Hi, I am trying recent Zoltan Devai's patchs for kernel 2.6.22-rc2 on a smdk2410 board. I reached the point where the kernel recognized the uda1341 sound chip, however, when I try to play something, I get the output below. Can anyone, please, show me the path to follow to get sound working?
Thanks, Henrique

Could you attach all the messages. It's difficult to debug without them.

Can you try playing a wav with aplay and send the results.
Imho, it could be 1 of three things atm.
1. OSS app (and hence OSS emulation) is initially setting hw_params to 8kHz 16 bit mono (this may not be supported by the driver and thus hw_params returns EINVAL). 2. audio rate, channels, format is not supported by driver. 3. ARM gcc < 4.1.1 CSE bug.
