Other Parts Discussed in Thread: TLV320DAC3100, AM3352

Hi ,

We are using TLV320DAC3100 with AM3352 sitara processor with 3.14 linux kernel version. Recently we made Audio Codec up with tlv320aic31xx.c(aic3100) codec driver for the DAC3100 -- we done some changes so we got the Audio. But for the very first "APLAY" we are not getting any sound/audio out.

Please any one suggest -- why for very first aplay command is not getting any Audio.

regards,

I suggest you check your DAC register configuration before and after first aplay command.

we cleared all delay bits in the Audio codec registers. Can you specify the any registers which cause/effect the playing Audio.

There are no Codec experts on this forum. You should ask this on the Audio Converters forum: https://e2e.ti.com/support/data_converters/audio_converters/f/64
