From 31e8960b35975ed235d283d6fb95d0e28dffded0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 8 Jan 2008 18:09:57 +0100 Subject: [ALSA] Remove PCM sleep_min and tick The 'tick' in PCM is set (again) via sw_params. And, nobody uses this feature at all except for a command line option of aplay. (This is literally 'nobody', as I checked alsa-lib API calls in all programs in major distros.) Above all, if we need finer wake-ups for the position update, it's basically an issue that the driver should solve, not tuned by each application.
