I dunno. I don't think it's an issue but I'm not a PHP expert and so if you can suggest some configuration changes I'll try them out.
For DSD format the only configuration where MPD Hardware volume will work is if the audio device has the capabilities listed below.
1. Hardware volume controller
2. Either DoP or Native DSD bitstream support
3. DAC chip performs volume attenuation during some part of digitally filtering DSD format
There are number of DACS that do this including Audiophonics 9028/9038 DAC, Allo Katana, Revolution and Boss2 DAC's, Several Topping models, other USB DAC's, etc.
