I'm now using alsa-driver with my system. I checked the ALSA-Project |
37 |
page and it seems since 1.0.14rcX they have pretty much halted |
38 |
development on the Connexant CX20549 Codec which uses Realtek 282... |
39 |
There is a patch from linuxant.com but it's takes a lot more steps to |
40 |
configure. I'm pretty sure I'll solve the issue by editing my own |
41 |
configuration using theirs as a reference point. I'm probably going to |
42 |
have to downgrade my version of alsa-driver or use the svn sources. |
