Things have been going very well and I haven't had anything to complain about.
Slackware has had a lot of upgrades lately. One of the recent upgrades was the ALSA library and utilities. I am extremely happy.
At work, I use a Dell Optiplex 745. This is a slim device with no room for add-on cards, so I use the default soundcard on the motherboard. Until the upgrade, this has been a source of great annoyance for me. The card allows one connection or one user. If I am using XMMS to play music, then it's got the soundcard locked. If I accidentally browse to YouTube from Reddit, or to any page that wants to play sound, then Firefox plays no sound and will shortly lock up and I have to drop to command line and kill the various firefox processes. This has been very annoying.
Then this week, I did another Slackware upgrade and noticed that the ALSA library and utilities had been upgraded. Shortly after, I was playing music and then clicked through to YouTube and was shocked that I could hear the YouTube video AND could still hear my music. Something changed for the better. Life is good.
