The branch main has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=716924cb4832ea0a440daf09913a06f3166f243e commit 716924cb4832ea0a440daf09913a06f3166f243e Author: Ed Maste <emaste@FreeBSD.org> AuthorDate: 2022-06-21 18:50:04 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2022-06-21 18:50:04 +0000 Retire snd_sbc ISA sound card driver Along with the snd_sb8 and snd_sb16 drivers. They supported ISA Creative Sound Blaster and compatible sound cards. Note that isa/sb.h is not removed, as it is still used by some PCI sound card drivers. ISA sound card drivers are deprecated as discussed on the current[1] and stable[2] mailing lists. Deprecation notices were added in e39ec8933be4 and MFCd to stable branches. Driver removals are being committed individually so that specific drivers can be restored if necessary (either in FreeBSD or by downstream projects).
