MATLAB: Error using audiorecorder/resume (line 609) Device Error: Unanticipated host error

audio record

Hi,
I've been using a script for a while for recording audio. The script has worked without problems for a while now. Strangely, today I've started getting an error message:
" Error using audiorecorder/resume (line 609) Device Error: Unanticipated host error
Error in audiorecorder/record (line 653) resume(obj); "
I've tried the code with the external audio card (Xonar U7) I've been using and which the script has worked with before, and with-out (connecting directly to the motherboard microphone jack), but I get the same error message.
The audiorecorder object currently: "arec =
audiorecorder with properties:
          SampleRate: 48000
       BitsPerSample: 16
    NumberOfChannels: 2
            DeviceID: 1
       CurrentSample: 1
        TotalSamples: 0
             Running: 'off'
            StartFcn: []
             StopFcn: []
            TimerFcn: []
         TimerPeriod: 0.0500
                 Tag: ''
            UserData: []
                Type: 'audiorecorder'"
And the command that initiates the error is simply:
record(arec)
OS: Windows 10.
audiodevinfo:
>> info.input.Name
ans =
Primary Sound Capture Driver (Windows DirectSound)
ans =
Microphone (Realtek High Definition Audio) (Windows DirectSound)
>> info.input.DriverVersion
ans =
Windows DirectSound
ans =
Windows DirectSound
>> info.input.ID
ans =
       0
ans =
       1
Any idea what's going on???
Thanks, Iftach

I had the same problem on Windows 10 and it turned out that all the inputs were blocked by the "microphone privacy" settings, which I had turned off earlier. Turning them on again (while keeping off the unwanted software) solved it.
