following messages:

[31558.931924] usb 3-4: new high-speed USB device number 4 using xhci_hcd

[31560.161931] usb 3-4: 1:3: usb_set_interface failed (-32)
...

I have my Arch Linux updated, running kernel version 5.12.8-arch1-1

Any ideas?

Kind regards,
Carlos Santos

Re: Presonus Studio 1824c USB audio interface driver

I would think ALSA should be enough to power the sound card. My feeling is your issue is more related to the USB controller or the Bus but I could be wrong.
For a start, what is the output of lsusb (to check where in the bus it's located)?
Is the device plugged-in a multi-usb hub?

Hi.
The device is plugged-in on a USB port of the motherboard.
This is the output of lsusb

$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 046d:0825 Logitech, Inc. Webcam C270
Bus 003 Device 002: ID 194f:010d PreSonus Audio Electronics, Inc. Studio 1824c
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 046d:c227 Logitech, Inc. G15 Refresh Keyboard
Bus 001 Device 004: ID 046d:c539 Logitech, Inc. USB Receiver
Bus 001 Device 003: ID 046d:c226 Logitech, Inc. G15 Refresh Keyboard
Bus 001 Device 002: ID 046d:c223 Logitech, Inc. G11/G15 Keyboard / USB Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

ALSA detects the device:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: S1824c [Studio 1824c], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1

...

It seems it also finds the outputs as:

...

alsamixer says the chipset is USB Mixer but shows me no playback nor capture  controls. For playback a just see an "Internal" option with "Presonus clock selector".
Can't play nor record any sound... sad

Thanks,


Carlos Santos

Re: Presonus Studio 1824c USB audio interface driver

On further search I found this phoronix article that is very much relevant:
https://www.phoronix.com/scan.php?page= … 810c-USB-C
The article is a year old and the mentioned support might already be in the kernel and ALSA but I think it's worth a look.
