Ian you own this? There are ommissions Ive found when you updated this to include Precise.
Sure I'll give you the answer. But yu have to go thrugh my rant to get it.
First do not expect me to be tactful. In my line of work PC and tact servce only to get people hurt or worse. I said Zero BS. You ask me a question you get an answer that helps. Since Linuc and especially Ubuntu came to the internet the watch word is have a bucketful of BS. So ask, I'll tell it like it is or I won't answer. While Andy may have tried to be heplpful he should not have answerd at all.
I've asked Q's on all kinds of Lunx forums all over. I find I get BS by the ton, Almost never get an answer. Thay are either l33t sp4k snobs keepping what they think is a trade secret or they are just tossing out a line of BS to make it seem like they know something while knowing nothing and not answering the question.
So here's the analysis and the solution.
The problem is static noise on an SB Audigy 2ZS card. Fist attempt to solve it was to remove it and use the onboard sound card. Didn't work. ALSA (you do know what ALSA is right?) doesn't directly support the AC-97 bridge on an Msi 848P Mobo. A driver specific to the chip set is needed and there isn't one in the ALSA lib.
Static on Creative Slabs boards in not a new issue. It is thought to be either a buss mastering problem on the video bus, the AGP DRAM timing is off or Creative still uses cheap capicators that leak after a few years creating the static noise.
AFAIK the only way to get the drivers you need is to compile your own kernel, something I know nothing about.
You could look at a minimum install image and instal whatever packages you need, not an easy task.
The solution: Dump the Creative Slabs and drop in a Sabrent sound card. $12.00US at Fry's
In general not necessary since with the introductioon of Precise Pangolin 12.04 LTS now spports full UPnP. Pnp sucked in Natty. You may need to DL specific drivers for yor video card but so far not. More on that when I put the second monitor on.
Now questions for you guys please.
Define what a server is to you. Servers do not have to run headless, I've used headed servers for years to run windfarms with the server eunning enough of a dos shell to kep diags on the windturbines. The object of a server is to serve. A modern media server not only includes compjuters scatterd around the netwrok but the main media room as well with a direct hardwired video and audio. It's no additional load on the server and extends the definition of server.
