Toshiba S703, sound interupts system in SuSE, Fedora C1

I have a toshiba S703 and I have almost the same problem under Fedora C1 as I did under Suse 9.0. Whenever the sound is enabled, mplayer, games, alsa, etc. the sound plays back choppy and the disk constantly cycles on and off while it is accessing the file. It almost seems like an interupt conflict on the 810 bridge, I could be way off.
Under Suse I had to roll back to an older kernel, found the help on this board, and that worked, but I can't get all the programs to run on Suse like I can on Fedora.
Is their anyway to manually configure the sound module and it's settings (DMA, IRQ, etc.) even though this system is pretty well set up through the ACPI? Am I even on the write track.
Any help would be appreciated. I am trying my hardest to get this thing to work.

I have learned the following. If I run mplayer form the command line (No X interface running) I get errors that start with
ohci1394_0: (I cant remember the text right now, on Windows, but some things to do with interrupts, etc.)
the sound runs for a moment, pauses, the disk accesses itself, the music starts back up for a moment, and this goes on.
Alsaplayer ***.mp3 from the command line really kills the system. If I run alsaplayer in Gnome it goes through this process without even loading a file.

Help is greatly appreciated.

I had the same problem with my 705 running suse 9.0. I found the problem to be that the firewire card and sound card was trying to run on irq 10. I do not use firewire under linux so I just disabled it and now everything is working fine and dandy. Check out this tread:
