Sound card problems

[Vladimir Kosovac]

I'd appreciate if somebody can help with this.

Computer is Dell Latitude CPx H, RHEL 3, 2.4.21-9.0.1.EL kernel. It was
running various releases of Red Hat since 6.2, SuSE 8.1, Fedora Core 1,
FC2 test1. None of the kernels prior to EL one (above and 2.4.21-4.EL)
had any trouble with the sound - thinking about it, all beta releases as
far as I can remember worked well, too.

redhat-config-soundcard detects sound device as ES1978 Maestro 2E but it
is not able to load maestro3 module due to 'unresolved symbols in ac97
and ac97_codec'.

Am I missing something obvious or perhaps it's a bug?

Messages in syslog are:
