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>
|

|
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.
