Hi All, Since the sound in my lap (SONY R505) doesn't work, I did some troubleshooting. 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: <Intel 82830M (830M GMCH) SVGA controller> mem 0xe0000000-0xe007ffff,0xe8000000-0xefffffff irq 9 at device 2.0 on pci0 uhci0: <Intel 82801CA/CAM (ICH3) USB controller USB-A> port 0x1800-0x181f irq 9 at device 29.0 on pci0 uhci1: <Intel 82801CA/CAM (ICH3) USB controller USB-B> port 0x1820-0x183f irq 9 at device 29.1 on pci0 uhci2: <Intel 82801CA/CAM (ICH3) USB controller USB-C> port 0x1840-0x185f at device 29.2 on pci0 pcib0: possible interrupts: 9 fxp0: <Intel 82801CAM (ICH3) Pro/100 VE Ethernet> port 0x3000-0x303f mem 0xe0204000-0xe0204fff irq 9 at device 8.0 on pci2 pcm0: <Intel 82801CA (ICH3)> 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 [EMAIL PROTECTED]:/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 [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
