Existing code does not allow to change this profile while doing gapless playback. This patchset adds new SNDRV_COMPRESS_SET_CODEC_PARAMS IOCTL along with flags in capablity structure to allow userspace to set this new parameters required which switching codec profile, either for gapless or cross fade usecase. thanks, srini Changes since v1: - split patch into smaller chuncks, - bump up the version - added flags in compress capablity structure - added user for this new functionality. - add this new call in Documentation.
