Unfortunately, I get this error when I try to run < speaker-test >: # speaker-test speaker-test 1.0.28 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 128 to 32768 Period size range from 64 to 16384 Using max buffer size 32768 Periods = 4 was set period_size = 8192 was set buffer_size = 32768 0 - Front Left Write error: -5,Input/output error xrun_recovery failed: -5,Input/output error Transfer failed: Input/output error The codec is connected to SSI2 pins and I would like to use the SSI0 internal port in asynchronous mode (4 wires). The command interface is I2C1. The codec seems to work because it generates both bit and frame clocks (the codec is the master) but no data are coming from the processor. I'm using kernel 4.1.7 but I have got the same error with versions 3.19.8, 4.0.5 and 4.0.9. I have also tried the < imx-sgtl5000 > driver and I get the same error. I can use < alsamixer > with no issue.
