Hi, I have been using im6q+wm8962+alsa to do some sound tests.
Here is what I did:
and using using ctrl+c to interrupt playback.
I did this repeatedly and Most of the times xxx.wav can be well played but occasionally,
there was no sound came out from speaker. But aplay was blocked and seemed it was
playing, though there is no sound. There is no output signal from sound card.
I wonder if something happened to sound card.
