[ltp] Help for a newbie

[linux-thinkpad@linux-thinkpad.org]

I've seen slow motion sound after a simple reboot from Windows into Linux! 
Check this first! 
  
I needed to shut completely down then restart to avoid this.  
  
These settings work well with the CS4237 sound chip and a Thinkpad 380Z...maybe  
with your thinkpad too.  
  
 
 1) Disable Plug N Play function in Thinkpad BIOS by 
 shutting off quick boot option. 
  
 2) Run sndconfig in superuser terminal using values for CS423X: 
 io=530, irq= 5, dma=1, dma2=3, mpu io=330, mpu irq=9. 
 
 3) Log on as root, in file:/etc/pcmcia/config.opts edit 
 as a comment by placing # in frount of line: 
 
 include port 0x100-0x4ff, port 0xc00-0xcff 
 
 4) In KDE control panel, set sound server to start at 
 boot, using autodetect settings. 
  
 5) use Kmix to set & save volumes.
