Ok, I know this is a complete shot in the dark, but thought it would be worth asking. I’m playing around with a RPi4 running RoonBridge (right now just plugged into a small speaker from the headphone jack but will eventually feed a DAC and headphone amp via USB), no HAT, and nothing else beyond RoonBridge. All is working well and as expected with Roon.
I’d like to run a software VU meter as well on the RPi4 and have had good success with PeppyMeter/peppyalsa which is working well when manually piping audio through the ‘peppyalsa’ software device, but I’m not having any luck getting Roon to pipe audio through peppyalsa so PeppyMeter can pick it up. I’m pretty sure this is by design as Roon writes directly to the hardware so no opp to pipe it through a software device, but in my case Peppy is also writing to “hw:0,0”, so I’m wondering if there’s any opp here to redirect Roon through peppyalsa.
I know, this is a bit ridiculous b/c I’m only messing around with this to get software VU meters to display on Roon data, no real value, but it’s a fun project, I’m a sucker for VU meters, and don’t have the skillset to pursue HW VU meters.
Anyone ever done anything like this?
