Hi, Since installing Fedora Core 1 the sound is garbled/crackling on vmware using guest host Windows XP Professional. Any ideas on what might be causing the problem? Errors that display in /var/log/messages: kernel: i810_audio: DMA overrun on write kernel: i810_audio: CIV 3, LVI 2, hwptr 1b58, count -168 kernel: i810_audio: DMA overrun on write kernel: i810_audio: CIV 2, LVI 1, hwptr 1368, count -8 kernel: i810_audio: DMA overrun on write kernel: i810_audio: CIV 22, LVI 21, hwptr b000, count -148 When it did work, the following was installed: RedHat 8 - kernel version 2.4.18-27.8.0 VMWareWorkstation - 4.0.0-4460 I did a new install (no upgrade) of the OS to Fedora Core 1. I have tried the following combinations of kernel and VMWareWorkstation but continually get crackling sound: Fedora with kernel version 2.4.22-1.2115.npl and VMwareWorkstation-4.0.5-6030 Fedora with kernel verison 2.4.22-1.2174.npl and VMwareWorkstation-4.0.5-6030 Fedora with kernel verison 2.4.22-1.2174.npl and VMwareWorkstation-4.5.1-7568 After running vmware-config.pl, I started vmware and reinstalled VMWare Tools. I did not create a "New virtual machine". I used the one that was already created under RH8. I searched vmware's website but unfortunately they aren't supporting Fedora. I did find some settings for older version of RedHat that I tried in winXPPro.vmx: sound.maxLength = "256" sound.smallBlockSize = "128" sound.highPriority = TRUE lspci output: 00:00.0 Host bridge: Intel Corp. 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 01) 00:01.0 PCI bridge: Intel Corp. 82845G/GL[Brookdale-G]/GE/PE Host-to-AGP Bridge (rev 01) 00:1d.0 USB Controller: Intel Corp. 82801DB (ICH4) USB UHCI #1 (rev 01) 00:1d.1 USB Controller: Intel Corp. 82801DB (ICH4) USB UHCI #2 (rev 01) 00:1d.2 USB Controller: Intel Corp. 82801DB (ICH4) USB UHCI #3 (rev 01) 00:1d.7 USB Controller: Intel Corp. 82801DB (ICH4) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corp. 82801BA/CA/DB/EB/ER Hub interface to PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corp. 82801DB (ICH4) LPC Bridge (rev 01) 00:1f.1 IDE interface: Intel Corp. 82801DB (ICH4) Ultra ATA 100 Storage Controller (rev 01) 00:1f.3 SMBus: Intel Corp. 82801DB/DBM (ICH4) SMBus Controller (rev 01) 00:1f.5 Multimedia audio controller: Intel Corp. 82801DB (ICH4) AC'97 Audio Controller (rev 01) 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV200 QW [Radeon 7500] 02:09.0 VGA compatible controller: nVidia Corporation NV6 [Vanta/Vanta LT] (rev 15) 02:0c.0 Ethernet controller: Intel Corp. 82540EM Gigabit Ethernet Controller (rev 02) Thanks, Vicki
