commit ede0236d3b34a89bae7795f0f45696d4d94ce138 Author: Christos Margiolis <[email protected]> AuthorDate: 2026-06-24 13:47:05 +0000 Commit: Christos Margiolis <[email protected]> CommitDate: 2026-06-24 13:47:05 +0000 sound: Retire unused SD_F_EQ_PC This flag is neither set anywhere, nor is there a way to set it from userland, so it is effectively useless, and currently the effect is that EQ can only be enabled for primary playback channels. Retire the flag and keep this behavior, and think later whether we want to allow virtual channels to get their own EQ feeder as well.
