TrixBox Vitualization on VirtualBox, Timing issues

Hi there

I recently installed TrixBox on a virtualbox virtual machine.
As one might expect, i got hit by timing issues: choppy sound, clock synchronization problems, etc...

I got a few clues by installing the guest additions for VirtualBox
Basically, what this does is that it tells the guest system "you've been fooled, you're not running on real hardware but in a virtual environment" and to cope with some shortcomings, one of the beeing that the virtualized hardware clock may not be running too well.
But with no success, still ugly choppy sound. However: it makes sense to install the guest additions.

What solved my problem was the following:
There seem to be problems with ACPI in virtual machines in the linux kernel used in TrixBox 2.8.
So the workaround I used was simply to disable ACPI (yeah... it's not REALLY a solution, but it's an acceptable workaround for me)
So, I went into the Virtualbox manager, selected the "settings" of my TrixBox, and under "system" Ie unchek the box "enable ACPI". Awaywent my choppy sound problems... The system's been running fine for two weeks now.

Hope it lasts!

Good luck to you!

choppy sound fixed

Opposite results...but wanted to post for someone else, nevertheless.

I just installed 2.6 on virtualbox. Choppy sound, etc... I found this post and went into system settings and found that my ACPI was NOT checked.

I was able to correct my choppy sound by going into the system settings | Acceleration tab | and unchecking hardware virtualization(enable vt-x/amd-v & enable nested paging).

Started the box back up and as far as i can tell, running as good as in a physical environment. I'm going to stress test over the weekend.

Thanks for the info

Thanks for the info Matt.

I'm actually having problems again on that system, so I'll check out your settings.
Keep us posted with your stress test results.
