iMac 20" Headphones sound very low in 8.10 Intrepid

[lucian_sh]

It's been a while since this problems is around, without a very specific solution, I have a 20" mid 2007 aluminum iMac and I'm running Ubuntu 8.10 Intrepid beta, just updated from 8.04 and everything works fine but the audio, the headphones volume is very very low, I tried all the tricks around, all the mixers are at max, everything unmuted, and checked with various apps. I currently I have installed alsa-driver 1.0.17 the official Ubuntu package and it seems that the bugfix that appeared like a year a go is not fully implemented here.

I'm also posting the output of some diagnostic tools:

- lspci -vvnn
- cat /proc/asound/version
- cat /proc/asound/card0/codec#0
- amixer

So any ideas in how to fix this bug will be appreciated.

Please create a bug report for this. Kernel Freeze for Intrepid is just around the corner, and this would be an important fix to get into the kernel for 8.10.

It should be marked against 'linux' and 'mactel-support'

By the way I'm quite new in launchpad, and didn't found out exactly how to mark the bug... :) How do I do that?
