[LAU] Question on multichannel audio on Inspiron 1525 [Ubuntu 8.10]

Hi, I know this is quite a longshot as it is so specific to Ubuntu 8.10 on a Dell Inspiron 1525 and the (few?) people using it..! Anyway, here goes... I would like to use the two headphone jacks + the mic jack as outputs to create a 6 channel output (3 x stereo). So in qjackctl or patchage I guess I will need to patch it like this: audio out_1 & out_2 to system playback_1 & playback_2 (going to 1st headphone jack); audio out_3 & out_4 to system playback_3 & playback_4 (going to 2nd headphone jack); audio out_5 & out_6 to system playback_5 & playback_6 (going to mic jack). My problem is that I am already a few too many steps ahead of myself! To start off with I can't even get the 2nd headphone jack working, let alone set the mic up to send a signal. I've looked at the help "Second Headphone Jack Does Not Work" but it concerns 7.10 and is not relevant to me: http://linux.dell.com/wiki/index.php..._Does_Not_Work <http://linux.dell.com/wiki/index.php/Ubuntu_7.10/Issues/Second_Headphone_Jack_Does_Not_Work> Can anyone help me at least get started with setting the 2nd headphone jack up and getting independent audio to it? At least then I'll have 4 outs to start with... Thanks a lot, Peter
