i.mx6q sabreauto board i replaced the original audio codec cs42888 with rt3261. now play is ok , record sometimes is ok , sometimes you can only hear noise.
I linked codec ADCDAT1 to DACDAT1 and there is no noise speak out when recording . I am sure there is something wrong in data transfer in i.mx6q when record but i don't how to fix it.
Could anyone help me
I linked codec rt3261 to im6q SSI interface instead of ESAI interface
and It works well
Hi zj,
I can't confirm if your connections of I2S signals on schematic is correct, so could you give a scrrenshot of your schematic or share your schematic ? if you don't want to share it with me, you can refter to our another solution for i.MX6Q which is name MCIMX6 SabreSDP , you can find it's schematic on web link : http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&fpsp=1&tab=Design_Tools_Tab
then compare your I2S connections with that of Sabre SDP design, check if they are correct .

i.MX 6Quad Sabre-AI this is the schematic i'm using CPU_DAI is ESAI and original codec is CS42888
I replaced CS42888 with rt3261.
is there something wrong ?
Thks for your reply
imx6q ESAI audio interface <---> rt3261
I linked rt3261 ADCDAT1 to DACDAT1 and no noise spk out when recording
so I think there is something wrong in imx6q receiveing data from codec rt3261 ADCDAT1
