This problem was reported several times in the -mobile. The sound has delay normally. Most interesting thing is when the I move usb mouse fast or has a high network load, the sound become better. I think the problem is related to the IRQ dispatch. When I use systat->vmstat, I found the interrupt number for pcm0 is large when I move mouse fast. Who can give me some advice? Or produce a path I can try. BTW: I can not find the usb driver and fxp0 in the list of the systat-vmstat. In my machine, IRQ 9 is shared with several devices, as listed in the following dmesg. agp0: mem 0xe0000000-0xe007ffff,0xe8000000-0xefffffff irq 9 at device 2.0 on pci0 uhci0: port 0x1800-0x181f irq 9 at device 29.0 on pci0 uhci1: port 0x1820-0x183f irq 9 at device 29.1 on pci0 uhci2: port 0x1840-0x185f at device 29.2 on pci0 pcib0: possible interrupts: 9 fxp0: port 0x3000-0x303f mem 0xe0204000-0xe0204fff irq 9 at device 8.0 on pci2 pcm0: port 0x18c0-0x18ff,0x1c00-0x1cff irq 9 at device 31.5 on pci0 uname -v FreeBSD 5.0-CURRENT #14: Sat Mar 15 18:28:01 CST 2003 junsu@junsufr.gwbn.sh.cn:/usr/obj/usr/src/sys/VAIO Jun Su _________________________________________________________ Do You Yahoo!? 更多惊喜，同样精彩，NetVista A30 热卖 http://ad.cn.doubleclick.net/clk;5313999;7930402;p?http://www.ibm.com/cn/promotion/pc/netvista_a30/index.shtml To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
