Sorry about that last post.
Info: I am running Ubuntu Desktop 14.04 in VM workstation.
Question: I want to disable all and only the input sound devices and keep the output devices. I cannot find an option under sound setting GUI to do this.
Reason: I don't have a microphone plugged into my computer. If Ubuntu tries to access input sound device when I don't have an input device on my host (Windows 7), then VMware workstation would say "Device ID out of range, sound adapter will be disconnected." This will disconnect both the input and output device (because it is in one VMWare virtualized sound adapter). I want to get output, and don't want the sound adapter to disconnect.
Things I have tried: Muting all the input devices doesn't work.
