alexparser Posted November 15, 2016 Share Posted November 15, 2016 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?

thickglass Posted December 14, 2016 Share Posted December 14, 2016 Check your sound mixer settings, make sure if all channels aren't shut, Did you try different format instead of wav? Link to comment Share on other sites More sharing options...
alexparser Posted December 14, 2016 Author Share Posted December 14, 2016 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. Link to comment Share on other sites More sharing options...
