Hi Nishanth,
Hope you are doing well.
We have an issue with the Linux kernel 2.6 for OMAP 2430
which is available on TI site for download. The Stereo effect
does not work. Would you advise us some thing, why it does
work? We are planning to test our surround and other effect modules
on this target but due to stereo does not work, we can't test our midi
engine with effect module.
Please advise us if any to come out of this problem.
Best Regards
chandrashekhar

Chandrashekar,
If ur using MV kernel, then there are some interesting things u can play
with :).. u can now choose to switch b/w the onboard speakers and the
headset speakers using IOCTLs (don't remember offhand what it was).
There is one interesting factor I had reported to the SDP team,
recording can be done from headset mic (the 2.5 mm) only if I plug in a
headset into the 3.5mm jack.. just thought I'd warn u on this.. minor
irritant, but better know than being surprised..
Regards,
Nishanth Menon

Hi Chandra shekhar,
Which version of 2430 SDP is this and are you working with TWL4030
(T2)
audio codec?
There was a noise issue with T2 audio codec and got resolved later.
This
needs some hardware modifications. You might have
to upgrade your
board.
