From 2ab6aaca4dfe1265006dae3f3cd0fd838f9bf2af Mon Sep 17 00:00:00 2001 From: Dmitry Sutyagin Date: Sat, 5 Nov 2016 13:54:12 -0700 Subject: [PATCH] kernel: add SND_PCM_TIMER to kmod-sound-core FS#256 Fix audio not working due to unset SND_PCM_TIMER. CONFIG_SND_PCM_TIMER is required for ALSA to work (at least for some audio devices), otherwise applications using sound may fail. Can be reproduced by installing "alsa-utils-tests" and running "speaker-test": ... ALSA lib pcm_direct.c:1159:(snd1_pcm_direct_initialize_poll_fd) unable to open timer 'hw:CLASS=3,SCLASS=0,CARD=0,DEV=0,SUBDEV=0' ALSA lib pcm_dmix.c:1106:(snd_pcm_dmix_open) unable to initialize poll_fd Playback open error: -19,No such device The kernel size does not increase, only the size of the kernel module increases.
