From 67fc2c25d727888cb45a847971771f34674b68ff Mon Sep 17 00:00:00 2001 From: Jonathan Aillet Date: Sun, 3 Jun 2018 19:16:32 +0200 Subject: Handle hal status using card presence and mixer init Test audio card presence at hal startup using alsacore call. Handling a new state of hal. Move alsacore link files into 4a-hal-controllers. Check state of hal before mixer initialization call. Actualize hal state if mixer initlialization ends well. Add a sndCardId filed to 'SpecificHalData' structure which will contain audio card if (from alsa).
