It might be valid, but probably best to mark as won't fix for now since this is hard to reproduce and too difficult to determine where the bug actually lies (Windows or LMMS).

I had this issue too. Windows 7 32-bit, LMMS 0.4.15 x86, x64, LMMS 1.0.0 x86, x64. The cause in my case was a bug or misconfiguration with the Conexant Audio Driver supplied from the factory from Toshiba on a Satellite S5200 laptop.

Microsoft Visual C++ Runtime Library
This application has requested the Runtime to terminate in an unusual way. Please contact the applications support team...
Details: libportaudio-2.dll

I would recommend:

1. Open Device Manager
2. Expand Sound and Game controllers
3. Locate your sound card, Right Click, Remove Device
4. Click the Checkbox that says "Remove driver software for this device"
5. Reboot
6. Windows should automatically search for a sound driver. This will take a few minutes.
7. Windows should install a sound driver from Windows updates. Once finished, reboot if needed.
8. If Windows could not located a sound driver, visit the manufacturer website and manually download a sound driver for your computer, install the sound driver manually, reboot if needed.
9. Try LMMS again.

I would suspect there is an avoidable bug where LMMS is trying to access features of the sound driver that aren't available. This will continue to happen, so we need to provide a way to our Windows users to provide us logs so perhaps we can understand exactly why this is happening.

I posted on the sf.net bug as that was what came up in google for me when searching for the issue https://sourceforge.net/p/lmms/bugs/550/ I was asked to link from here.

I've tried the solution suggested by tresf, removing and installing updated sound drivers. But it didn't change anything with LMMS (although I do have a shiny new interface for my sound card settings now...)

The screenshots are from the win64 build, but identical errors came up with the win32 build. I also have Razer's virtual surround sound drivers installed, but I got identical results after disabling them.

I have jack running (using portaudio_x86.dll) as well, but it seems to have no effect on the issue.

edit: I just tried using the win32 build with the portaudio dll from portaudiosharp, and it works! I'd still like to get the win64 version working as well, though...

Thanks for posting this. When you say you have updated sound drivers are they from the manufacturer or Windows update? In the case of my fix, we needed the Windows update drivers (which I understand are inferior to the manufacturers supplied ones).

To install the Windows update drivers, Windows Update Driver Searching needed to be enabled, and the original driver had to be removed and uninstalled using the "Remove device driver" checkbox in the confirmation dialog upon removal from Device Manager as per the instructions I offered above.

Can you post some details about your hardware? Hardware details may shed some light down the road on why certain people are experiencing this whereas other people are not experiencing this.

You may also want to rename your %USERPROFILE%/.lmmsrc.xml in between trials.

Last, this is fairly obvious but any virus scanning you can do on the PC to ensure the DLLs aren't infected would be of benefit as well.

After rebooting with the drivers uninstalled (following the instructions above, including the checkbox), some generic audio drivers were installed by windows. I tested at that point, and it still wasn't working. I then went to the Realtek site and got the latest Realtek drivers installed, rebooted again, and it's still not working. I haven't been downloading any .dll files from random places (at least not for sound, I've also been trying to get a prodikeys keyboard working on win7 x64, which has gone nowhere...).

Thanks for the location of the config file, I wasn't able to find anything other than the directory before.

I'll be able to test again later and post hardware specs, after sleeping perhaps. I'm also idling in the IRC channel if that would help.

This worked for me:

1. Download "PortAudio.dll" from https://code.google.com/p/portaudiosharp/ and rename it to "libportaudio-2.dll"
2. Browse to "C:\Program Files (x86)\LMMS" and replace the existing "libportaudio-2.dll" with the one you just renamed.
