Identifying and removing unknown Sound device Since I use my Mac for presentations at workshops and conferences, I've apparently picked up a whole bunch of "exotic" drivers that come as part of presentation AV equipment. The latest addition seems to be the "Data Source Item 0" in the Sounds-drop down. I think I found the culprit in the Audio MIDI Setup (at least there's an audio driver from one of those AV-rooms), but the - button is not available for any device.

How do I go about identifying where this is coming from and removing it?



As @Allan suggested, system profile below -- how would I go about axing the ESHOW-device:

$ system_profiler SPAudioDataType
Audio:

    Devices:

        Built-in Microphone:

          Input Channels: 2
          Manufacturer: Apple Inc.
          Current SampleRate: 44100
          Transport: Built-in
          Input Source: Internal Microphone

        Built-in Output:

          Default System Output Device: Yes
          Manufacturer: Apple Inc.
          Output Channels: 2
          Current SampleRate: 44100
          Transport: Built-in
          Output Source: Internal Speakers

        ESHOW录音:

          Default Input Device: Yes
          Default Output Device: Yes
          Input Channels: 2
          Manufacturer: Apple Inc.
          Output Channels: 2
          Current SampleRate: 44100
          Transport: Virtual
          Input Source: Data Source Item 0
          Output Source: Data Source Item 0
I also suffered from this problem after installing a software to use a wireless projector. Though the name is not ESHOW but DongleAudio in my case, I guess this works for you.


In Terminal.app, cd /Library/Audio/Plug-Ins/HAL
Remove the driver by rm -rf ESHOW.driver or rm -rf DongleAudio.driver
Reboot your Mac


I hope this helps.
