Bug Description
This bug seems different from the other Intel HDA bugs I can see; the sound is working but the volume is very low; to the point where to get it to about the right level output I have to turn up the amp and the analogue control on the laptop and the mixer to full and then it is just OK.
Note:
The sound worked on Feisty.
This is on a Toshiba Equium A100 laptop,
This is the behaviour after a reboot, after a resume I suffer #134167 (no sound at all)
Feel free to ask for any other machine details;

Hi Dave.
i presume you're using gutsy with all packages up to date, is that correct?, if no could you please provide the version of the software you're running.
if you execute the following command does make any difference:
user@machine:~$ amixer -c 0 sset "Master",0 100%
i ask you because i just see the PCM volume level.
