UPDATE 12/2/09 - Reprieve earned, I decided to try some quick trouble shooting on my son's computer. I used the Pulseaudio configuration tool to select the SoundBlaster on my computer and sound now works. Actually sound works better now that my card is properly selected than it has on any of the recent releases of Ubuntu that I have tried. I still feel that the installer needs to do a better job at properly identifying sound cards and selecting the correct card. Especially when your audio and video section of your support forum is loaded with unanswered inquiries as to how to fix sound.
UPDATE 11/09/09 - Hey look the exact same reaction from another person that just wishes Ubuntu would stop breaking sound and blaming the user.
I have gone on record in the past criticizing and praising releases of Ubuntu Linux. The Ubuntu Server edition has worked flawlessly for me for a number of years and I still use it to host my websites. I have administered Red Hat and SUSE flavors from a Server perspective and I find Ubuntu's Server to be right up there with those other enterprise flavors. It is with the desktop and Ubuntu that I have had a love hate relationship. The latest release is no different and it is totally because of the same issues I have been fighting with for the last year and a half. I had swore to a friend of mine that after I got the last version working that I would not upgrade ever again on that computer. The technology geek in me could not resist though, so I clicked the button to upgrade Ubuntu 9.04 to Ubuntu 9.10 and as expected I am sorry I did it.
Over the last year and a half every upgrade of Ubuntu meant that I spent a week trying to get sound to work. In the more distant past I had issues with wide screen resolutions, but I have not had those types of issues in over 2 years. But sound has been a thorn in my side for over a year on all my Dell desktops and I swore after getting sound working on Ubuntu 9.04 that I would never upgrade the computer again. Well, obviously I did and again the sound is gone on the computer, everything else works flawlessly. I am usually fine with trouble shooting these matters but the sound settings look to have changed a whole lot from the last version and some of the quick fixes I tried did not work at all. I think I am officially done with Linux on the desktop until I have a newer computer to put it on, and that is no guarantee sound will work. The same old replies in the support forums show up every time this occurs, either your hardware is too old or too new and you have to perform step 1 through 15 which may or may not work (usually does not work). I heard the same exact thing when I had issues with Windows 7 and I am sorry but a computer from 2005-2006 is not obsolete and Dell is one of the most widely used brands all telling me that it should be among the first to have supported hardware.
The computer I was running Ubuntu desktop on is the computer in my son's bedroom and the web browser with Flash is just about the most important application needed on that computer. Flash of course works, just no sound, which is sort of the same as Flash not working. It is just not Flash that has no sound, the computer plays no sound period. My son is now running OpenSolaris, and trust me OpenSolaris has it's problems as well, but once something is working or hardware is supported, that support is not removed the way it is with Linux. I have upgraded to the latest builds of OpenSolaris almost as soon as they were released over the last six months and so far have not been left with a non-working desktop even once.
About six or seven months back I tested a list of five or six different Linux distributions and every one of them left me with a desktop with no sound. I have had it, at least for now. Perhaps when the time comes where I replace a desktop and I do not do so with a Mac I will buy a machine with Linux installed. I hesitate to even try to build a desktop from this juncture because I cannot say with confidence from my experience I would know which sound cards are fully supported by Linux. I keep hearing that Pulseaudio is not the problem, well what is? I see the long list of people saying they have no sound with every release but there seems to be no fix, just a recurring problem. I understand getting an operating system to work on the variety of hardware that Linux does can be a challenge, I suppose I have grown tired of trouble shooting the no sound issue and quite frankly I have never been clear on what I did to fix sound on the prior releases. In most cases after trying a whole slew of different suggestions and rebooting 10 times it would suddenly just work. That never gave me a warm fuzzy feeling. As of now this is a OpenSolaris and Mac OS X household, I hope to welcome you back someday Linux.
