I recently bought an HP G62 notebook and installed Kubuntu 10.04 on it. I have had some sound problems with it. I upgraded the Alsa driver but am unsure about what I really have. using the command 'dpkg -l' I get Alsa 1.0.22. If I look at /proc/asound/version, it reports Alsa 1.0.23. Which is correct? Thank you to all.
