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

    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.

    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.

    and all is fine in ubuntu?
    to choose your default device under windows 7:
    -right click the speaker icon on the taskbar
    -left click on "playback devices"
    makes sure you choose the correct default device, if not right then
    -right click the device you want to be default
    -left click on "set as default device".

    if you did this already then i don't know. i don't see why creative would have a driver there and say it works if it doesn't... a quick Google shows people with the card working under Windows 7 (although with other issues instead like no subwoofer output)
    here is a link to a thread discussing that issue, the last post has a solution. maybe it works for you.

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

    This is definitely a clear problem, I've also been using ubuntu for awhile and have just recently switched to 9.10, I had previously been using 9.04 with windows 7 but when I installed 9.10 the sound in windows 7 has stopped working. I have an audigy 2 se card. I have tried restarting the creative audio sound service and a variety of different methods, nothing works

    sound works in ubuntu though. I am running 64-bit btw.

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

    After a while of experimenting this issue, the only "workaround" (if it can be called like that) is to shut down (not reboot, but to SHUT DOWN) the computer, wait a bit, then start Windows 7.

    It's weird tho, I've read somewhere else that there's a problem in the way Ubuntu releases the Sound Card drivers or hardware itself, and when it reboots, Windows can't grab the device. It deactivates it, in some sort of way.

    Turn on PC, boot Windows - Sound Works
    Turn on PC, boot Ubuntu - Sound Works
    Turn on PC, boot Windows, THEN Ubuntu - Sound Works, both times.
    Turn on PC, boot Linux, THEN Windows - Sound Works only in Ubuntu
    Turn on PC, boot Windows, then Linux, THEN Windows - Sound works until 3rd reboot.
    Turn on PC, boot Linux, then Windows, then Linux - Sound works at 1st and at 3rd time.

    If I shut down, no matter what, sound works.

    It's a REALLY strange behavior, don't know who to blame in here. Might be faulty code on any of those ends.

    Running both 32 bit editions of Ubuntu and Windows 7. Note that this wasn't happening back in 9.04, when the sound system wasn't revamped. Coincidence?

    The answer is definitely before or after this post.
