Hi,

I use Linux OS and I would like to know if those 2 products are compatible with Linux Ubuntu 21 e.g.:

Behringer Studio L and U-Phoria UMC404HD

I know that under Windows you need to download drivers to make them work correctly, but what about Linux ?

Thx

This did not work for me right out of the box and took me sometime to figure this out so I figured I should post my findings here in case if someone else encounters this problem.

So I have UMC1820 and ADA8200 connected with a toslink cable from UMC optical out to ADA optical in. "OPT I/O" button on UMC is pushed in for ADAT option. The UMC USB is connected to a Linux computer running Fedora 34 (the same applies for Fedora 33). My hopes are to get 18 analog outputs where Channels 1 through 10 are analog outputs on the UMC1820 itself, Channels 13-20 are sent via Optical ADAT to ADA8200 where they would be come analog outs. Channels 11 and 12 are coming out of RCA SPDIF connector and will not be used, hence I am planing on using ony 18 ouptuts from this system.

However, at first, I would get audio from UMC analog outs 1-10, and from ADA outs 5-8, while ADA uts 1-4 have nothing. 

What it turned out to be is that the first 4 channels of ADAT were "off" and I have no clue why and how. I found this out by accident when I tried to use UCM1820 in Windows PC and UCM Control Pannel software showed that in  rather obvious way. However, switching the channels on in Windows and then trying to connect the box to Linux was not sucessful. I believe the problem is that when the settings of the disbled channels were initially stred in the driver under Linux and then were pushed back to the UMC box when it is attached. Perhaps if the box frst attached to a Windows PC and adjusted, then after that attached to the Linux, then everythng would be ok, but in my case it was not.

Neither Alsa nor Pulseaudio, nor Pipewire were able to get anything going with the ADA channels 1-4 or more accurately, channels 13-16 of the UMC1820...

Alsamixer was not offering a wya to enable the disabled as everything I could find in the "alsamixer" was on.

However, usig utility "am ixer" offerd more insights.

"amixer -c 0 scontrols" returned a handful of entries one of which was "UMC1820 Output,0" and "UMC1820 Output,1"

"amixer -c 0 sget 'UMC1820 Output,0'" returned what I was needed

which was the first 3 out of 7 last lines "?: Playback 127 [100%] [0.00db] [on]" and 4 last lines  "?: Playback 127 [100%] [0.00db] [off]"

That "off" in the last 4 lines was causing me the grief. 

All I needed to do is to run

"amixer -c 0 sset 'UMC1820 Output,0' 127 on"

This command sets everything to [100%] and [on] so all outputs of the UMC1820 including all 8 ADAT channels are set to 100% and not muted.

After this I was getting output on all analog outputs that my system of UMC1820+ADAT8200 had to offer and if I play a 20-channel audio file via ALSA or PULSE I would get chanels 1-10 out of the UMC and channels 13-20 out of ADA... channels 11-12 would come out of Coax SPDIF and are basicaly to be ignored as I do not have SPDIF to ananlog converter.

Obviously Linux is not really offering much meaningful controls over the Behringer UMC1820 by itself, but setting up .asoundrc file can cure the problem.

In my case I had to add "dmix" plug that captures all 20 channels, then use "softvol" plug that would add volume control over the "dmix" device and thus be the master volume control over ll 20 channels. Then I had to add plugs to the "dmix" device for each pair of channels using "ttable" so I get 9 stereo pairs... Then I added 9 "softvol" plugs, one ofr each of the pair so each has an individual volume control. And that is basically what I needed. If anyone needs me to share exactly what I was doing in this paragraph, please put in the the replies and I will elaborate in more details. 

Hi everyone,

up until a couple days ago my setup (ADA8200<->RME Babyface / 2 cables) worked just fine, and now there is no more sound coming from the ada8200 to Totalmix / RME Babyface Pro. On the front of the ada8200 the input signal lamp is flickering according to the signal I put in, the ADA is set to Slave and the green 'locked' LED is on (which means the two devices are talking to one another?). 

The Babyface's firmware is up to date. 

Has anyone any ideas what I'm missing? Help would be super much appreciated! :)

regards, Tobias

I'm trying to use an Ultramatch Pro SRC2496 to test an AES/EBU device. I'd like to use the SRC2496's A/D converter to convert my analog to 48kHzs AES/EBU, hand it to the device under test, and then take the resulting AES/EBU and use the D/A converter to convert it back to analog.

The test isn't going well, so as a check I'm plugging a cable directly from the SRC2496's digital out back to its digital in, and then trying to run analog audio through it. No dice: the SRC2496 always behaves as if no cable is connected.

Cables:

• 2 x XLR analog source cables connected to Analog Inputs
• 2 x XLR analog destination cables connected to Analog Outputs
• XLR cable from DIGITAL INPUT XLR to DIGITAL OUTPUT XLR
• Power ;)

Settings:

• Gain knob: 0
• Mode: A/D & D/A CONV
• Sample rate: 48kHz
• Clock: Internal
• Format: AES/EBU
• Word length: 24 bit
• Dither, Emphasis and Copy: all off

With "Source" set to "Analog In", I can see the meters bouncing with my source audio, but change it to "Analog Output" and I see nothing. The "ERROR" LED is off, and the "PLL LOCK" LED is green.

All of this is the same whether or not I have the AES/EBU loopback cable connected.

Can the SRC2496 loop digital audio back this way?

Hello there, 

I would like to ask for some support:

I have a behringer umc1820 and ada8200 config via optical cables.

It works well with drumset mics, but when plug in a bass guitar cable into the ADA Jack slot it comes about a half second of latency in the daw - I am not able to make the bass record, because I touch the strings and the sound comes much later.

In the daw the latency is set to 512ms.

Would you please help me out?

Many thanks, Zoltan

I wonder if anyone can advise me, please, if the Behringer ADA8200 microphone preamp can be internally modified, to bypass the ADAT circuitry? I only need to use the analogue preamps, directly from input front XLRs to the output rear XLRs. I am a competent audio engineer and can solder modify electronic circuits, once I have the diagram. I also am not worried about voiding the warranty. Thank you.
