Could you expand on what you mean by "No I/O" here - do you get silent output or does DMA not work either? > set_tdm_slot(cpu_dai, 3, 2), SSCR0_Datasize(16): > Only left channel works. > set_tdm_slot(cpu_dai, 1, 1), SSCR0_Datasize(16) | SSCR0_EDSS: > Both channels work. Just a thought, but you should also be able to get things working by adding a constraint on the format in your machine driver to force use of 32 bit - see things like the WM8903 driver for examples of how to this. Ideally that shouldn't be required, though. > On my board CLK and FRM are driven by the codec, pxa is slave.

BTW, your mail client is doing some really strange indentation here and indenting the first line of each paragraph by a tab which looks like how some other clients do quotation. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
