tinycap command cannot be recorded

yzg — Mon, 12 Dec 2022 01:31:16 GMT

Now I have a problem. After tinymix is used to set the recording quality to high mode, the recording will be interrupted this time. The next time tinycap command is used to record the recording, 100% cannot be recorded, there will be no error message, but the recorded audio is empty.If the recording quality setting layer is in low mode, this problem does not exist

Hi @yzg

Is the sound play okay with the current device?

By the way, let me know which BSP and device you are working with.

And can you share the logcat?

Best regards

Harvey

1，codec is kernel_imx/sound/soc/fsl/fsl_micfil.c

2，board is not evk, it is another board

3，full command:

tinycap test.wav -D 1-d 0-c 2-r 48000-b 16 (Recording works properly)

tinymix -D 1 8 1

tinycap test.wav -D 1 -d 0 -c 2 -r 48000 -b 16 (Failed to record)
