From 854b66e44260320c21ebe4b8a18e189f2e45b5be Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 8 Sep 2006 12:27:38 +0200 Subject: [ALSA] ak4xxx - Remove bogus IPGA controls Remove IPGA volume controls and merge the IPGA range to ADC volume controls. These two volumes are not really independent but connected simply in different ranges 0-0x7f and 0x80-max. It doesn't make sense to provide two controls. Since both 0x7f and 0x80 specify 0dB, a hack is needed for IPGA range to skip 0x80 (increment one) for such controls.
