Update on sound and power saving

In an earlier post I wrote about the problems I had with sound in Ubuntu on my laptop. Well, "Henning" commented on it and suggested installing latest development snapshot of Alsa drivers, which I did. I then modified the option line I had added earlier to /etc/modprobe.d/alsa-base to "options snd-hda-intel model=acer". Now jack sensing and recording via the microphone jack work fine! No luck with the internal microphone, though. I'm not sure if I haven't just found the right settings or if it's not supported yet.

Henning also suggested this nice website lesswatts.org and the program powertop, which I promptly installed from Synaptic. I'll have a closer look at it when I get the time.

PS. I would like to thank those who have commented on my earlier post. If you have anything to add I hope I hear from you. Especially if you have any suggestions on how to get suspend to work.

Update 2008-04-26: ChrisSavery wrote a couple of interesting comments to this post about the built-in mic. I was unable to get it working, but perhaps someone else can give further advice?
