No soundcards found & Adobe flash

[CaptSkip]

Just installed Jaunty 9.04 and cannot play any cd's or music files, view or hear youtube.
I tried to download adobe flash but the file just sits on the desktop, cannot open.
results:
bryan@bryan-desktop:~$ aplay -l
aplay: device_list:217: no soundcards found...
bryan@bryan-desktop:~$

I kept my notes from my install on 8.04 but I am still Lost.

lspci -v search for multimedia audio controler and look for field : kernel driver in use
if there is nothing some how ubuntu did not recognize your sound card which is rare
there is a couple a thinks you can do :
1.you can install hwinfo apt-get install hwinfo and then type in shell hwinfo --sound you will see a couple a fields you need to look only to Model :
which represent your sound card
2.type dmesg | less and search for ALSA device list
3.you can install module assistant and after you have model of your card type module-assistant form graphical menu choose SELECT and search for appropriate driver or choose alsa
4.or you can download the new kernel and boot

there is other ways but more tech savvy
You need to be root for all that

If somethink is not clear write
