[Qemu-devel] [PATCH] hda-codec: use smaller dynamic range for input amplifier

2015-04-21 Thread Martin Wilck
This patch addresses the following problem: Moving the input volume slider 0% to 1% in a Win7 guest causes the the "gain" values in the emulated HDA codec HW to jump from 0 to 40. This makes it impossible to control sound volume in the low-gain range using the windows guest. This is related to how
