[alsa-devel] sound on smdk2410
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.

Hi Liam, the messages printed on the output are all the same (asoc:machine hw_params failed). It is printed tens of times... I couldn't play a .wav either.
I am using gcc 4.1.2, so it is not 3.
I will check 1 and 2 but I need some hints on where in the code this is set.
Thanks, Henrique

Hi, -EINVAL for rate/channels can be returned in the hw_params path in the drivers. So smdk2440.c uda1341.c or s3c24xx-i2s.c if any of them decide the parameters are not valid.
Did you use aplay to play the .wav, can you tray aplay -f cd blah.wav
This selects 16bit, 2 channels, 441000 and from the looks of the drivers should work fine.
