Comment 1 for bug 59710

Thank you for reporting this bug. However, we still need some more information before we can pass it on to the developpers.
Before you insert the headphone, please execute the command 'lshal -m' in a terminal. This will display all HAL actions. Keep the terminal open and plug now the headphone.
Put the ouput of 'lshal' (another command) in a file.
Now unplug the headphone again and put the output of lshal -m in a file and attach that, with the output of these commands and files:
/var/log/kern.log
cat /proc/asound/cards
uname -r
sudo lspci -vvnn

Thanks in advance
(Please put the results in separate files, it doesn't matter if you have to reply multiple times.)
