Topic: SC2900 no audio
I've just swapped to a new W10 laptop (from W7) and changing to VDJ2018. I'm struggling to get audio via the SC2900s.

So, I've clicked "Use Soundcard" at the Startup screen.

Audio settings are as below


Deck 1 plays through the laptop speaker. Deck 2, no audio from anywhere. The track does 'play' though, unlike V7.4 when the settings are in-correct.

I'm guessing I'm missing something real simple/silly.

Any help appreciated.

Note, MIDI control functions operting as expected. i.e. Play, Cue, Scroll, Select, Pitch, etc etc

It appears that you are using a old/outdated Build of VirtualDJ. Can you please update to the latest available and see if that is still the case ?

If still an issue, can you please follow the steps below and provide the asked info ?

- Open VirtualDJ, goto Settings, OPTIONS tab and set createMidilog to Yes
- Close VirtualDJ
- Delete the file Log report.txt from Documents/VirtualDJ folder
- Make sure your SC2900 is connected and open VirtualDJ
- Close VirtualDJ
- Post here the content of the Log report.txt file you find in Documents/VirtualDJ folder

Did you install the ASIO driver? Assuming of course that the driver (and your Windows) is 64 bit.

Even if not, you shouldn't have "internal soundcard" selected, because the SC2900 is not internal... Is the SC2900 not listed on the drop down audio interface selection?

Will do this as soon as I can.

According to VDJ online setup manual (for sc2900) "Denon ASIO not to be used, due to instability issues". Use windows WASAPI instead. However, I thought it odd that USB soundcard is not select-able.
Should I download the Denon ASIO driver, a genric ASIO driver (if that's even possible) or something else?

Thanks both for your help

Ah, well in that case don't use it! The SC2900 should still be visible to your OS as an audio interface though...

That's pretty weird.. without the ASIO driver installed, there doesn't seem to offer any WASAPI driver, so there is no ..
Audio device found: .... Denon device entry.
Therefor you shouldn't get any Denon entry in Windows Device Manager under "Audio inputs and outputs" either, right ?

This means that you have to install the Denon ASIO driver from Denon legacy downloads (https://www.denondj.com/downloads#legacy - scroll down to SC2900, ASIO driver 2.22)

After you install, there should be (hopefully) a button for Denon SC2900.

Please repeat the procedure above after installing the ASIO driver and provide the content of the Log Report.txt. Really curious to see if the WASAPI will be there now.
