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

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 am experiencing a similar problem with an external microphone connected via a USB port. I have tried using PsychPortAudio functions from Psychtoolbox instead, but it still failed. Recording via the standart Windows recorder works though. It would be great to hear about possible solutions!

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.

Great! Never thought about that, thanks!

if your system is mute, just unmute it.
