Ubuntu Jaunty with ATI Azailia (Intel HDA) Audio

This is a somewhat obscure post, but it’s for my future reference and anybody else that had audio problems after upgrading to Ubuntu Jaunty.Firstly, let me say that my audio worked fine “out of the box” with Ubunto 8.10 (Intrepid). I have an AMD mobo with an onboard sound card built by AMD/ATI (or Intel), I’m not sure which. Here are some descriptions for my sound card I saw in various hardware lists in my system:
ATI Technologies Inc SBx00 Azalia (Intel HDA)
RS780 Azalia Controller
ALC1200 Analog
snd-hda-intel (the driver)
To make a long story short, I ended up following this excellent Ubuntu sound troubleshooting guide in the Ubuntu Help section. The part that seemed to do the trick was when I “purged” all of my audio config/setup and set it back to “factory defaults”. This was accomplished with a single (long) command in the terminal. After that, I was able to hear sounds in the “Sound” panel under System->Preferences. However, I had to try all of the different devices under the dropdown before I found one that worked. In my case it was “HDA ATI SB ALC1200 Analog (OSS)”. I’m not sure I like that I had to settle with the Analog device instead of digital, but oh well. At least I finally have sound working again. On second thought, I’ve heard that Analog is better than Digital when it comes to music (sound waves are analog not digital). So I guess I’ll survive. 🙂
