commit ac0068384a2228670327fe56bef9e8168c6996d0 Author: Christos Margiolis <[email protected]> AuthorDate: 2026-06-09 13:36:48 +0000 Commit: Christos Margiolis <[email protected]> CommitDate: 2026-06-18 19:33:35 +0000 virtual_oss(8): Make sndstat FD global There is no reason to have per-profile copies, plus this way we open /dev/sndstat multiple times if more than 1 profile is created. Also close the FD on exit to avoid leaking.
