Hi there,

i am using audio codec (TLV320AIC3106). in my board. i have configured all the drivers and  sound card support needed for my board and built them as a module.. it is getting compiled successfully as all needed .o are present there.. but when i connect headphones to 3.5 mm jack (configured with codec) for listening something,nothing comes.

In every first attempt of boot ,i just get some noise for fraction of second ..after that nothing come at all.... here are the logs which come when i play .wav file .....

root## aplay -t wav /demo.wav

[  111.900390] omap-dma-engine 4a056000.dma-controller: allocating channel for 79

Playing WAVE '/lion.wav' : Signed 16 bit Little Endian, Rate 11025 Hz, Stereo

[  113.165069] omap-dma-engine 4a056000.dma-controller: freeing channel for 79


any help for further processing in it should be highly appreciated.... thanks in advance ... :)

    Hi, Dusty,

    Sorry you are having difficulties getting this to work.

    Unfortunately, in this forum, we are pretty much dedicated to questions on the codec itself. It sounds like your issue is with the drivers, and we can't help you with that.

    I have seen a few other posts (maybe in the OMAP e2e) about similar topics, maybe one of those threads can help you, or maybe someone from the community with experience on this combination will chime in.
