[alsa-devel] Error with "Unsigned 8 bit, Rate 8000 Hz, Mono" track

10 Aug 2012


      Hi,
Running 3.6-rc1 on a mx28evk I get the following error with this wav format:
root@freescale /home$ aplay k3b_error1.wav
Playing WAVE 'k3b_error1.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
[  303.640000] asoc: machine hw_params failed: -22

Haven't started debugging yet, but if anyone sees something obvious,
please let me know.
This same file plays correctly on mx31/mx27/mx51/mx6q boards.
