Hi Kelly.
I did see the Etchnhalf 2.6.24 kernel when looking at synaptic. I only
suggested the musix one, as I have it installed, and know it uses alsa driver
1.0.16. I'm on dialup, and didn't want to download the etchnhalf kernel, only
to find that the alsa driver available on it was earlier than 1.0.16.
Have you got the etchnhalf kernel 2.6.24 x86 installed, and could let me know
which alsa driver version it is using? Otherwise I'll install it myself.
All the best.
Nigel.
