Behringer U-Phoria UM2 Does not connect

Post by Avocari »

Hi guys!
So I recently bought the Behringer U-Phoria UM2 for both headphone output and Microphone input.
On windows everything works just fine, but when I boot Linux (DualBoot) I cannot seem to find the interface (and cannot use it) and also the led indicating +48V is not lit.

I am currently using Linux Mint 19 Cinnamon (Cinnamon 3.8.9 and Kernel version 4.15.0-46-generic)

Does someone have an Idea what I can do?

Cheers,
Avocari

Run alsamixer from a terminal. Use F6 to select a sound card and see if it's displayed. If it is, select it and ensure the master output is turned up. Then, even if it's not seen in alsamixer, install pavucontrol and see if that detects it.

Failing that, ensure the device is plugged in and post the output of this terminal command:

Code: Select all

inxi -Fxz
Enclose the results between [ⅽode] and [/ⅽode] code markers by selecting </> from the mini toolbar above the textbox where you type your reply. Note that it's a capital F in that command, followed by lower case xz. You can copy the text from the terminal screen by selecting it then right-clicking.

Hi Avocari, and welcome to the forum.

You said the +48v light isn't lit. Is the Power light lit? Is the +48v switch on the back in the On position?

When I connect my UM2, this is added to my inxi output in the Audio section:

Code: Select all

           Card-4 Texas Instruments PCM2902 Audio Codec driver: USB Audio usb-ID: 003-005
           Sound: Advanced Linux Sound Architecture v: k4.15.0-45-generic
For some reason, yours isn't being detected yet. Does running lsusb in the terminal show something similar to Bus 003 Device 005: ID 08bb:2902 Texas Instruments PCM2902 Audio Codec?

I'd say, try another USB port first, and preferably USB2, not USB3. And you're not plugging into a hub are you?

Hopefully something here will get us closer to solving this.

Hi guys,
Sorry for the late reply.

running lsusb gave me this line:

Code: Select all

Bus 008 Device 003: ID 08bb:2902 Texas Instruments PCM2902 Audio Codec
So there is still hope I guess :)

All right. Let's see if the necessary modules are loaded. What's the output of running lsmod | grep usb in the terminal?

Something strange is going on. lsusb looks good, and the usb audio modules are loaded, but no sign of the device in the inxi results.

First look on the Configuration tab of pavucontrol and see if there's any USB Audio device at all. Failing that, shut down the computer for a few minutes. Then power up and see if it appears. Maybe while powering up make a quick stop in your BIOS to see if any USB settings might need changing.

If still no luck, try running sudo alsa-force-reload in the terminal, and see if that got it to show up.

Good luck.

EDIT: Are you plugged into a USB2 port?

Hi so alsa force-reload got my device showing up!
The Power LED and also the +48V is now lit!
Still I am unable to select neither my microphone nor my headphone....

Yeah. We're getting there.

You'll need to set it up properly (hopefully possible) on the Configuration tab of pavucontrol. If you paste the output of pacmd list-cards we'll be able to see all the options you have available. You'll want it set to something that has both input and output.

Re: Behringer U-Phoria UM2 Does not connect

Post by MrEen »

Very good. This should get you all fixed up:

Open pavucontrol and on the Configuration tab for the USB device set the Profile to Analog Stereo Duplex (looks like it's already set to that.)

Then go to the Input Devices tab and set the Port for the USB device to default (fallback) by clicking on the check mark next to it so it is highlighted.

Now go to the Output Devices tab and do the same for the USB device there.

I am not certain what names will show as available for the Ports on those last 2 tabs. Might be only Analog Input and Analog Output. You might need to adjust those.

Good luck.
