hello, everyone. I'm facing some problem about sgtl5000. I have a board based on imx6q, and use sgtl5000 instead of wm8962. I have add the driver for sgtl5000. When booting, I can see it has been recognised correctly, but there is no sound at all. Could anyone give me some ideas?
part of the log is following:
sgtl5000 1-000a: sgtl5000 revision 17
mmcblk0boot1: unknown partition table
print_constraints: 1-000a: 850 <--> 1600 mV at 1200 mV normal
mmcblk0boot0: unknown partition table
asoc: sgtl5000 <-> imx-ssi.1 mapping ok
hub 2-1:1.0: USB hub found
imx_3stack asoc driver
hub 2-1:1.0: 4 ports detected
Initialize HDMI-audio failed. Load HDMI-video first!
ALSA device list:
#0: sgtl5000-audio
Bead regards,

Hi zhang
since there is no output, may be recommended to check signals with
oscilloscope.
Sgtl5000 is used on i.MX6 boundary devices boards (not used on nxp reference
boards) and usage is summarized on

Hi,
Please specify:
- Linux kernel version (3.10.x or 3.14.x etc)
- OS (Android, Linux Yocto/Ubuntu/Buildroot)
If you have amixer available you can try to turn all the volumes up.
Regards,
Gary
