[Sound-open-firmware] [PATCH] Component ABI: Check for valid ABI header for COMP_CMD_SET_DATA command
by Seppo Ingalsuo 25 Sep '17

25 Sep '17

This patch adds the code to check the generic ABI header fields and reject data with invalid header. The individual components those use ABI need to check the component specific fields in addition.

[Sound-open-firmware] [PATCH] Volume: Add 24 to 24 bit samples volume processing
by Seppo Ingalsuo 25 Sep '17

This patch adds to component volume S24_4LE to S24_4LE processing. The macro from audio/format.h is used to compute shifts needed for product.
