FWIW Video output seems to be affected as well.Ī Windows XP SP3 guest does not seem to exhibit the same problem. The same problem occurred in V 2.2.4 r47978. Only after the VM is shut down will the problem recur. Having done that, audio playback is restored to normal and will remain normal between reboots of the VM. The problem is temporarily repaired by reinstalling the Guest Additions and rebooting the VM (reboot only, don't shut it down!). Sound distortion such as "chirping" and stuttering may be evident as well. Only after shutting down the VM completely and then restarting will sound playback slow down with a commensurate lowering of pitch as though the clock is running slow. Following initial installation of the guest, sound playback works well. This is an Ubuntu Linux 9.0.4 guest in Virtualbox 3.0.2 r49928 on a Vista SP1 host, a Presario C751 notebook. Couldn't find any similar report in Bugtracker. I hope this is enough information for you guys to help me for now.There's some discussion in community forums related to this, but it doesn't go very far.
#SIGMATEL AUDIO UBUNTU INSTALL#
I attempted to install the latest ALSA drivers but in all honesty I have no idea what I'm doing I've had about a years experience with Ubuntu previously but have never really had problems with hardware until now!
#SIGMATEL AUDIO UBUNTU DRIVER#
I have played around with the volume mixer settings but I think t's down to a driver problem. It may also be worth noting that I get the onboard beep upon error messages also, indicating that no soundcard is installed?

I am using the optical output on the onboard controller to output sound to my AV receiver.Īs I am dual-booting Vista I know that the output works using Sigmatel High Defintion Audio Codec drivers so the hardware is not at fault.
