Hi Eric, I am using the same Devices i.mx27 ssi as a slave and tlv320aic33 as a master. I am getting the bit clock and word clock but I am not getting the data when I play using aplay command and it is giving the underrun error. I am using the linux-2.6.32 kernel I am giving here the register dump. mx27# aplay test_file.wav dump @ imx_ssi_startup STX0 0 STX1 0 scr 0 sisr 3003 stcr 200 srcr 200 stccr 40000 srccr 40000 sfcsr 440044 stmsk 0 srmsk 0 sier 3003 Playing WAVE 'test_file.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo dump @ imx_ssi_prepare STX0 0 STX1 0 scr 50 sisr 3003 stcr 289 srcr 289 stccr 4e000 srccr 4e000 sfcsr 440044 stmsk 0 srmsk 0 sier 783503 dump @ dma_new_period STX0 0 STX1 0 scr 50 sisr 3003 stcr 289 srcr 289 stccr 4e000 srccr 4e000 sfcsr 440044 stmsk 0 srmsk 0 sier 783503 dump @ dma_new_period STX0 0 STX1 0 scr 50 sisr 3003 stcr 289 srcr 289 stccr 4e000 srccr 4e000 sfcsr 440044 stmsk 0 srmsk 0 sier 783503 dump @ imx_ssi_trigger STX0 0 STX1 0 scr 53 sisr 3001 stcr 289 srcr 289 stccr 4e000 srccr 4e000 sfcsr 440044 stmsk 0 srmsk 0 sier 783503 dump @ audio_dma_irq STX0 0 STX1 0 scr 53 sisr 3001 stcr 289 srcr 289 stccr 4e000 srccr 4e000 sfcsr 440044 stmsk 0 srmsk 0 sier 783503 dump @ imx_ssi_trigger STX0 0 STX1 0 scr 51 sisr 3001 stcr 289 srcr 289 stccr 4e000 srccr 4e000 sfcsr 440044 stmsk 0 srmsk 0 sier 783503 underrun!!!
