Oh thanks. This page provides more accurate information. It makes
sense.

Me too. The alsa cs4236 driver also handles smoothtly this CS4239
chipset. Except for the sequencer/midi abilities (see my previous
mail to the list). So I thought the driver for the CS4610 driver 
could give me better results. But this one  (both in the official
kernel, and in the alsa sources) expects the presence of an AC97 
chip, which cannot be probed in the 770Z. Probably because it doesn't
exist as suggested by Jaroslav Kysela, the alsa guru.
