can not record with sgtl5000

[xiaoqiangyang]

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

• List of CAPTURE Hardware Devices ****

card 0: sgtl5000audio , device 0: HiFi sgtl5000-0 []

Subdevices: 1/1

Subdevice #0: subdevice #0

aplay -l

• List of PLAYBACK Hardware Devices ****

card 0: sgtl5000audio , device 0: HiFi sgtl5000-0 []

Subdevices: 1/1

Subdevice #0: subdevice #0

arecord -Dplughw:0,0 -r 48000 -f S16_LE -c 2 -d 5 record.wav

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

Xiaoqiang

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.
