http://askubuntu.com – Sound isn't working at all, except when I connect my headset. I think it's hardware problem? What can I do to fix it? I have a ThinkPad with HDA Intel PCH. I even tried filling a bug report, but now I think I shouldn't have as it majorly seems to be a hardware support problem. Also, a guy posted something on the bug report that I can't make sense of (Feeling so ~n00b right now [._.] ). I think I am supposed to patch something, not really sure :( Thanks. (HowTos)
