Hi I'm an ALSA SOC newbie. I created a new SOC driver for a new ARM chip but I'm having endian issues at the codec. I started with the pxa soc code since I am failure with the pxa* i2s hardware. The new code is working and data flows fine but due to hardware constraints the bytes arrive at the codec swapped. The codec claims S16_LE. The i2s layer claims S16_LE as does the pcm layer inside soc. The source data in user land is S16_LE. But when the i2s hardware (which I can't change) does dma the bytes go to the codec in reverse order. So, I need a byte swap somewhere. I verified this by sending constant data from user land via the oss compat layer (i.e. /dev/dsp). If I swap them in userland they come out on the scope at the codec in the correct order. Any know the simplest way to do this? I've tried a bunch of ways but nothing seems to work correctly. It seems like ALSA already handles this as long as I tell the right thing from below. -brad _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
