[Alsa-user] cs46xx rear channel in kernel 2.6.11

[Ron M. <rj...@rj...>]

I've been using the rear channel of my Turtle Beach Santa Cruz card
(which uses the cs46xx driver) to drive an external stereo amplifier
for several years now, with no problems. However, it seems to be
broken in kernel 2.6.11: there's little or no output from the right
channel. Left channel works fine, and going back to a 2.6.10 kernel
gets me both channels working again.

I'm not sure if this is a known problem or not (I can't find any
recent archives of this mailing list), but has anything changed in the
cs46xx code between 2.6.10 and 2.6.11? 

I can see this in the changelog:

>    A new mixer control 'Duplicate Front' is added for the board with
>    a single codec.  This toggles the duplication of front signal to
>    the rear speakers.

   which may have something to do with it, but I don't see any such
control in alsamixer. The system runs Debian sarge, and here's the
current software versions:

>  alsa-base      1.0.8-7
>  alsa-source    1.0.8-7
>  alsa-utils     1.0.8-4

Thanks,

 .....Ron
