Plug & Play O/S was [No] now it's [Yes]
Resources Controlled By was [Auto] now it's [Manual]
But this enables to assign only unimportant/unused IRQs, so I didn't
change the settings.
PCI Latency Timer (CLK) was [64] now it's [0]
*** PCI Express relative items ***
Maximum Playload size [4096] the max value
With latency timer set to 0 nothing seems to be different, I already
hear xruns while writing this mail. lspci does confirm that the RME
card is set to latency 0, but the other cards still have higher values,
so I set PCI Latency Timer (CLK) to the max [255]. No soundcheck,
regarding to lspci it's more worse than before, so I'll reboot now and
restore the default value [64] and then write a script as explained by
http://www.mythtv.org/wiki/PCI_Latency .
