I.MX28 can not get any audio data from SGTL5000

[英库李]

We are developing a system based on i.MX28, which does audio input and output through the SGTL5000 CODEC.

At begining, everything is OK.

However when it recorded for days, arecord could not get any audio data, so the resulting WAV file is just 44 bytes (file header data only)

The audio input is the same one that lasts 10 seconds. Stopping 20 seconds, the next input comes.

Somedays later,we run into this issue.

Has anyone else seen this issue?

Hi,

Can you share the steps to reproduce the problem as well as the BSP and kernel version you are using?

Is is possible to reproduce the problem with the imx28evk?

Regards,

Alejandro

Hi Alejandro，

We use the L2.6.35_10.12.01_SDK_source.tar.gz for imx287.

And we use alsamixer arecord to record the audio 20 seconds，then stop for 2 seconds.

Days later, the  arecord could not get any audio data.

I think it is possible to reproduce the problem with the imx28evk.
