Dear forum staff and users, recently I have run into an annoying problem concerning the usage of VirtualDub 1.9.11 to capture my screen while using Windows 7.
I have acces to two different systems, firstly a Dell Laptop (Latitude E 5500) that runs an "IDT High Definition Audio CODEC" (V. 6.10.0.6292) on a 32bit version of Windows 7 and secondly a PC with an "ASUS P5Q Deluxe Mainboard" that is calling upon the "SoundMAX 2000B Audio Driver" (V. 6.10.1.6585) and running a 64bit version of Windows 7.
Both Audio drivers enable me to set up an audio loopback and I am able to record each of these loopbacks using audacity. The IDT version goes by the german label "Wiedergabeerfassung" that roughly translates to "playback capture", while the SoundMAX one actually lists the "Stereo Mix" that has been mentioned as a solution in this forum from time to time. VirtualDub however is trying its best to convince me that there are "no audio inputs", even if the Stereomix is set to be the standard recording device and the only one left active.
It would be great if you have any idea on how to solve this problem, or at least an idea about where to start looking for a solution.
Looking forward to your replies. |

This means that VirtualDub is unable to see the sound mixer inputs. If you can still set the recording input in the Windows Volume Mixer, you should be good to go as that should also apply to your capture.

Thanks for the tip phaeron.
It seems to basically work as you described it, however I still have to solve some problems with the audio sync. In XP I deactivated it alltogether and everything was fine, this time around it seems as if I have to come up with a diferent sollution, but for now I have at least somewhere to start the finetuning.
Sincerely yours Alf_42 |

Hi,
I guess this topic comes closest to my problem, which is very similar.
I used to do some screen capturing with VDub, mainly from DosBox, working just fine. Recently I did some capturing from my EZCap-USB device, also worked quite well. But now, for some reason, all the audio devices are gone in screen capture mode.
More specific: if my capture device is put on the USB grabber, everything is fine with the audio sources, I can choose between Stereomix (which I usually chose for screen capturing) or Line-in (Audio from the USB-grabber). But as soon as I change the capture device to screen capture, all that is left in the audio devices is something called "wave mapper", that produces no sound at all in the recorded file.
The strange thing is, I didn't change anything, no new soft- oder hardware, not even a different driver. I used to switch between the USB device and screen capture regularly and it always worked just great. It seems that VDub just suddenly decided "no audio for you in screen capture any more". I don't know what the hell happened.
Also, the above mentioned Windows volume mixer hasn't changed either, just like my realtek mixer as well. Everything is where it should be (stereo mix, etc.) and seems to be in order.
I'm using Virtualdub 1.9.8 on Win7 x64 with a realtek onboard sound device on a gigabyte EX58-UD4P mainboard. Please help! |

The screen capture minidriver uses a different method of picking up audio inputs than the DirectShow driver, so it's possible that the mixer lines are inaccessible for some reason. "Wave mapper" simply means the default recording device, so you should be able to modify the system settings to make this work. I'll check if something's happened in Windows 7 with the mixer API, though.
Also, is there a reason that you're screen capping DOSBox instead of just using its built-in video recording feature? You'll get MUCH better quality and performance that way with its built-in ZMBV codec.

I'm recording commentary from a mic simultaneously and I don't want to set up an extra audio recording for that, because I'm too lazy to do the sync work.
Another point is, I don't like the usability of dosbox' recording device, and I capture mostly from dosbox, but not exclusively. Plus, the built-in codec isn't suitable for my encoding purposes.
So I understand there's a possibility to make that wave mapper thing work as my sound device? But what could be the reason that stereomix just disappeared all of a sudden? |

I did some investigation on this last week and it looks like there was a change to the mixer support in Windows Vista that broke VirtualDub's ability to see the mixer audio inputs. You can still record, but VirtualDub won't be able to show or change the selected input. I don't know yet if this was intentional to prevent programs from mucking with the recording input or if there is a fix I can make on my end. Current versions of VirtualDub are able to launch the Windows 7 recording control panel properly and that will allow you to change the input.
Alternatively, you can try the test build in the Testing Forum that has support for DXGI Output Duplication and WASAPI loopback capture. The latter is what you are interested in and will allow capturing the computer's output on Windows Vista and later even if there is no Stereo Mix input from the sound driver.

Hey, cool, thanks. I appreciate the help. I have tried to find the windows record panel in the lates version, but still it's the same thing.
What I don't get is that I do keep seeing the stereomix as long as I have the USB grabber picked. It only disappears when I pick screen capture. Even with the new version. Is there some kind of settings file that I have to delete seperately? Cause it seems that all my prefs are still the same although I exchanged the program version. I'm really confused by now :/ |

To get to the recording settings in Windows 7, right-click on the speaker icon in the notification area and select Recording Devices.
You're likely getting those inputs with the USB grabber because DirectShow is showing those inputs, whereas the Screen Grabber code is Windows Multimedia based. Don't know yet why the difference in behavior exists. This is not a VirtualDub settings issue, it's a issue with two different sound APIs in Windows.

I just recently learned this:
Right click on empty white space below the list of your devices.
Enable the two options.
Then try enabling your desired input (stereo mix), if it exists.
