Subject: ASoC: SOF: ipc4-topology: Convert FLOAT to S32 during blob selection
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=816f291fc23f325d31509d0e97873249ad75ae9a;p=thirdparty%2Fkernel%2Flinux.git

ASoC: SOF: ipc4-topology: Convert FLOAT to S32 during blob selection

SSP/DMIC blobs have no support for FLOAT type, they are using S32 on data
bus.

Convert the format from FLOAT_LE to S32_LE to make sure that the correct
format is used within the path.

FLOAT conversion will be done on the host side (or within the path).
