So, I just finally installed Ubuntu on my C400 Dell laptop, and I have come accross a particular issue. Hopefully someone with my model laptop, or a DELL with an APR can help me with this issue...

When I try to play music, actually, any and all sounds while docked are played through the laptop speaker rather than piping it through the APR and out the jack.

Anyone know why? I've looked and looked, but no luck.
