Solved hotkey to disable an audio device of choice

[fohrums]

How would I add a hotkey to toggle on/off an audio device of choice in Windows 7 x64?

Here is an image of Windows 7 sound dialog window > playback tab to audio devices.

reason being: skype doesn't have a default audio device as an option so I switch between headphone (reciever) to speaker (PC creative sound card) with a hotkey I defined already using NirCmd. problem is skype doesn't switch along with it. my method is to disable an audio device so that way the next one is effective in skype. complicated but it's the best and only way I can think of without making it TOO complicated as it is already.

When I plug headphones in, the speaker is cut off. I have not tried this with Skype but will as soon as I can.

By default the way skype would be designed along with windows 7 architecture (i'm really dumbing this down :sarc ofcourse plugging it in would then use the headphones and speakers are cut off.

I use two seperate/different outputs. As I mentioned an external reciever for my headphones and my desktop speakers are connected via creative sound card which I have installed PCI-E. so a lot of manual work is needed to necessarily transition that sound without any interference.

All I can suggest then is to use a program like regmon to see what is being changed in the registry when you disable/enable, then write a small batch file to make the necessary registry changes as needed, one to disable and one to enable.

It's no longer available and been replaced by "ProcessMonitor" I don't know how to use it to get the registry keys needed. Perhaps show me some example on how to use it or if possible find it out?

I use Audio Switcher. There's no hot key. But it sits in the tray and lets you click-choose from the available audio devices.

I figured out how to focus on a window's processes by using the crosshair tool (8th from the left of toolbar). Simply drag it to the window you want to focus on.

PROBLEM IS: I can't figure out how to put this into action or so you said "batch file" to have this be applied to a hotkey via shortcut.

So basically by right clicking on an audio device these are the registry keys in use:

when I make the action to "disable" these are these are the registry keys in use:

Yes, "choose" is already what I've mentioned binded to a hotkey with NirCmd. I specifically and only want a hotkey to "Disable"

Using audio switcher just adds to the ram as it's necessarily running in the background for a quick task that I don't find myself switching that much too often.

atleast with batch files it's there until you run it not using any resources in the meantime what so ever.

You would have to write the batch file to apply the registry changes, then setup a hotkey to invoke the batch file.

The Open and Set registry actions indicate the key you need to modify. After disabling, go into regedit and export that key. Do it again after you enable it again.

That should give you the registry changes you need to apply.

No.

I can't emphasis this enough. keyword: "Disable"

In other words. I'm looking for a way to "Disable" (turn off) a device. I mentioned twice that I have a hotkey to switch audio devices already using NirCmd in which from that command-line tool i'm able to set between (or all) which device I want as default device and communication device, etc.

thanks what I did was found which of the 4 I highlighted made the change and it was the one listed with the description changing the DWORD value. How I made I signed it to a hotkey was sending it to desktop (as shortcut) and right-click properties to define the key combination.

only problem now is that it's always verifying yes/no if I want to go forth with the action. How do I disable that security? I tested it out and know it's safe.

How are you applying the change? Are you using the reg command? If so, looks like the /F parameter is what you need.

C:\Users\rrkurtz>reg add /?

REG ADD KeyName [/v ValueName | /ve] [/t Type] [/s Separator] [/d Data] [/f]
[/reg:32 | /reg:64]

KeyName [\\Machine\]FullKey
Machine Name of remote machine - omitting defaults to the
current machine. Only HKLM and HKU are available on remote
machines.
FullKey ROOTKEY\SubKey
ROOTKEY [ HKLM | HKCU | HKCR | HKU | HKCC ]
SubKey The full name of a registry key under the selected ROOTKEY.

/v The value name, under the selected Key, to add.

/ve adds an empty value name (Default) for the key.

/t RegKey data types
[ REG_SZ | REG_MULTI_SZ | REG_EXPAND_SZ |
REG_DWORD | REG_QWORD | REG_BINARY | REG_NONE ]
If omitted, REG_SZ is assumed.

/s Specify one character that you use as the separator in your data
string for REG_MULTI_SZ. If omitted, use "\0" as the separator.

/d The data to assign to the registry ValueName being added.

/f Force overwriting the existing registry entry without prompt.

/reg:32 Specifies the key should be accessed using the 32-bit registry view.

/reg:64 Specifies the key should be accessed using the 64-bit registry view.

Examples:

REG ADD \\ABC\HKLM\Software\MyCo
Adds a key HKLM\Software\MyCo on remote machine ABC

REG ADD HKLM\Software\MyCo /v Data /t REG_BINARY /d fe340ead
Adds a value (name: Data, type: REG_BINARY, data: fe340ead)

REG ADD HKLM\Software\MyCo /v MRU /t REG_MULTI_SZ /d fax\0mail
Adds a value (name: MRU, type: REG_MULTI_SZ, data: fax\0mail\0\0)

REG ADD HKLM\Software\MyCo /v Path /t REG_EXPAND_SZ /d ^%systemroot^%
Adds a value (name: Path, type: REG_EXPAND_SZ, data: %systemroot%)
Notice: Use the caret symbol ( ^ ) inside the expand string

I see, so forcing it using /f command.

Problem is skype doesn't recognize the change and I have to still manually switch the output so it doesn't matter. I ended up not needing this method.

Appreciate the help, hopefully others read and value that.

Ah well, it was worth a try.
