    UMC204HD connecting multiple client software

    Hi

    Is there a way to route two applications to the UMC204HD output?

    So for instance, I would like to hear the output of my DAW along with the output of say, a YouTube video at the same time? This would then mean I could practice along to a backing track without needing to import an extra track in the DAW.

    Kindest regards

    Can anyone from Behringer reacto to this? I have same problem. My previous interface was Tascam US 322 and its multiclient driver allowed to work in a DAW on Tascam's ASIO while being able to listen to Youtube, Soundcloud etc. without closing the DAW program, for quick referencing. Now I moved to UMC 202 HD and while sound quality is clearly superior, it's a giant leap backwards driver - wise. FIX THE DRIVERS.

    UMC404HD has same issue

    I just posted a similar question for the UMC404HD. Any help is appreciated.

    Hello Garrett, Marius and Paul,

    I had similar problems directly after buying the device and attaching it to my system. The problem here is obviously caused by multiple applications which use different bit depths and sample rates.

    As far as I could research it, the device driver of the UMC usually converts different sample rates to the one which is set for the output channel. This is called sample rate conversion (SRC). I saw several postings on the net which state that this worked well until Microsoft rolled out the Windows 10 build 1803 spring patch. After this, the sample rate conversion was broken, the postings stated.

    YouTube, for example, uses 44.1kHz sample rate while your DAW will probably use 192kHz. As the driver's SRC doesn't work anymore after Build 1803 got installed, it can't convert the rate of the 2nd application and thus, you won't be able to listen to it (if my assumption is correct - if not, please correct me directly).

    I can't reproduce the pre-build1803 behaviour of the UMC404, because the patch already was installed on my system when I bought and attached the device.

    What helped me to rid the problems completely was to set a fixed output playback sample rate of 44.1khz (24bit) in the Windows sound properties.

    Open up the Windows sound properties control and chose the 'Playback' tab. Double click the input device you want to change (on my system, it's 'Line Out 1-2'). In the device properties, chose the 'Advanced' tab. You will see a drop down field with the setting '2 channel, xxbit, xxxxx Hz (xxxx quality)' or similar.

    Click on the down-arrow right next to this drop down field - it will give you a list of possible bit depth / sample rate combinations. Chose '2 channels, 24bit, 44100 Hz' here, then click OK two times. Restart the system to close / initialize any opened application handles / drivers. Now, start your DAW and a YouTube video and examine if both sounds are played.

    Hope this helps - please leave me a feedback here and tell me if it worked out, thanks.

    This is not a driver problem alone, the problem here is in my humble opinion that MS changes a lot with every new Windows build (they publish those twice a year) and thus, breaks the funcionality of many hardware devices.

    If one of the Behringer developers should read this - it would be awesome if you could test this driver for compatibility to Windows 10 Build 1803 and revise it. Thanks in advance for this!

    Kind regards,
    Fritz

    Hi,

    I just wanted to give you an update.

    I fiddled a bit more with the sound settings. I set them back to 192kHz in the Windows sound control. Then I started a Youtube video which ran fine. Now I started my DAW which stopped the vid immediately.

    Youtube doesn't run at 44.1kHz but adopts the bit depth / sample rate of the system. In my case the DAW was the problem. It obviously sets it's own sample rate which breaks the video streaming.

    I changed my DAW's standard sample rate to 192kHz, closed the DAW and the browser and started them again. Now both the video and the DAW run fine without any errors. I will leave the settings as they are and run a few recording tests but upto now everything looks ok.

    So I guess the main cause of problems like these are imho just different sample rates in different applications. Change the sample rate and bit depth in your applications to the same setting as in the Windows control.

    The UMC driver seems to be fine so far and runs smoothly with Windows 10 Build 1803.

    Kind regards,
    Fritz

    I'll tell you this definitely isn't a problem with the ASIO4ALL driver designated to be used with our UMC204HD interfaces, as those are compatible with the latest builds of Windows 10. (including 1803)

    I'd take a look at Fritz's comments above as he provides some accurate information on this topic. In addition I'll add the following:

    When using only one audio program under Windows, the used driver decides the sample rate.
    If the audio application uses the Windows Sound Devices driver part (browser, media player, etc.), then Windows decides the sample rate, as shown / pre-selected on the Sound settings panel of Windows.

    If an audio application uses the (UMC) ASIO driver, this driver decides the sample rate.

    In the special case where 2 applications want to access the same hardware (UMC output), it “could” work by default, but only if both applications (WDM and ASIO) are already set to the same sampling rate. But if they are not set to the same, then the ASIO driver will have priority and the other application (which is using the Windows driver model) will not work.

    The reason is quite simple - an audio device such as an USB audio interface needs a clear defined sample rate to operate properly. If 2 different applications want to access it, the hardware would not know what to do, so an actively running ASIO-driver has generally priority. The UMC driver can NOT do sample rate conversion, and never has been able to in the past.

    Also good to know:
    Even when changing the sample rate inside a typical WDM application (such as Audacity), this will not affect the connected USB audio interface! The audio hardware will always be fed by the Windows sound device driver part. So, for example, when Audacity is set to 96 KHz, but at the Windows Sound panel is 48 kHz selected, Windows will do a sample rate conversion from 96 to 48 kHz and playback at 48 kHz via the USB audio interface. But this will not work for ASIO applications or when 2 different audio applications are running in parallel.

    Hope this information is helpful to you and anyone else here in the forum trying to playback multiple audio sources from different audio programs to one dedicated audio interface.

    Forget it guys. I just logged to say I've fixed but Fritz nailed the problem 10 out of 10.

    If your soundcloud/youtube don't work when you have your sequencer up running U-Phoria's ASIO, the problem is the sample rate difference among various applications.

    I just ran the "fix sound problems" and it auto - corrected the "non default" samplerate set in Windows to 44100 hz. Why it was set to other value before - Idk.

    Thanks all for taking time to look into this and reply.
