=== latency_multiplier 8 min_grant_clocks 72, max_latency_clocks 0 min_grant_clocks 0, max_latency_clocks 640 min_grant_clocks 16, max_latency_clocks 192 min_grant_clocks 0, max_latency_clocks 0 min_grant_clocks 160, max_latency_clocks 320 min_grant_clocks 128, max_latency_clocks 272 sum of minimum grants 376 lowest latency allowed 192 ==== According to that last URL your situation is hopeless, because the sound device says it can't wait more than 192 ticks, before being serviced and if the guy with 160 and 128 happen to come along the sound card has hard to wait too long. I personally think that is bogus... there has got to be a way to have them play along. I don't expect this to work... but try it and let me know what the results are: ==== # "open up" the PCI bus by allowing fairly long bursts for all devices, # increasing performance setpci -v -d *:* latency_timer=b0 # maximize latency timers for network and audio, allowing them to transmit # more data per burst, preventing buffer over/underrun conditions setpci -v -s 02:04.0 latency_timer=ff setpci -v -s 02:06.0 latency_timer=ff === that advice comes from the following URL: http://www-106.ibm.com/developerworks/library/l-hw2.html Basically if it doesn't work I'd like to try some other settings. Let me know, Mike ps: it's remotely possible your machine will lockup when you run those set PCI commands, so be sure to save anything important. _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
