From 723b2b0d36fa7cea81a962af2d40d88520d5a5f1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 30 Aug 2006 16:49:54 +0200 Subject: [ALSA] Clean up and add TLV support to AK4xxx i2c driver - Clean up the code in AK4xxx-ADDA i2c code. - Fix capture gain controls for AK5365 - Changed the static table for DAC/ADC mixer labels to use structs - Implemented TLV entries for each AK codec The volumes in AK4524, AK4528 and AK5365 are corrected with a table to be suitable for dB conversion.
