Hi Anand,

Here are the two parts of the SGTL5000 audio driver (codec + i.MX specific):

linux-imx6/sgtl5000.c at boundary-imx_4.1.15_1.0.0_ga · boundarydevices/linux-imx6 · GitHub

linux-imx6/imx-sgtl5000.c at boundary-imx_4.1.15_1.0.0_ga · boundarydevices/linux-imx6 · GitHub

Hope this helps.

Regards,

Gary

Dear Gary Bisson,

I have used your drivers for SGTL5000 and added into my software package. The device probing is successful and shows up the alsa device list.

When I run the 1kHz sine wave .wav file using aplay command, I am observing the signals on LINE OUT_L only and no signals at LINE OUT_R. Also the signal at LINE OUT_L is not as expected (>>>1Khz its varying frequency and doesn't look like sine wave)

Could you please let me if any other commands to be executed before running the aplay command.

For any clarification feel free to ask me. Thanks for the support

Thanks
