The branch main has been updated by christos: URL: https://cgit.FreeBSD.org/src/commit/?id=968e748c439a50ad0a1a4463f4753f58a2bdaf9f commit 968e748c439a50ad0a1a4463f4753f58a2bdaf9f Author: Goran Mekić <meka@tilda.center> AuthorDate: 2026-06-27 13:41:57 +0000 Commit: Christos Margiolis <christos@FreeBSD.org> CommitDate: 2026-06-27 13:41:57 +0000 snd_dummy: advance pointers for both channels Previously only the play pointer advanced each tick; the record channel refilled the whole buffer with silence and left the DMA pointer at 0. Advance the record pointer by one block per tick and fill that block with silence, so the DMA pointer changes and mmap kqueue consumers can track progress.
