Original question:

Audio interfacing with AM5728

How to have stereo sound support?

Other Parts Discussed in Thread: TLV320AIC3262, AM5728

Hi,

I have custom board based on am5728 SOC. It has TLV320AIC3262 audiocodec device connected to it. When we connect headphone to the 3.5 mm jack we get different audio levels on the left and right channels. As suggested by a TI community member we are to copy the first 16 bits of the SOC side buffer DAVINCI_MCASP_RXBUF_REG to its last 16 bits for mcasp3. So basically, to support stereo mode in audio is this sufficient or any other configuration needs to be seen ? Also is it the correct register that is to be modified? If yes, then where do we have to do changes in linux kernel source code directory in order to modify this buffer?

    Hi Vishal,

    This is a duplicate of your earlier question. If the answer you received wasn't satisfactory, can you please elaborate on the details you need after implementing the advice you were given?

    Thank you,

    Actually we needed to modify an SOC register to support stereo mode in headset. For that there  needs to be some changes in Linux kernel as I had asked in my other post. The suggestion that was given on that post was to modify audiocodec registers which is not useful. So could you help in doing changes at linux kernel?

    You need to get the registers for your headphone stereo settings and then get help from the Linux expert in the other thread.

    Unfortunately we are not the Linux expert, he will be able to guide you once you gave him your registers.

    I will close this thread and please use the other thread.
