Hmmm....after Googling that error message, it seems like this is not localized to your HP program. But it might be localized to Windows 7. Not sure.
You might try running the program in compatibility mode. If that doesn't work and you can't find any other solution, you might just have to do a System Restore (assuming you have a useful restore point).
I found where you posted on another forum with this same issue. I wouldn't worry about personally. Like that other person said, if your drivers are messed up, you'll know. And I mean, it's not like at xx/xx/xxxx specific date, this audio driver will stop working and your computer will have a bsod until you update it. It doesn't work like that. You might encounter one that is old and is incompatible with a new program or something, but a computer can work indefinitely with the exact same hardware, software, drivers, etc.....the driver may be old, but if it worked yesterday, it will work tomorrow. See what I mean? You're more likely to have a problem with a new, poorly written driver than you are with your old, faithful drivers. And Windows Update will let you know if there is an important new one out there, anyway.
You can fiddle with it to try and get it back, but I personally wouldn't worry about it.
Good luck, though.
