dell latitude 2110: speakers work; headphones don't work

[Mark Summerfield]

I checked System|Preferences|Sound and nothing's muted. I've attached lspci output in case that's helpful.

I read the HdaIntelSoundHowto & added a line at the end of /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel ????

where for ???? I tried every Dell-specific option listed, but none solved the problem.

I ran the alsa-info.sh script and have attached the results in the hope that they may prove helpful.

Do you think it could be due to the problem described here (and for which there appears to be a fix?):

Note that this bug no longer affects me since I am returning the 2110 to Dell. Not only don't the headphones work, but when I type in text, at random intervals the text cursor jumps and inserts semi-random text, so the machine isn't even good enough for taking notes.

Backstory: I ordered the machine with Ubuntu 9.10 preinstalled but it was delivered with no OS at all. I contacted Dell and they just said they didn't supply Ubuntu any more---but they hadn't told me that between the time I ordered the machine and when it was delivered so I had no chance to cancel it. So in the end I installed Ubuntu myself (10.04), and hit the problems mentioned above. When I requested a return for full refund Dell didn't acknowledge, so just over a week later I filled in the request for return and refund again: this time Dell replied straight away saying that more than 7 days had passed so I couldn't get a refund! Fortunately for me Dell broke the Misprepresentation Act since what they supplied wasn't what they advertised and what I ordered. However, it has cost me hours of wasted time trying to get the machine to work, and now recorded delivery letters to get them to refund me. Clearly I will never buy anything from Dell again and will always recommend that people avoid them like the plague.

I am also affected by this bug. I'm also using a Dell Latitude 21110 with Lucid and I'm having the described problems.

Are there any additional information that I can provide to help the investigation and fixing?

I think this may have something to do with the upgrade to 10.04. I completely reinstalled the OS after I received mine, the sound worked fine in 9.10, but not in 10.04 reinstall. What I do remember is that the 9.10 had two hardware drivers installed under the "hardware drivers" in the "system" menu. On reinstall I found the driver for the Broadcom Wireless, but the other I did not jot down and I can't remember the specific name, put it was a PCI express driver of some sort (for the SD-drive?).
