How many numbers do you really need ?
Because simple-card needs many parameters,
thus I will get below warning.
# It is not yet happen on upstream kernel, but will be
warning: the frame size of 2280 bytes is larger than 2048 bytes [-Wframe-larger-than=]
This warning doesn't appear if SNDRV_MAX_LINKS was 64.
Can we reduce it ?
Thank you for your help !!
Best regards
