So you think it is somewhere in esa.c, not in the higher audio driver
(audio.c) or in the ac97 code?

I will need some guidance to help wade through it all, but am willing
to help.  Can you give any suggestions about where to look or how to
go about narrowing down the problem.

Can anyone verify that full duplex works with all the other audio
drivers, especially including other ones that rely on the ac97 code?

Thanks for the help.

Cheers,
