recording in serato with djm-s11

I've heard a rumour that there's an issue with Serato's recording function since 2.4.1, but out of curiosity, have you set a recording output in the S11 Setting Utility?

Still the same problem, I even stall driver on my PC windows 10, went the settings utility, made sure everything was set, same problem on the pc windows 10, and macbook pro OS 10.10 Yosemite

Running serato 2.4.2 on Both pc and mac

Well, for starters, it won't run on your Yosemite computer, so please consider upgrading to 10.13 (High Sierra), 10.14 (Mojave), or 10.15 (Catalina).

I'll pass this to our product team for further investigation.

Have you allowed Serato access to the mic in the System Preferences > Security & Privacy > Privacy > Mic:

I had that problem also..  it was a problem on my record location..
