I always see that legacy thing too when I run AlsaConf, so I don't think it's something you need to worry about. But have you had a look at the article in the SL Wiki: HOWTO: Resolve Problems with HDA-Intel Sound Cards
EDIT: From your screen snapshot it looks like you have the same audio controller as mine, so you should be able to get it working:
- Code: Select all
# lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
I didn't have to do anything apart from the usual AlsaConf/AlsaMixer stuff, but perhaps working through the SL Wiki article will help you get yours working.
