I tried this on linux-samsung tree by applying all the patches from you and Lars.
Can you use -next plus the posted patches please in case there's something been misplaced, it'll help if we're working from the same code base?
Sound tree has some booting issue on smdk5420 so I tried this on linux-samsung tree.
I initialised the dma_data for secondary dai as there is a crash with out that.
Can you please send a patch for that if you find it's needed? Like I said in reply to your earlier mail it looks like this doesn't work anyway so mainline ought to be fixed.
Okay. I will send a patch.
Then I used aplay after running the mixer settings. ./aplay /mars/share/sounds/alsa/Front_Center.wav
So this is 16 bit stereo or something, and did it work beforehand? Like I say I suspect the DMA is ending up being configured with the wrong transfer size, can you check what actually happens there please - what's different about the configuration that the DMA controller gets? I don't have any Exynos systems with mainline audio support so I can't test anything myself.
This stream was working before. dma_size in i2s_hw_params not getting effected as dma_data is getting initialized only at dai probe time. So by default the dma_size is always 4 which is initialized at driver probe time. The fifo_size of dai is also always 0. It is not getting passed from dai driver. I just hard coded the dma_size to 2 and fifo_size to 32 then I can hear the audio only on right ear phone. Still underrun error message appears.
Thanks Padma
