+NAME
+oss_ich - Intel ICH/SiS7012/Nvidia/AMD audio device driver.
+
+DESCRIPTION
+Open Sound System driver for Intel ICH, nVidia Nforce, AMD and SiS 7012
+devices.
+
+OPTIONS
+
+o intelpci_rate_tuning=<NNN> (default is 240)
+ Some Compaq Deskpro models (EN and EX at least) and certain Dell models
+ play and record audio at a higher speed than what is expected. If you have
+ an Intel815 motherboard with an AD1885 you can try setting the parameter
+ to 240, 280 or 330 and see which works for your system. The way to figure
+ out the the right intelpci_rate_tuning value is using the osstest application.
+ It reports a sample rate drift value ("Sample rate drift" or "srate drift").
+ Use the following formula (round the result to the nearest integer):
+
+ <intelpci_rate_tuning = (240*(drift+100))/100>
+
+o intelpci_force_mmio=<0|1> (default is 0=Disable)
+ This option can be used to force the ICH4/ICH5 and ICH6 controllers to
+ run in memory mapped mode to free up I/O address space.
+
+o ich_jacksense=<0|1> (default is 0)
+ Force use of jacksensing on some AD198x mixers.
