Hi @spujar
Thanks for your reply.
Yes, the dmesg log was captured with audio card connected.
We modifiled DTSI again, and now signal can be cought on i2c bus 1. The previous error “no acknowledge from address 0x18” has gone, which is comforting.
But the pin7 MCLK still goes flat line on the oscilloscope.
Could you give some advices on how to config MCLK, and how to set frequency.
And dmsg log shows that “Failed to add route x OUT → direct → x Headphone”
[ 4.559915] tegra-asoc: sound: ASoC: no source widget found for x OUT
[ 4.559917] tegra-asoc: sound: ASoC: Failed to add route x OUT -> direct -> x Headphone
[ 4.559936] tegra-asoc: sound: ASoC: no sink widget found for x IN
[ 4.559938] tegra-asoc: sound: ASoC: Failed to add route x Mic -> direct -> x IN
according to this topic, shell has been run, and audio debug log has been upload.
