I have a Wandboard platform (which has an SGTL5000 audio codec) running a Linux image (Linux wandboard 3.14.28_1.0.0_ga-wandboard). While I use this platform with headphones
<WANDBOARD/LINEOUT> ------> <HEADPHONES>
it works OK.
On the other side, when I used a little amplifier LM386
<WANDBOARD/LINEOUT>-------> <resistor><LM386><SPEAKER>
------------------------- -------------------------------------------
POWER SOURCE 1 POWER SOURCE 2 (Both grounds are connected)
, it works fine. However, after some minutes, it stop working. In order to recover it, I rebooted the system, but without any success. In addition, once the reboot was finished, the "dmesg" command returned the following lines
[ 5.491631] imx-sgtl5000 sound.20: ASoC: CODEC (null) not registered
[ 5.496951] imx-sgtl5000 sound.20: snd_soc_register_card failed (-517)
[ 5.502196] platform sound.20: Driver imx-sgtl5000 requests probe deferra
The only way I found to restart the system is power-cycling the board.
Do you know any way I have to follow in order to recover the IC without need power-cycling the board? In addition, which circuit recommendation do you suggest?
Thank you very much for your help and support.
