Hello. I am running Ubuntu 11.04, and XP as a guest system.
However, I am experiencing sometimes quite-significant audio delays, and was wondering if I was the only one to which those kinds of things were happening.

Alternatively: does the audio work synced for anyone? Or is it the same problem for everyone?

Bump.
May the problem be because I am selecting a Intel AC'97 controller on the guest machine, however having disabled that very controller from the motherboard of the host system through the BIOS?

Re: Audio delays, sound lag, and sync problems
no, the emulated AC97 is not related to real hardware, its connected to the host audio driver you select in the guest settings: alsa, pulseaudio, oss or null. I'm using alsa on my Debian boxes and don't have any sensible lag, OTOH i don't do sound editing and the like in my guests.twipley wrote:May the problem be because I am selecting a Intel AC'97 controller on the guest machine, however having disabled that very controller from the motherboard of the host system through the BIOS?

Re: Audio delays, sound lag, and sync problems
thanks for the idea, fixedwheel.
i have just (seemingly) solved all the audio-sync problems i had through switching over to alsa in the guest-machine settings.

so (as always) pulseaudio was to blame ...twipley wrote:solved all the audio-sync problems i had through switching over to alsa
