No more audio after upgrading the packages on RNH

[Nicolas.Castagne at imag.fr]

Hi all,

I installed recently various machines with red hat enterprise 3.
I then upgraded all the packages by using upd2date in red hat network.

Since then, the audio facilities are out of order (they were OK before).

The redhat-config-soundcard tool runs correctly, still displays the audio
driver info, but the 'test sound' button no more plays anything.

The various Volume Control tools do not run, nore the audio players.

Executing more /var/log/messages results in

The machines are DELL precision 360, with Analog Device internal
AD1980-AC97 sound cards.
I tried to reinstall drivers provided by DELL (and even ASUS) for the
card. No success.

What should I do ?

Thx
Nicolas
