Hello everyone!! Here's my problem, I just installed Jaunty on my desktop that has a MSI k9vgm-v motherboard and uses ALC833 sound driver. The thing is that I can only use one sound application at the time. I went to system settings > multimedia and saw that have 4 options of sound for each application:
HD VIA VT82xx (ALC883 Analog)
HD VIA VT82xx (ALC883 Digital)
PulseAudio
HD VIA VT82xx, ALC883 Digital (IEC 958 (S/PDIF) Digital Audio Output)

When I test all these options the only one that works is the first one, (Analog) and is the one prefered in all applications. I think my problem might be somewhere around this, can anyone help me to fix it??

This may sound like a silly question, but have up updated/upgraded all of the newest packages?

It's good that you are using Pulse Audio. That is becoming the standard/widely used audio format. If, you want to be bold, look into installing OSS over PulseAudio.

Try going to: system > preferences > sound, and set everything to alsa. Then see if more than one app at a time can use sound.
Also, make sure individual apps are configured to use alsa instead of oss or pulse in their preferences menus. Many people have reported problems with pulse on the ubuntu forums, so try alsa and see if helps.

Thanxs everyone!! I solved my problem setting everything up to PulseAudio
