I have another issue, Mike. I get no sound output and when I check alsamixer I get cannot load mixer controls: Remote I/O error and then I have issues connecting to the MPD server
Please can you inform me which dac do you use with Archphile?
When do you get no sound?You mean in general?

Strange.. I re-imaged another micro-sd and reconfigured from scratch and now it works. Perhaps it got corrupted. I notice once the MPD start acting up, I start hitting all these issues like the inotify and the alsamixer I/O issue
All your issues are really strange to be honest.
I haven't got a corrupted card for years now. If I were in your shoes I would check the power supplies again.

Indeed, can't make any logical sense out of it. I got the official rpi power supply though, so I think that should be fine. I'm wonder whether its due to improper shutdown that messed up the state of things. Should the mpd be stopped before shutting down?
OMG! What gives? Indeed it's the power supply! Can you believe I swapped the official pi supply with iFi iPower and then it works again? I wonder if it's because I'm using another iPower for the DAC. Now it seems stable and not having intermittent playback issues on reboot. Fingers crossed
May be it's my English but I didn't understand...
Your issues were solved with the iPower or with the official power supply?
Here’s the thing. I use separate power supplies, one for the dac and another for the pi. If I just use 1 power supply for both, I have no issues. But if I use the ipower for the dac, then I must either use another ipower or a powerbank for the pi, otherwise I’ll run into stability issues.
I’ve come to the conclusion that ipower for the dac does not play well with other SMPS, including the original pi power supply.

There is an rt branch maintained in RPI github:
GitHub - raspberrypi/linux at rpi-4.14.y-rt
Users familiar with Linux will be able to experiment. In addition, below you will find the ArchlinuxARM PKGBUILD to modify and be able to create an RT Linux kernel package:
PKGBUILDs/core/linux-raspberrypi at master * archlinuxarm/PKGBUILDs * GitHub
However all of the above are not supported by Archphile. Feel free to experiment but please do not ask any questions if problems occur!

RT kernel will sound different. Would like to experiment and see if I like it better
