From 72216211c7a5f29510a2f50dbdc70b35af44fb3a Mon Sep 17 00:00:00 2001 From: dvdli Date: Wed, 28 Oct 2020 22:22:27 +0800 Subject: AOSP CL "Add pcm_get_poll_fd" https://android.googlesource.com/platform/external/tinyalsa/+/b42510d55bafc96805a44bd6ac40faac28ebd219 commit b42510d55bafc96805a44bd6ac40faac28ebd219 author Dylan Reid Add pcm_get_poll_fd Similar to ALSA snd_pcm_get_poll_fd, this will allow a user to wait for a sound device to have data in a poll(2) call. The hotword thread will use this to wait for a message on its socket or for audio data to become ready.
