I am trying to use an appliance which is based on Fedora 15 for an online study course I am doing. I am using a MacBook Pro and hosting the Linux on Parallels Desktop 7.

My issue is that I have no sound when trying to play an MP3 file or a YouTube clip on a Firefox browser.

I checked the RPM package files and they are all for the .i686 architecture. I'm 90% sure that the MacBook Pro processor is x86-64. My thinking is if I get x86-64 applications I will get sound.

My question is what is the best way to go to swap the RPM applications to x86_64? Do I remove the i686 applications then install a fresh package for x86_64. Do I just do an upgrade using x86-64?

Thank you

Check to ensure processor IS 64 bit http://www.cyberciti.biz/faq/linux-h...64-bit-or-not/.
You can use that page to see if you've got a 64bit OS also.
If you have 64bit HW, but 32bit OS, you'll need to re-install a 64bit OS; you cannot 'upgrade' to 64 bit.

I doubt that upgrading 23->64 bit will solve the sound issue, but no harm in getting 64 bit if your HW supports it.
RHEL based systems will handle 64 & 32 bit apps on a 64 bit OS.

Thanks chrism01. I have confirmed I have a 64bit CPU and the OS kernal is 32bit.

I'm still working on the sound issue.

fedora dose not and never will support mp3 "out of the box"
please read the fedora documentation
