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 . ### BIOS value [0] $ lspci -v 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS690 [Radeon X1200 Series] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
