We are use tc358743 ,the video is ok, But we have met the audio problem.

arecord -r 44100 -f S16_LE -c 2 -d 6 123.wav -D hw:2,0
Recording WAVE '123.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
arecord: pcm_read:2115: read error: Input/output error

we have check the audmux and ssi , but cannot solve this problem..

we are use tc35873_h2c.c as our driver. we have modify the imx_audmux_config to meet our hardware disign.

(we are use

   MX6QDL_PAD_CSI0_DAT7__AUD3_RXD  0x130b0 /*0x130b0*/
    MX6QDL_PAD_CSI0_DAT4__AUD3_TXC  0x130b0 /*0x130b0*/
    MX6QDL_PAD_CSI0_DAT6__AUD3_TXFS  0x130b0 /*0x130b0*/

)

Anyone can help me ?

Hi bill

one can start development using sgtl5000 driver examples, for example for sabrelite board

imx6qdl-sabrelite.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

or tlv320 codec

TLV320AIC3105 on i.MX6Q: no clock on BLCK, WCLK

May be useful first to adjust SSI&AUDMUX settings with baremetal SDK sgtl5000 example

(sdk zip can be found onhttps://community.nxp.com/thread/432859 )

Best regards
igor
