Pack 1136 volume adjustment not working and need quick setting option for turning bitstreaming audio on and off

Weird bug with the latest pack 1136, when ur mouse cursor on bottom of the seek bar or control bar u cannot adjust volume via mouse scroll, u have to move your cursor to the screen which u cant tell how many percent are u adjusting the volume bar, and is it possible to enable quick select audio out via bitstream or analog, eg when im using my hdmi receiver i decide to use my headphone i want to listen to dts, and lossless format it wont auto switch to internal decoding, or when i want to bitsrteam it still stuck on software decoding vice version, is there an option to quickly or automatically set it?
