IncrediblePBX 1.8 choppy sound under VMware

[dangtong]

Just got IncrediblePBX 1.8 installed under VM, off my dual core 4gb server mainly for Google Voice dial in and out. That part work fine, but I want to use other feature of IncrediblePBX and the sound is choppy.

I've tried http://pbxinaflash.net/vm/ and couple things mentioned in this thread http://pbxinaflash.com/community/threads/solvedx2-pbxiaf-choppy-sound.66/. And I also have VMware Tool installed, but couldn't have the choppy sound fixed. Those seems to be fixes for PIAF 1.4 that didn't work in IncrediblePBX1.8 Any tip/advice how to fix choppy sound in IncrediblePBX 1.8 installed under VM? Appreciate any help.

Got this note from Richard Tomlinson yesterday. Give it a try and let us know how it goes.

Just a quick note about the latest PIAF running on vmware. Using the current kernel its worth modifying boot.conf to append: divider=10
clocksource=acpi_pm

This has the effect of changing the kernel to 100Hz update which improves audio and drops cpu utilisation. As recommended

Also means that the custom vm kernels as shown on your site shouldnt be needed.

Thanks Ward. Yes, I added divider=10 clocksource=acpi_pm to grub.conf. Still have issue.

Switch to Proxmox. It's free and has never had this problem.

Proxmox looks interesting, but the problem is that I need the vm to run inside my Windows server that I use for media storage, backups, along with the other VMware vm. .

Don't know what to do at this point. Might dig out my old centrino laptop and put PIAF on that laptop. But really hate to run another piece of hardware as I already have too many PCs running 24x7 already.

I use proxmox for:
1. Several Windows 7 KVM's
2. Windows Media Center, feeds Xbox360 extenders in my home. Also acts as a media server and PVR. KVM
3. Production PIAF and a few non production for testing
4. Vicidial auto dialer for some marketing things I do

and just about any other testing I may want to do. I use the KSM kernel for better memory management. It's nice to have everything on one machine.
