- SNDSTAT_LABEL_* are renamed to SNDST_DSPS_*, and SNDSTAT_LABEL_DSPS becomes SNDST_DSPS. - Centralize channel number/rate/formats into a single nvlist The above nvlist is named "info_play" and "info_rec" - Expose only encoding format in pfmts/rfmts. Userland has no direct access to AFMT_ENCODING/CHANNEL/EXTCHANNEL macros, thus it serves no meaning to expose too much information through this pair of labels. However pminrate/rminrate, pmaxrate/rmaxrate, pfmts/rfmts are deprecated and will be removed in future. This commit keeps ioctls ABI compatibility with __FreeBSD_version 1400006 for now. In future the compat ABI with 1400006 will be removed once audio/virtual_oss is rebuilt.
