It is a new driver for the Renesas SH7343 Sound Interface Unit that I 
wrote. The product is a new cell phone with a LCD display that will play 
movie clips and audio to headphones. It worked well on my test board 
when I was using manually compiled alsa-lib and alsa-utils. Now I'm 
testing the software image that will be release to the customer and I 
get this errors. This image includes alsa libraries that were built by a 
different process (not sure about the differences though). Since the 
driver worked before, I think it might be a configuration problem... but 
I can't say for sure.

Thanks,
