read the above thread, is about a gateway but, the instructions especially for cleaning all the bits of the driver out of the system
https://support.toshiba.com/search/xp sound driver for Toshiba Satellite r15-s829
go to above and input your model number or serial number to see if you can get an xp driver for sound, the only operating system listed for that satellite is Vista.
are you able to boot to safe mode to uninstall the sound driver?
