So I slapped Xubuntu on my HP Mini 110 3030NR. Works perfect. I tried a few versions of Mint and had sound issues. Not the case with Xubuntu. Really pleased with it so far and it's pretty snappy after it boots up.
Are you running the latest Xubuntu version? I must admit that I am quite the fan of Xubuntu and it is currently my main distro. I have experienced sound problems in the past when it comes to Mint and I am surprised to see it still happens! I do hate to hear that, but stuff like that happens I guess.
Xubuntu is a very snappy little distribution. The boot up time is not too bad at all and everything works perfectly once it is loaded. This is one thing I have always enjoyed about Linux when compared to something like the laptop I am on that is running Windows 7. Once the laptop boots up, I have to let it sit a bit to "warm up", I guess, or I experience some lagging.
