Since there is some interest in the AudioPraise HDMI Audio Extractor (I even bought one after discovering it on this site), I thought I'd just add a few comments on my own experience. As I said elsewhere, all my audio/video feeds into my AVR via HDMI (cable, DVD, PlayStation, Roon Nuclues+), and rather than use my AVR's DAC, I run the output through HDMI into the AudioPraise HDMI Audio Extractor (which has digital audio out plus HDMI video out to my tv), then to my DAC, then to my amps, and then to my speakers.
Two minor issues I encountered are:
1) I had no way of controlling volume, so I also had to buy a volume controller (I bought a MiniDSP SHD Studio for digital volume control)
2) Twice in about a month, it stopped processing HDMI, and I had to power it down and back up again to get it to work (it took a while at first to troubleshoot this issue, but now that I know the fix it's easy to resolve)
Overall, I'm very satisfied with the audio quality I'm getting with my new setup. I just thought I'd share the above in case anyone was interested.
