[mythtv-users] Re: OSS (i810_audio) Driver Duplex Issue (asus pundit)

[Reza Naima]

I did a diff of the rh drivers and the 2.6.0 and the changes seemed
mostly geared at interfacing with the newer version of the kernel rather
than adding support.  The below lines appear also in the 2.6.0 version.

Oddly enough, after enough fiddling, I found out that by removing and
reinstalling the oss module manually, somehow it would support full
duplex.  I imagine it has to do with the order in which the modules are
installed, but I havn't mastered that yet. 

It still complains about not having full duplex, but it works..
