My sound used to work perfectly on windoze, then i installed ubuntu 64 bit which doesnt work anyway, and now the hardware doesnt even show up as unidentified hardware or anything, does anyone know if ubuntu could have done this? And does anyone have 64bit linux working? with a pci express gfx card?

Or there is a strange soundcard named pci express gfx or you are talking about your graphic card.

How do you expect you can be helped if nobody knows anything about your soundcard?

If you are using ALSA, there is a program called "alsaconf" that you run in the console, as root. It will examine your hardware, and if necessary, set up the drivers for it. Also, check if you are a member of the "audio" group. This is needed to gain permission to access the sound device.

If that doesn't work, you will need to supply more infomation. The thing that determines what driver you need is what the controller chip that is used for audio. You can find that out using the "lspci" command.

You had a soundcard going - changed to another distro - distro didn't take so you changed back - soundcard didn't go.

Now, the way you wrote it, it looks like you've changed from windows to ubuntu then back to windows - perhaps you tried a dual boot but Ubuntu didn't take?

It is unlikely that ubuntu would have fiddled the windows settings, since it would be doing everything in different partitions... however, if you were not careful during the install process (like at the partitioning stage) then vital data could have been lost. Remember, windows can put data anywhere!

Cleaning and repartitioning ntfs drives is problematical - so much so that many members here just buy a new hard drive for linux - and the defrag process for vfat based systems (win98) needs to be done from a dos boot to be certain.

To get your soundcard back, probably best to try reinstalling it's drivers. Or, simply(?) reinstalling the OS you want.

If, however, you did a clean install of ubuntu (no other OS) and then a clean reinstall back to the start, then Ubuntu is completely innocent. Look hard at the reinstall.

Now: I see from the sidebar that you have Yoper 2.0 (2.1 is out...) listed as your distro? This "changing OS losing sound" seems often associated with yoper. It seems that yoper is very specialised and changing things around can make for lots of work. This is the price of all that power and speed in a small (single iso) package!

If it is yoper that cannot find the card, as opposed to windows, then the fastest fix would be to reinstall yoper. The install is very fast, probably faster than tracking down the fault to correct it.

Googling this problem for yoper produces lots of promising links to http:\\www.yoper.com ... but I havn't been able to connect. Odd for an active distro.

BTW: "gfx" stands for "graphics" - and your card is listed as a graphics accelerator card. Getting sound out of it would be difficult anyway. Try doing lspci and showing us what *does* happen.

okay the last note was a side question unrelated to the sound, i have a 6600GT & i cant even boot any distro other than windoze, coz they crap out when going into xserver. my sound is onboard realtek ac97 typical audio, so ill try reinstall windows and see if it fixes the problem i was hoping not to have to do this, thnx neway for the replies even tho this wasnt a totally linux problem =)
