I don't know about any of you, but I love the new features of 9.10. There are a few pet peeves, like a super communication notifier that doesn't do anything at all (just sits there like a bump on a log, never notices mail, IMs, anything on my system - it's happened on other people's systems right out of the box, and they have it marked as a low priority, c'mon devs...if the thing doesn't work at all, that's not a low priority.)
Anyhow, I digress...the REAL ISSUE I have with our sweet cuddly Koala is he's using Pulse still. Bad Koala! Put down the inferior sound server!
Just a suggestion to those who hate Pulse as much as I do (which would only be a scarce few in this world, I'm sure...) they have made it amazingly easy to take care of.
First, simply go into Synaptic Package Manager (System - Administration - Synaptic Package Manager for those of you who are new) and do a search for pulseaudio. From this search, find PulseAudio and PulseAudio-utils and mark both for removal (don't panic when it tells you it's going to remove the desktop, it won't remove "the desktop").
After this, search for ALSA and install alsa-oss and (I personally do this even though it's not needed) alsa-tools.
You're now running a system without cracks, pops, hisses, lagging sound, lockups, audio mysteriously dropping out from one program but not another, etc etc etc.
With this setup I can run a game under wine (winecfg audio set for ALSA) listen to music on rhythmbox and still hear bloops from my instant messenger (Pidgin of course, who'd want to use Empathy until they add a feature to NOT LOG EVERY CONVERSATION YOU HAVE...silly devs)
This post has been part rant, part rave and part advice. If the rant offended you, I apologize. It's just my opinion. If the rave excited you, it should! Aside from a few issues, Karmic Koala is a beautiful build. If the advice helped - awesome. Glad to be of service.
For flames or anything else, I direct you to the "Reply" button...go ahead, you know you want to...it'll make you feel better in the end...you can go off and tell me how awesome Pulse is.
