I have installed ubuntu 9.04 on lenovo y530. It has 4.1 speakers and an internal microphone. I would like to set it up so that all four speakers work and either the internal or an external microphone works...on skype.

Currently, I have made no changes to audio configuration except installing pulse - padevchooser, paman, pavucontrol.

Following is the audio controller: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)

Please tell me:
1) what information do you need to help me
2) What to install / uninstall
3) how to set it up

---I tried to figure this out myself by reading Y510 thread, but I can't understand what to do.

Thank you for your generous support!
