Thank you Richard. First post updated.
I guess they also made some changes to the HDMI sound bypass drivers. Since installing, my music that was ripped using Windows Media Audio 9.2 Lossless VBR Quality 100, 44 kHz, 2 channel 16 bit 1-pass VBR, sounds overdriven.
Blame Realtek for that as it is their chip and drivers that provide the HDMI audio. That and unless there is a newer version available to AMD (likely) from Realtek, the last HDMI driver released by Realtek (standalone download directly from them) is 3 years old.
HDMI audio is provided by the graphics card not the sound chip. https://en.wikipedia.org/wiki/HDMI
Older graphics cards did need a separate connection but hasn't been that way for quite some time now. My laptop gets HDMI video and audio from the Intel HD 4000 graphics.
There is a Realtek chip on the card for the audio (nothing to do with onboard audio). Without it there would be no audio on the card.
I'm not so sure it is necessarily a Realtek chip but you could be right. Still it is up the the graphics card manufacturer to ensure it passes the audio correctly through the HDMI. I don't think Realtek has anything to do with the drivers for it. May be wrong.
