Can't record audio from i2s

[alexparser]

Hi, I can't record audio from I2S interface on Lime2 (A20) Ubuntu_trusty_3.4.112.

For record the sample 60 sec. (44.1K 16bit) I used this command: arecord -D hw:1,0 -t wav -c 2 -f S16_LE -r 44100 -d 60 test.wav

File is success created and recorded, but absolutely nothing sounds.

Why I can't write sound?

Check your sound mixer settings, make sure if all channels aren't shut, Did you try different format instead of wav?

I use the sunxi-sndi2s as sound card, alsamixer can't show settings.

If select this card, alsamixer wrote: "This sound device does not have any controls."

I think the problem in sunxi-sndi2s driver.
