Hi all,
I'm testing sgtl5000 on sabresd. The playback feature has been tested by using aplay **.wav and is proved OK.
But the recording feature test failed.Below is the progress:
arecord -l

Recording WAVE 'record.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
aplay -Dplughw:0,0 record.wav
Playing WAVE 'record.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
I can't see any error message, but I can't hear any sound.Why?
Any advice will be appreciated!
Best Regards

Hello Xiaoquiang,
What version of BSP are you using?, I am testing with the Freescale Demo Image from the Freescale Web site that it is already pre-build, and the use a mic, to the Line1 and it is working fine, have you try to use the record wave in a windows host to see if the audio record, it is not wrong. Or do you make any changes to the BSP related to the SGTL5000.
Have a nice day sir!
Dear jamesbone,
My BSP is L3.0.35_4.1.0, I have played the wave file in windows but no sounds heared. The only change I have made is changing i2c
bus number of sgtl5000 in imx-sgtl5000.c,that is from "sgtl5000.1-000a" to sgtl5000.0-000a, because my codec is on bus0.
