Sound does not work in reboot from openSUSE to Windows 7

Hi everyone,

I am experiencing some trouble with a dual-boot configuration running openSUSE and Windows 7 plus a few other linux distros. More specifically, when I reboot from openSUSE, and then boot into Windows 7, I can’t get any sound in any way from Windows 7. I’ve tried troubleshooting this from Windows and found out that if I power completely off and then boot into Windows 7, or if I reboot into Ubuntu then back into Windows 7, then the sound works. Therefore, I think I have reasonable evidence to conclude that the problem lies in some configuration somewhere in openSUSE.

Does anyone know, based on the symptoms I’ve described, what could be going on, and obviously, how I could fix this?

Thanks in advance,

In which of the supported levels of openSUSE (or maybe even unsupported levels of openSUSE) are we supposed to look for this problem?
And as sound is also very much a case of the individual loged in user and thus of the software (s)he is using, what desktop did the user that was loged in last before the reboot use?

Whenyou read this as mild critic about the important things you forgot to mention, you might be correct :wink:

Right, sorry.

I’m specifically referring to openSUSE 11.4 64-bit edition running the GNOME desktop.

Thanks,

You did not mention the type of computer you are using. I have seen some issues occur when the IRQ (Interrupt) is assigned different between the two Operating Systems. Sometime on a desktop, moving the sound card to a different slot can help. Sometimes, in the PC BIOS setup, there can be a setting saying the Operating System is PNP (Plug ‘N Play) or not, meaning IRQ will be assigned by the BIOS (PNP=NO) or by the OS (Operating System, PNP=YES). Often, I say the OS is not PNP so that IRQ’s will be assigned by the BIOS. Sometimes there is an IRQ setting for Auto or Manual. Sometimes changing this can stop the problem. Sometimes you can delete the driver in Windows and uninstall any associated software. Restart into openSUSE, allow sound to work and then boot into Windows and reinstall said audio software. Somehow, the IRQ assignment between these two OS’ needs to remain the same or not be changed to a conflicting setting in Windows.

Thank You,
