ubuntu 9.10 64bit dual boot with windows 7 64bit - sound problem

[h0ffmeister]

Hi there,

I've been a long time reader but this is my first post. I have a problem with a new machine I have been building. I've been using Ubuntu for years and decided to build a Windows 7/Ubuntu 9.10 dual boot machine to consolidate my PCs.

I installed windows 7 home premium on a dedicated hard disk. All went fine and did windows update to solve driver issues. At this point I had sound. I then installed ubuntu 9.10 on a separate physical disk without issue. Ubuntu installed Grub which recognised windows 7 and I could boot into both OSes, both working happily, including sound. I then installed some apps in ubuntu (incl. wine and spotify) and now when I boot into windows 7, I don't have any sound. The sound icon is happy, the device manager is happy. I haven't touched the windows disk or installation, yet the sound doesn't work. The sound hardware is a Sound Blaster Audigy PCI card. To get Spotify to behave under wine, I set the Audio to be OSS instead of ALSA and use hardware emulation.

Surely making changes in Ubuntu on its own separate physical disk should have no effect on a Windows 7 installation on a different disk?

Any advice/ideas?

Thanks,

H0ff.

Hi,

I can only assume that something is happening at the OSS/ALSA level with the card which somehow affects the way the Windows 7 driver communicates with the device. I also found this unfortunately:

Sound Blaster Audigy SE OEM

I didn't even consider this as I tested Windows 7 Ultimate eval for a few weeks on the same hardware without any problems. I only got issues when I dual booted. I've decided to get another sound card - one that is compatible with Windows 7:

Sound Blaster X-Fi Extreme PCI-e

Thanks a lot Microsoft!

It still doesn't explain why it worked and then stopped when I did "sound" things in Ubuntu.

but there is a windows 7 dirver for that card
try installing it and maybe this takes care of the problem under Win 7.

[h0ffmeister]

Already tried that. Uninstalled the Windows Update one and installed the Creative one - still no sound.

are you sure its your default device? win 7 is much like the new sound preferences in Karmic and you have to choose your default device to get sound there.

Yes, definitely default device.
